BA Grade: 60. Risk: High. Tool Grades: Hit: 50. Power: 60. Speed: 40. Field: 50. Arm: 60. Track Record: Mauricio ranked as the No. 3 prospect in the 2017 international signing class—Rays shortstop Wander Franco was No. 1—and signed for $2.1 million. That set a franchise bonus record for a Latin American amateur that was surpassed by Venezuelan catcher Francisco Alvarez a year later. Mauricio shined in his pro debut in the Rookie-level Gulf Coast League in 2018, ranking as the league’s No. 2 prospect. The Mets pushed him to the low Class A South Atlantic League in 2019, where he, Phillies shortstop Luis Garcia and Mariners outfielder Julio Rodriguez were the only 18-year-old regulars on Opening Day. Mauricio produced modestly but impressed scouts enough to rank as the league’s No. 5 prospect. Scouting Report: Mauricio has the potential to impact games with his bat and as a left-side-of-the-infield defender, though his rosiest outlook is predicated on projection. Mauricio is lanky and long-limbed, and it’s an open question as to whether his narrow, 6-foot-3 frame will add significant mass. The good news is that he is an elite athlete who can stay on the dirt and already stands out for making loud contact with an easy swing from both sides of the plate. The bad news is that his long levers create unavoidable length to his swing that could impact his batting average down the line. Mauricio uses an all-fields hitting approach and adjusts well to breaking and offspeed stuff, but he tends to be overaggressive and put too many pitchers’ pitches in play. That contributed to him having one of the highest groundball rates in the SAL. He has no problem dropping the bat head on inside pitches for deep power to his pull side when he’s locked in on a pitcher. Scouts came away pleasantly surprised by Mauricio’s defensive play. He has the plus arm, body control and quick first step to make all the plays—and in all the directions—required at shortstop. He won’t be a factor on the basepaths because he’s a fringe runner who figures to slow down as he matures physically. The Future: Scouts who like Mauricio see at least an average hitter with plus power who has the grace and hands of a major league shortstop or possibly a third baseman. The hot corner is probably the position for which he’s destined with the Mets, who have pure shortstops Amed Rosario and Andres Gimenez ahead of him on the depth chart. Mauricio should spend the bulk of 2020 at high Class A St. Lucie and begin to enter the big league picture in 2022.
BA Grade: 60. Risk: Very High Tool Grades: Hit: 60. Power: 50. Run: 40. Field: 60. Arm: 60. Track Record: The Mets loved Alvarez’s combination of tools when they signed him, but they were equally enamored of his work ethic and grinding mentality. Rival scouts mirrored the Mets’ praise after getting a look at the 17-year-old catcher at a pair of Rookie-level stops in his 2019 pro debut. Alvarez hit .462 during a week in the Gulf Coast League before his manager implored the Mets to promote him. He continued to hit as the youngest player in the Appalachian League, ranking as the circuit’s No. 1 prospect. Scouting Report: Alvarez has the potential to be a franchise catcher. He handles velocity and stays on breaking balls, while showing elite bat-to-ball ability and power straightaway and to the opposite field. Alvarez has special potential with the bat and could be a plus overall hitter with power. He has all the ingredients behind the plate to start for a winning team, including a high energy level and the massive hands and forearms of a big league backstop. He receives well and keeps the running game in check with a plus arm. On his to-do list are fine-tuning his pitch framing and game-calling. The Future: Alvarez desires to be great and has put in the work to learn English and condition his body. Look for him to make a splash in full-season ball in 2020 and get on the big league radar in 2023.
BA Grade: 55. Risk: High Tool Grades: Hit: 55. Power: 60. Run: 40. Field: 50. Arm: 60. Track Record: Baty played basketball and football at Lake Travis High but shone brightest in baseball, where he was Gatorade player of the year as a junior and then even more prolific as a senior. He hit .624 with 19 homers in 93 at-bats in his draft year and was recognized by scouts as one of the top hitters, top power hitters and most disciplined hitters in the 2019 high school draft class. The complicating factor for Baty was his age—19 and a half on draft day—which dropped him to the Mets at No. 12. He signed for $3.9 million and showed power and patience in a 51-game pro debut focused at Rookie-level Kingsport. Scouting Report: Baty’s value is concentrated in his lefthanded bat, and he is a better athlete than his physical 6-foot-3 frame suggests. He might have fielded Division I offers as a quarterback had he not dropped football as a sophomore and he can dunk a basketball. His prodigious power plays to both his pull side and the opposite field and is supported by high-end exit velocities and a swing geared for loft. Baty can handle velocity, doesn’t often chase out of the zone and takes his walks, so the Mets expect him to be a solid-average hitter or better. He is a notoriously hard worker who handled third base better than expected in his pro debut, showing average potential and a plus arm that once fired 92 mph heat off the mound in high school. The Future: Baty turned 20 in November and because of his age doesn’t have the typical grace period of a prep pick. He needs to hit the ground running at low Class A Columbia and move up at least one level during the season.
BA Grade: 60. Risk: Extreme Tool Grades: FB: 60. CB: 70. CHG: 55. CTL: 55. Track Record: Allan ranked as the top high school pitching prospect in a 2019 draft class regarded by scouts as thin on prep arms. A mid-first round talent, Allan fell to the third round because he priced himself at $4 million in a draft in which only Quinn Priester, taken 18th overall by the Pirates, cleared $3 million. Allan signed for $2.5 million, the second-highest bonus for a high school pitcher in the draft and the most the Mets could offer after signing first-rounder Brett Baty and second-rounder Josh Wolf for a combined $6.05 million of their $8.225 million bonus pool. Allan signed in late June and made six brief appearances, mostly in the Rookie-level Gulf Coast League. Scouting Report: The Mets viewed Allan as the best pitcher in the 2019 draft because of his combination of stuff, physicality, competitive makeup and a sound, repeatable, low-effort delivery. He already looks like a major league starter, and while that may preclude projection to the same degree as other teen pitchers, his present stuff is plenty good. He topped out at 97 mph in his pro debut and pitched at 93-96 with a plus fastball. His attention-getting 77-82 mph curveball has double-plus potential and a consistent spin rate in excess of 2,500 revolutions per minute. He locates his curve well but needs to fine-tune command of the pitch. Allan will receive a crash course in changeup usage in pro ball, but the pitch projects as solid-average. The Future: Allan’s stuff is firm and plays in the strike zone, giving him an absolute ceiling of No. 2 starter and the chance to move quickly for a high school pitcher. He should have no trouble opening 2020 at low Class A Columbia.
BA Grade: 50. Risk: Medium Tool Grades: Hit: 50. Power: 40. Run: 60. Field: 60. Arm: 60. Track Record: The No. 2 prospect in the 2015 international signing class, Gimenez shot to Double-A as a 19-year-old in 2018 but stalled offensively in a return to the Eastern League in 2019. He hit just .235 in the first half before showing signs of life in the second half, hitting .261/.306/.406 in 70 games with six of his nine home runs. He hit .358 with a .970 OPS in the Arizona Fall League, where he focused on keeping his upper and lower halves synced, trusting his hands and using all fields. Scouting Report: Gimenez is a heady player who will flash all five tools but impacts games mostly with his glove, arm and plus speed. He is one of the best defensive shortstops in the minors and commands the infield at a tender age. He minimizes mistakes with reliable hands and a plus, accurate arm. Gimenez tinkered with his swing early in 2019 in an effort to generate more power, but it didn’t take. At his best he is a disciplined, line drive-oriented hitter who should grow into double-digit power to go with an average overall bat. He has improved his speed to plus and tuned up his basestealing aggressiveness. The Future: Gimenez is athletic, but a lack of physicality limits his offensive upside. His defensive acumen will afford him opportunities to develop his bat in the big leagues, where outlooks range from starting middle infielder to a utility role.
BA Grade: 50. Risk: High Tool Grades: Hit: 45. Power: 60. Run: 30. Field: 40. Arm: 60. Track Record: Following an encouraging 2018 season in Rookie ball that included 11 homers and nearly as many walks as strikeouts, Vientos didn’t have much to show through his first month at low Class A Columbia in 2019. A struggle to pick up spin on breaking pitches from righthanders led him to a .233 average and .100 isolated slugging through 35 games. Vientos picked up the pace afterward and produced a .205 ISO over his next 65 games before tailing off in mid-August. Scouting Report: Power is going to be Vientos’ ticket to advancement, and making the best possible swing decisions will be the key to reaching that goal. He sees lefthanders well and can impact his pitch with plus bat speed, strong hand-eye coordination and loft power. He lacks the natural feel for barrel manipulation and fluidity to be anything more than an adequate hitter for average. Drafted as a shortstop, Vientos shifted to third base in 2018. He throws well and his hands work, but below-average speed, mobility and footwork limit his defensive upside. The Future: Vientos is physically mature for his age and faces a possible move to first base down the line, but the thunder in his bat is real and could make him an attractive corner masher.
BA Grade: 50. Risk: High Tool Grades: FB: 60. CB: 60. CHG: 45. CTL: 45. Track Record: Szapucki burst on the scene in 2016 when he struck out nearly 15 per nine innings at a pair of short-season stops. He failed to build on that success in 2017, when he had Tommy John surgery in July that knocked him out for all of 2018. Szapucki returned in 2019 and cruised through two Class A stops on tight pitch counts before making one Double-A start to close the season. Scouting Report: Szapucki has experienced the highs and lows of professional baseball. Likewise, his pitches explore the highs and lows of the strike zone, and his high-spin rate arsenal makes him a prototype pitcher for baseball today. Szapucki’s sneaky fastball sits 91-93 mph with carry up in the zone and he can reach 95 when needed. His curveball is the best in the system and features deep breaking action in the low 80s to change hitters’ eye levels. He has good feel for a near-average changeup and began throwing it with more conviction as his comfort level grew in his return. The Future: Szapucki has a major league arm, though it remains to be seen if it fits in the rotation or bullpen. The Mets must add him to the 40-man roster in November to exempt him from the Rule 5 draft. Szapucki's focus in 2020 will remain building arm strength and gaining reps, most likely at Double-A.
BA Grade: 55. Risk: Extreme Tool Grades: FB: 60. CB: 60. CHG: 50. CTL: 55. Track Record: Wolf improved his velocity as a high school senior to sit in the mid-90s and bump 97 mph after he had ranged from 88-92 on the 2018 showcase circuit. Scouts took immediate notice of his velocity spike as well as his continued ability to throw strikes, making Wolf one of the more prominent pop-up prospects for the 2019 draft. The Mets selected him in the second round and went nearly $800,000 over slot to sign him. Wolf made five appearances in the Rookie-level Gulf Coast League, where he struck out 12 and walked only one in eight innings. Scouting Report: Wolf throws two plus pitches, shows an aggressive mound demeanor that endears him to scouts and is a twitchy athlete with a quick arm and projectable frame. He pitched at 94 mph with life in his pro debut and ranged from 91-96 while continuing to throw strikes. Wolf shows aptitude for spinning a 79-83 mph curveball that projects as a plus pitch once he develops the command to shape it consistently. Like most high school righthanders, he doesn’t have a lot of experience throwing a changeup but has the ingredients to develop an average one. The Future: Wolf needs to add about 15 pounds to his frame, but his athleticism and presence give him a mid-rotation ceiling. He should be ready for low Class A in 2020.
BA Grade: 50. Risk: High Tool Grades: FB: 50. SL: 60. CHG: 45. CTL: 50. Track Record: The Mets had a good feeling about Smith in 2018, when they drafted him in the seventh round and watched him dominate New York-Penn League competition with an 0.76 ERA in 23.2 innings. He looked even better in 2019, when he reached Double-A in July of his full-season debut while striking out 10.0 and walking 3.0 per nine innings and allowing six home runs in 23 starts. He earned the Mets’ minor league pitcher of the year award. Scouting Report: The athletic, 6-foot-5 Smith has firm stuff but leans on deception and angle to succeed. He pitches at 90 mph from a slightly low three-quarters arm slot with plus arm speed and tailing life on his fastball. His low-80s slider features wide angle and high spin. The pitch is death on lefthanded hitters, who managed just .207 with three extra-base hits—all doubles—in 116 at-bats in 2019. Smith has developed a near-average changeup in pro ball. The Future: Smith is one of the hardest workers and fiercest competitors in the system. He met the challenge of Double-A a year into his pro career and should be ready for Triple-A—and beyond—by the second half of 2020. He profiles as a No. 5-type starter or quality bullpen arm.
BA Grade: 45. Risk: Medium Tool Grades: FB: 55. SL: 60. CHG: 40. CTL: 60. Track Record: Drafted 20th overall in 2017, Peterson spent the entirety of his third pro season in Double-A and made a career high 24 starts. He ranked fifth in the Eastern League with 122 strikeouts while placing among the Double-A leaders in groundball rate (52.6 percent) and swinging-strike rate (13.7 percent) among pitchers with 100 innings. Peterson logged extra work in the Arizona Fall League after the season. Scouting Report: Peterson offers proof that looks can be deceiving. At 6-foot-6, 240 pounds, he looks like a power pitcher but instead relies on working ahead, location and sequencing. Peterson is a strike-thrower who generates late swings and mis-hits thanks to the extension in is delivery that makes his 87-92 mph fastball look faster. His swing-and-miss slider has been his primary weapon dating back to college. The pitch has slurvy shape, late break and plus depth. Peterson’s below-average changeup is not a significant factor and is more of a show-me pitch. The Future: Peterson’s lack of fine command and sometimes questionable body language turn off some scouts, but he’s lefthanded, throws strikes and has a plus slider. He could begin getting looks at the back of the rotation beginning in 2020.
