Player Reports

  1. 1. Julio Rodriguez | OF
    Julio Rodriguez
    Born: Dec 29, 2000
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 205
    Drafted: Dominican Republic, 2017.
    Signed By: Eddy Toledo/Tim Kissner

    Hitting: 60. Power: 70. Running: 45. Fielding: 55. Arm: 70.

    TRACK RECORD: Rodriguez signed with the Mariners during the 2017 international period for $1.75 million. After starting his pro career in the Dominican Summer League in 2018, Rodriguez jumped to full-season ball for his first U.S. experience and put up strong numbers at both low Class A West Virginia and high Class A Modesto despite missing nearly two months with a broken left hand. Rodriguez was anything but intimidated by more advanced California League pitchers, batting .462/.514/.738 in 17 games with the Nuts and earning hyperbolic praise from league observers. Rodriguez suffered a hairline fracture in his left wrist diving for a ball during summer camp in 2020 and sat out most of the summer recovering. He made up for lost time with a strong instructional league stint in the fall before reporting to Escogido of the Dominican League.

    SCOUTING REPORT: Rodriguez is a precocious physical specimen often referred to as a “manchild.” His elite bat speed and quick hands allow balls off his bat to register big exit velocities—he peaked at 111 mph during instructional league—and his swing takes a solid path through the zone. He has an excellent feel to hit and an advanced ability to make adjustments at the plate. With his natural hitting ability and comically easy plus-plus raw power, he projects to be a plus hitter capable of hitting 30-35 home runs per year with power to all fields. As Rodriguez continues to mature in his already-strong body, he projects to be a fringe-average runner who is faster underway than he is getting out of the box. Rodriguez gets good reads and jumps in the outfield and projects to be at least an average defender with solid instincts. He’ll settle into right field as a polished defender with an accurate, plus-plus arm. Rodriguez still has some room for development, with scouts seeing him give away at-bats at times, and he’ll need to continue to work on his conditioning to keep his solid, muscular body in shape. He is a bright, effervescent individual with outstanding makeup. He rapidly learned English after signing with the Mariners and shows the confidence and personality to be a leader both on and off the field.

    THE FUTURE: Rodriguez will be just 20 years old in 2021 and is likely to begin the year in Double-A. While the Mariners have no reason to rush Rodriguez to Seattle, it wouldn’t be surprising to see him there before the end of the year. His talent and personality give him a chance to be a perennial all-star and the Mariners’ face of the franchise through the 2020s.

  2. 2. Jarred Kelenic | OF
    Jarred Kelenic
    Born: Jul 16, 1999
    Bats: L Throws: L
    Ht.: 6'1" Wt.: 196
    Drafted: HS—Waukesha, Wis., 2018 (1st).
    Signed By: Chris Hervey (Mets).

    Hitting: 70. Power: 60. Running: 55. Fielding: 50. Arm: 60.

    TRACK RECORD: Kelenic was one of the top high school players in the 2018 draft and was selected sixth overall by the Mets. His tenure lasted only one summer before he was traded to the Mariners in the deal that sent Robinson Cano and Edwin Diaz to New York. Kelenic jumped three levels up to Double-A in his first year with the Mariners. He spent the 2020 season at the alternate training site.

    SCOUTING REPORT: Kelenic is an elite young hitter who projects to be an offensive force. He attacks pitches he can hit with authority and lays off pitches that might result in weak contact or swings and misses. Most impressive is his ability to learn and adapt to pitchers’ plans of attack from at-bat to at-bat. Kelenic uses a swing so short and powerful it allows him to wait a beat longer before pulling the trigger. He has good strike-zone awareness, though at times he can get locked up on balls inside. Kelenic is a plus runner who may slow down as he matures but should still steal plenty of bases with his advanced instincts and athleticism. Kelenic’s main focus at the alternate site was his defense. He is an average defender in center field but needs to improve his focus and decisiveness.

    THE FUTURE: Kelenic has an all-star potential and his major league debut is on the horizon in 2021.

  3. 3. Logan Gilbert | RHP
    Logan Gilbert
    Born: May 5, 1997
    Bats: R Throws: R
    Ht.: 6'6" Wt.: 225
    Drafted: Stetson, 2018 (1st round).
    Signed By: Rob Mummau.

    Fastball: 60. Slider: 55. Changeup: 60.Curveball: 60. Control: 55.

    TRACK RECORD: The Mariners drafted Gilbert 14th overall in 2018 after an impressive college career at Stetson that included winning Atlantic Sun Conference pitcher of the year honors as a sophomore. Gilbert battled mononucleosis and had toe surgery after signing, but he showed no ill effects in his pro debut. He was named the Mariners’ minor league pitcher of the year in 2019 after jumping three levels to Double-A. He spent 2020 at the alternate training site and showed an uptick in stuff.

    SCOUTING REPORT: Gilbert is a tall, long-limbed righthander who dominates with his fastball. His heater generally sits 93-95 mph and plays up with riding life. He generates tremendous extension from his 6-foot-6 frame. Gilbert’s 11-to-5, downer curveball flashes plus, and his changeup made huge strides at the alternate site to give him a third potential plus offering. He also has a horizontal slider he boosted into the low 80s with increased sharpness that flashes above-average. Everything Gilbert throws plays up with his advanced pitchability and above-average control despite a long arm action.

    THE FUTURE: Gilbert still has to show he can maintain his improved stuff over a full season. If he can, he has front-of-therotation upside.

  4. 4. Emerson Hancock | RHP
    Emerson Hancock
    Born: May 31, 1999
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 213
    Drafted: Georgia, 2020 (1st round).
    Signed By: John Wiedenbauer.

    Fastball: 60. Slider: 55. Changeup: 60. Curveball: 50. Control: 60.


    TRACK RECORD: Hancock zoomed up draft boards after an outstanding sophomore season at Georgia in 2019 that included a 1.99 ERA. His four college starts in 2020 before the season shut down weren’t as gaudy, but his assortment of plus pitches and outstanding control were enough for the Mariners to draft him sixth overall and sign him for $5.7 million. Hancock participated at the Mariners’ alternate training site and instructional league, but he did not pitch because of the long layoff after the college season.

    SCOUTING REPORT: Hancock stands out for his command, frame, delivery and pitch mix. He starts with a plus fastball that sits 93-97 mph with heavy sinking action. The Mariners will try to optimize the life on Hancock’s fastball to get it to play better up in the zone. Hancock’s low-80s slider is above-average with the potential to be plus. His tumbling changeup consistently misses bats against both righthanded and lefthanded batters. Hancock rounds out his arsenal with a seldom-used curveball. He’s a natural athlete with a clean delivery that allows him plus control.

    THE FUTURE: Hancock profiles as at least a No. 3 starter and perhaps better if he refines his breaking pitches. High Class A is his likely assignment coming out of spring training.

  5. 5. Noelvi Marte | SS
    Noelvi Marte
    Born: Oct 16, 2001
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 187
    Drafted: Dominican Republic, 2018.
    Signed By: Eddy Toledo/Tim Kissner.

    Hitting: 60. Power: 55. Running: 50. Fielding: 50. Arm: 60.

    TRACK RECORD: Marte signed with the Mariners for $1.55 million in 2018 and ranked as the Dominican Summer League’s top prospect the following year after making his pro debut. He led the DSL with 134 total bases. Marte was poised to jump to the U.S. in 2020, but instead he spent the summer as one of the youngest players at the Mariners’ alternate training site. He finished the year at instructional league in Arizona.

    SCOUTING REPORT: Marte is extremely young but has a chance to be a special player at a premium position. His hands, bat speed and feel for the barrel allow him to make contact against all different pitch types and hit with power to all fields. He projects to be a plus hitter with above-average power in the middle of the order. Marte has added muscle to his frame and is just an average runner, and he may slow down more if he keeps growing. Scouts are split on whether Marte can stay at shortstop. His range is a little short, but he has the actions and IQ to handle the position as long as he doesn’t grow too much more. His plus arm is accurate and he can make throws on the move.

    THE FUTURE: If Marte does eventually move to third base, he has more than enough bat to profile as a potential all-star. He should open the 2021 season in full-season ball.

  6. 6. Taylor Trammell | OF
    Taylor Trammell
    Born: Sep 13, 1997
    Bats: L Throws: L
    Ht.: 6'2" Wt.: 215
    Drafted: HS—Kennesaw, Ga., 2016 (1st round supplemental).
    Signed By: Jon Poloni (Reds).

    Hitting: 55. Power: 45. Running: 55. Fielding: 50. Arm: 40.

    TRACK RECORD: Trammell has been on the move frequently the last two seasons. The 2018 Futures Game MVP with the Reds, he was traded to the Padres at the 2019 trade deadline and sent to the Mariners at the 2020 deadline as part of the package for Austin Nola. He joined the Mariners at the alternate training site in Tacoma and finished the year in instructional league.

    SCOUTING REPORT: Trammell has the ingredients to be an offensive asset, but he hasn’t put them all together. He has size, strength and bat speed and showed improved plate discipline at instructional league. His swing is a bit long, and there are timing issues that lead to holes pitchers can exploit. Trammell stands out for elite athleticism stemming from his background as an all-state running back in high school. He’s since filled out his lower half and is more of an above-average than plus runner. Trammell’s improved instincts and routes in the outfield stood out this summer and give him a chance to stay in center field. His arm is below-average but accurate.

    THE FUTURE: Trammell needs a full season at Triple-A, but his solid makeup and work ethic are positive signs that he will make the necessary adjustments.

  7. 7. George Kirby | RHP
    George Kirby
    Born: Feb 4, 1998
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 201
    Drafted: Elon, 2019 (1st round).
    Signed By: Ty Holub.

    Fastball: 60. Slider: 60. Changeup: 55. Curveball: 50. Control: 70.


    TRACK RECORD: Kirby was known for impeccable control at Elon and was drafted 20th overall by the Mariners in 2019. That trait showed up in his professional debut at short-season Everett, when he went 23 innings without walking a batter. He spent 2020 at the Mariners’ alternate training site remaking his body to add velocity and power to his arsenal.

    SCOUTING REPORT: Kirby’s fastball sat in the low 90s in college and touched 95 mph, but he showed an uptick in his pro debut and took another jump in 2020. Kirby’s fastball averaged 96 mph and peaked at 99 at the alternate site, and that extra velocity did not come at the expense of his plus-plus control. He also added movement to his fastball, making it a bona fide plus pitch. Kirby’s mid-80s slider with deep, crisp break is another plus pitch, while his low-80s, downer curveball projects as average. Kirby doesn’t throw his 85-87 mph changeup often, but it has good action and has the potential to be an above-average pitch.

    THE FUTURE: Kirby has to show he can maintain his velocity uptick over the course of a full season in a competitive environment. If he can, he’ll be a potential mid-rotation starter or better.

  8. 8. Cal Raleigh | C
    Cal Raleigh
    Born: Nov 26, 1996
    Bats: B Throws: R
    Ht.: 6'3" Wt.: 215
    Drafted: Florida State, 2018 (3rd round).
    Signed By: Rob Mummau.

    Hitting: 40. Power: 60. Running: 30. Fielding: 45. Arm: 55.

    TRACK RECORD: Raleigh’s big power at Florida State led the Mariners to draft him in the third round in 2019, and he quickly showed it transferred to pro ball. Raleigh hit 29 home runs in his first full season as he jumped to Double-A. He spent 2020 at the alternate training site and stood out in instructional league, where his eight home runs led all Mariners prospects.

    SCOUTING REPORT: The burly, switch-hitting Raleigh has plus raw power he gets to in games. He has slightly below-average bat speed, but he worked to shorten his swing at instructs and still barrels balls hard in the air. His home run power is almost exclusively from the left side, but he has enough strength to drive balls from the right side, too. Some scouts are concerned he’ll struggle with better velocity, but his power should compensate for low batting averages. Whether Raleigh stays at catcher will depend on how he maintains his body and mobility. He has a thick lower half and keeps getting bigger. Because of his size, he catches on one knee but has a quick transfer and makes accurate throws. He is a solid receiver and communicates well with pitchers.

    THE FUTURE: Raleigh could be the rare catcher who hits enough to DH on occasion. He’ll see Triple-A in 2021.

  9. 9. Juan Then | RHP
    Juan Then
    Born: Feb 7, 2000
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 178
    Drafted: Dominican Republic, 2016.
    Signed By: Eddy Toledo.

    Fastball: 60. Slider: 60. Changeup: 55. Control: 55.


    TRACK RECORD: Then first signed with the Mariners in 2016 and was traded to the Yankees one year later. The Mariners reacquired the lanky righthander in 2019 in a trade for Edwin Encarnacion, and Then reached low Class A by the end of that season. Then spent 2020 at the Mariners’ alternate training site before reporting to Arizona for instructional league.

    SCOUTING REPORT: Then added 10 pounds of good weight prior to spring training and dropped his arm slot to a more natural position. Those changes resulted in a big uptick in his velocity. Then’s plus fastball sat 96-97 mph in the fall and began touching triple- digits, up from his previous 92-96. It’s a four-seamer with tail and sink, but he can also manipulate it to generate average movement to his glove side. His hard, sharp slider also added power to flash plus at 87-91 mph, and he has a good feel for an above-average changeup at 88-91 mph with deception and a good bottom. Then uses a low three-quarters slot with a smooth arm action and a clean, repeatable delivery that yields above-average control.

    THE FUTURE: Then has the attributes to be a mid-rotation starter, but he could also thrive in a late-inning bullpen role. He will likely start 2021 in high Class A.

  10. 10. Andres Munoz | RHP
    Andres Munoz
    Born: Jan 16, 1999
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 243
    Drafted: Mexico, 2015.
    Signed By: Trevor Schumm (Padres)

    Fastball: 80. Slider: 55. Control: 40.

    TRACK RECORD: The Padres purchased Muñoz’s rights from the Mexican League for $700,000 in 2015. He quickly grew into one of the hardest throwers in baseball. He made his big league debut as a 20-year-old and struck out 30 of the 97 batters he faced in relief, but his 2020 season was wiped out by Tommy John surgery. The Mariners acquired him with Taylor Trammell, Ty France and Luis Torrens in the deadline trade that sent Austin Nola to San Diego.

    SCOUTING REPORT: Muñoz’s top-of-the-scale fastball and an above-average slider allow him to project as a late-innings weapon if he refines his control. Prior to the injury, his four-seamer sat 99-100 mph and touched 103 with explosive life that allowed the pitch to play up even further. He can elevate it to miss bats or spot it on either corner. His mid-80s slider needs consistency, but at its best the pitch generates swings and misses with short, late glove-side cut. Muñoz’s control is below-average, but most concerning is his injury history. He battled elbow issues for years before surgery and has thrown more than 26 innings only once in five seasons.

    THE FUTURE: Muñoz is set to complete his rehab in mid 2021 and could join Seattle’s bullpen late in the season. He has the potential to become the Mariners’ closer.
