RoboScout’s Top Fantasy Prospects At Every Level On June 1, 2025

Complex League Hitting

The top hitting performances for the Complex Leagues per RoboScout are:

	Name	Team	Age	wRC+	HR	SB	Robo	RoboCast
1	Rainiel Rodriguez	STL	18	227	7	1	100	100
2	Jose Anderson	MIL	18	204	3	3	78	78
3	Juneiker Caceres	CLE	17	151	0	4	76	76
4	Dauri Fernandez	CLE	18	189	1	5	74	74
5	Ching-Hsien Ko	LAD	18	214	1	2	73	73
6	Anderson Fermin	BOS	18	170	0	10	72	72
7	Stiven Martinez	BAL	17	131	1	2	69	69
8	Javier Sanchez	TEX	17	129	1	0	69	69
9	Kevin Garcia	MIL	17	133	2	0	69	69
10	Juan Ortuno	MIL	18	154	3	3	69	69

Shockingly, Cardinals catcher Rainiel Rodriguez didn’t homer over his 13 plate appearances this week, but he remains far and away the best hitter in the Complex Leagues with a lofty 227 wRC+

Dodgers outfielder Ching-Hsien Ko is this week’s biggest riser. RoboScout flagged the Taiwanese import last August when he showed a very patient approach and a knack for the barrel in his brief DSL debut. This week, Jesus Cano wrote about him as an ACL prospect making noise, showing off physicality and big power but still with the speed to handle center field.

Another name from RoboScout’s 2024 radar climbing the 2025 rankings is Brewers infielder Juan Ortuno, who ranked No. 11 in the DSL last year. This week, he homered and boosted his wRC+ from 137 to 154, pushing him into the top 10. Last year, Ortuno showed above-average contact skills and swing decisions but had just a 96 mph 90th percentile exit velocity. This year, he has three homers in 82 plate appearances—matching last season’s total in half the trips—suggesting 15-20 home run potential at peak. At just 5-foot-8, it’s probably safe to expect little more than that in the majors.

Complex Pitching

The top pitcher performances in the Complex Leagues per RoboScout are:

	Name	Team	Age	IP	K%	BB%	WHIP	ERA	GB%	Robo
1	Argenis Cayama	SFG	18	20.1	32.5%	7.5%	0.93	0.89	63.0%	100
2	Reinold Navarro	PIT	18	13	43.1%	17.6%	1.08	2.08	44.4%	99
3	Ethan Dorchies	MIL	18	17	33.3%	4.5%	0.76	2.12	33.3%	99
4	Jostin Florentino	CHC	20	21.2	37.4%	5.5%	1.15	3.74	40.8%	99
5	Jose Bello	SFG	20	12	47.7%	4.5%	0.67	0.00	52.4%	97

7	Nate Payne	MIA	19	10.2	41.0%	10.3%	0.84	2.53	26.3%	94
8	Jose Feliz	WSN	19	20.2	30.0%	5.0%	0.92	3.05	46.0%	93
9	Johnny King	TOR	18	8	38.7%	9.7%	0.75	0.00	69.2%	93
10	Ubaldo Soto	LAA	18	15.2	30.8%	10.8%	1.02	2.30	62.9%	92

After an eight-strikeout, one-walk, four-inning outing last week, Pirates lefthander Reinold Navarro jumps to No. 2 in the rankings after being unranked a week ago, underscoring just how volatile the Complex League remains early in the season. We highlighted the 18-year-old a few weeks back as a deep-league flier thanks to his high-IVB power fastball, which touched 96 mph last year. That evaluation still holds.

Giants righty Argenis Cayama remains the class of the level, armed with a mid-90s fastball, confident slider, and developing changeup. He’s keeping the ball on the ground at a 63% rate, and RoboScout sees him as having the best major league projection at the level (not including Travis Sykora’s lone Complex League start).

Low-A Hitting

The top hitting performances for Low-A per RoboScout are:

	Name	Team	Age	wRC+	HR	SB	Robo	RoboCast
1	Luis Pena	MIL	18	159	4	22	100	100
2	Eduardo Quintero	LAD	19	179	9	25	100	98
3	Jesus Made	MIL	18	138	4	21	90	88
4	A.J. Ewing	NYM	20	201	1	14	74	84
5	Caleb Bonemer	CHW	19	159	4	15	80	83
6	Andrew Salas	MIA	17	109	0	16	85	81
7	Javier Mogollon	CHW	19	176	4	12	82	79
8	Theo Gillen	TBR	19	162	4	13	83	79

10	Eduardo Tait	PHI	18	119	8	0	79	78
11	Sam Shaw	TOR	20	158	5	4	67	76
12	Konnor Griffin	PIT	19	141	8	23	74	75
13	Bryce Rainer	DET	19	142	5	9	70	75
14	Yasmil Bucce	BAL	20	167	4	2	63	74
15	Aroon Escobar	PHI	20	155	8	5	65	74
16	Victor Rodrigues	LAD	20	151	1	3	62	71
17	Axiel Plaz	PIT	19	130	8	1	67	70
18	Brailer Guerrero	TBR	19	143	4	6	65	70
19	Owen Carey	ATL	18	122	2	9	69	70
20	Alfredo Duno	CIN	19	138	4	4	67	69

With both players projected by RoboScout as above-average major league hitters with 20 home run, 20 stolen base potential, you can’t go wrong ranking Brewers prospect Luis Peña and Dodgers prospect Eduardo Quintero—as long as they’re first and second.

Red Sox corner infielder Freili Encarnacion hasn’t cracked the RoboScout chart yet this season, but he posted a 190 wRC+ in May with seven homers in fewer than 100 plate appearances. Last year, the then-19-year-old recorded a 107 mph 90th percentile exit velocity and a 115 mph max, flashing easy plus power. This season, he’s already hit two balls over 117 mph, including a single reportedly clocked at 120.6 mph. His strikeout rate is 21% on the year, though it dipped to 16.5% in May. He’s highly aggressive, chasing at a high rate, and owns just a 2% walk rate. The power is real, but the approach is what’s keeping him from flying up prospect boards.

Braves outfielder Isaiah Drake is on fire in May. While he doesn’t receive nearly as much fanfare, his surface-level stats closely mirror star Pirates prospect Konnor Griffin. A fifth-round pick in 2023, Drake was a raw, toolsy prep prospect with 80-grade speed and the ability to stick in center field. Here’s how their May performances compare:

Name	Age	PA	wRC+	ISO	HR	SB
Isaiah Drake	19	98	142	.193	3	9
Konnor Griffin	19	107	147	.160	3	12

With his tools, If he can keep up the bat-to-ball improvements that he’s begun to show, God’s plan will be for Drake to rise up the rankings.

19	John Holobetz	MIL	22	24	31.3%	5.1%	0.88	3.00	33.3%	74
20	Kash Mayfield	SDP	20	20.1	30.3%	10.1%	1.28	4.87	41.2%	74

David Shields climbs to the second spot after another excellent start. In three Low-A starts, the savvy lefty has a strikeout-minus-walk rate of 35.6% while keeping the ball on the ground at a 52% clip. He only has an 11% swinging strike rate, suggesting the strikeout rate will regress a bit, but RoboScout sees a midrotation starter with s sub-4.00 ERA.

Back in April, Geoff Pontes identified Rangers righty Caden Scarborough as a hidden gem after he came into camp more physical with better stuff than what he showed as a 2023 sixth-rounder out of high school. In May, he’s been one of the top performers still in Low-A, with a 40% strikeout rate and 6% walk rate over six starts. His 33% strikeout-minus-walk rate ranks behind only Trey Yesavage, Shields and Khal Stephen among Low-A pitchers age 23 or younger—though both Yesavage and Stephen have since moved up. The Rangers have had recent success with pitching development, and Scarborough may be their next breakout.

High-A Hitting

The top hitter performances for High-A per RoboScout are:

	Name	Team	Age	wRC+	HR	SB	Robo	RoboCast

It took until June, but Padres shortstop Leo De Vries has finally been unseated as the crown jewel of High-A. The 18-year-old struggled in May, posting a 74 wRC+, which is even lower than the 78 wRC+ Marlins prospect Andrew Salas put up in Low-A this month.

Tigers catcher Josue Briceño, a longtime RoboScout favorite, has been the hottest hitter in High-A. He owns a 237 wRC+ and seven home runs in his last 58 plate appearances, including a three-homer game on Thursday. Already a top 100 fantasy prospect, Briceno has a wide range of outcomes. If he can stick behind the plate, he likely ranks in the top 50. If he moves to first base, he probably drops into the lower quartile.

Mariners infielder Michael Arroyo, last year’s second-ranked RoboScout hitter, continues to climb after a two-homer week, moving from No. 20 to No. 16 in the rankings.

Athletics corner infielder Tommy White has hit four home runs in his last six games, spanning 22 plate appearances, pushing him onto the back end of the High-A rankings. A few weeks ago, Geoff Pontes identified White as a player showing marked improvement in contact rate, which has translated to a strikeout rate under 10% this season.

Blue Jays righthander Trey Yesavage made two more starts this past week and, despite carrying a 20% walk rate at High-A Vancouver, remains the top pitcher on the High-A list. When paired with his dominant Low-A performance, RoboScout sees Yesavage as a mid-rotation starter or better at peak. He also projects with more fantasy upside than Athletics lefty Gage Jump and Mets righthander Jonah Tong, despite being further from the majors.

Vancouver teammate Gage Stanifer also made two starts this week, striking out 14 and walking three. The 21-year-old righthander has a double-digit walk rate on the season, but his arsenal—a mid-90s four-seam fastball, a low-to-mid-80s bullet slider and a changeup with more than a foot of vertical separation—has missed plenty of bats in 2025. While his command still needs refinement to avoid a bullpen projection, RoboScout sees back-of-the-rotation potential based on surface performance.

Twins righthander Cole Peschl, a 15th-round pick out of Campbell in 2024, signed for $150,000 and leaned primarily on a solid slider, supported by a 92 mph fastball, a curveball and a changeup. In 2025, he’s thrown 26.1 innings at Low-A with a 33% strikeout rate, 8% walk rate and a groundball rate over 50%. Since earning a promotion to High-A Cedar Rapids, Peschl has made two starts without issuing a walk, while striking out 30% of batters and keeping a 65% groundball rate. His stuff isn’t overpowering, but the pitchability and results suggest he could reach a back-end starter ceiling—an excellent outcome for a modest signing.

Double-A Hitting

The top hitter performances in Double-A per RoboScout are:

	Name	Team	Age	wRC+	HR	SB	Robo	RoboCast
1	Sebastian Walcott	TEX	19	119	8	11	100	100
2	Jett Williams	NYM	21	150	4	16	91	98

18	Travis Bazzana	CLE	22	136	4	8	71	81
19	Diego Velasquez	SFG	21	124	1	7	72	80
20	Kahlil Watson	CLE	22	150	4	6	70	80

Well, well, well—look who’s at No. 20 on the list: old friend Kahlil Watson, now in the Guardians system. With a blend of power and speed, Watson is posting his lowest strikeout rate since his Complex League debut in 2021, down to a solid 23%. Still just 22 years old, RoboScout sees the newly minted outfielder as an above-average major league bat with 16–20 home runs and around a dozen steals. Here’s hoping the former first-rounder can swing his way back into prospect relevance.

While Padres shortstop Leo De Vries has cooled off in High-A, Rangers shortstop Sebastian Walcott homered twice this week for Double-A Frisco, boosting his season wRC+ to 119. Surprisingly, that still trails fellow 19-year-old Nelson Rada’s 135 mark this season. Walcott cemented his position at the top of the table for another week.

After Red Sox corner infielder Blaze Jordan—who we discussed last week and now promoted to Triple-A Worcester—perhaps no Double-A hitter has been hotter over the past month than Athletics first baseman Brennan Milone. Over his last 95 plate appearances, Milone posted a 180 wRC+ with seven home runs, earning a promotion to Triple-A Las Vegas. He’s long shown excellent swing decisions and above-average contact, though he’s never topped 106 mph in exit velocity over the past three seasons. Still, his barrel rates and launch angles have consistently outpaced league averages, allowing him to optimize contact quality despite limited bat speed. RoboScout sees a path to 20-plus home runs.

Braves outfielder Geraldo Quintero has quietly turned in a strong May in Double-A. The 23-year-old left fielder hit five home runs, stole six bases and posted a 184 wRC+ over 74 plate appearances. On paper, that’s 20/20 potential—but his exit velocities are well below-average and have been for years. He’s never eclipsed 99 mph in 90th percentile exit velocity across the past three seasons. Still, Quintero is maximizing his quality of contact with pulled fly balls and consistent barrel control. RoboScout remains skeptical, but he’s the kind of deep-league dart throw worth tracking. He’s sustained a projected 20-homer, 15-steal pace all season despite the red flags.

The most unexpected name on the Double-A list is Rockies righthander McCade Brown. A 2021 third-round pick out of Indiana, Brown sits in the mid 90s with a fastball that plays up thanks to above-average extension. He throws a firm mid-80s slider that can reach 89 mph, along with a curveball and changeup. Over 38 innings between High-A and Double-A, he’s posted an 11% walk rate, which puts him at some risk of a relief role. However, he’s averaging about four innings per outing and carries a 36% strikeout rate, offering hope he can stick as a starter. RoboScout projects a neutral-park peak of a 1.29 WHIP and 4.20 ERA.

While much of the Blue Jays’ pitching buzz has focused on Trey Yesavage and Khal Stephen, righthander Juaron Watts-Brown also deserves attention. After posting a 37% strikeout rate at High-A Vancouver, he earned a promotion to Double-A New Hampshire. His first two starts at the level haven’t matched his earlier dominance, but RoboScout still sees his four-pitch mix—including a 93 mph fastball with strong extension—as supporting a potential 25% strikeout rate in the majors, along with a sub-4.00 ERA and 1.20 WHIP. At worst, he profiles as a top-175 fantasy prospect.

Congratulations to Mariners shortstop Cole Young, who posted a 190 wRC+ in May with five home runs and four stolen bases, earning a promotion to the majors ahead of Roman Anthony and Jac Caglianone. While RoboScout doesn’t project more than 18 home runs or more than a handful of steals at peak, Young’s on-base ability could land him atop Seattle’s lineup—possibly as soon as this season.

Rockies shortstop Ryan Ritter remains red hot, slugging seven more home runs in his last 30 plate appearances to bring his season total to 16. If he keeps up this pace, Ritter may soon be knocking on Colorado’s door.

Ever since his days with the White Sox, Diamondbacks righthander Cristian Mena has been a RoboScout favorite and consistently young for his level. Now back in the majors in Arizona’s bullpen—for now—Mena has seen his stuff tick up in 2025. His four-seam fastball, which averaged 93.1 mph last season, is now sitting 94.6. His curveball is up from 83 to 87 mph and has boosted its whiff rate from 30% to 46%. His slider has morphed into more of a cutter, increasing from 85 to 86 mph and generating 48% whiffs, up from 38%.

Over his last three starts, Mena has posted a 30% strikeout rate, a 1.20 WHIP, and a 3.00 ERA while averaging five innings per outing in a tough home environment. He’s pushing back into top-100 fantasy prospect consideration, with RoboScout projecting him as a midrotation starter based on 44.2 innings of 2025 data. With Corbin Burnes possibly facing a significant injury, it wouldn’t be surprising to see Mena start for Arizona at some point this season.

On last week’s Baseball America Prospect Podcast, J.J. Cooper spotlighted Rays lefthander Ian Seymour, who promptly followed up with a 10-strikeout, no-walk performance over five innings. Despite lacking overpowering stuff, Seymour ranks third on RoboScout’s Triple-A list. His 91 mph fastball plays up with strong extension and a flat plane, producing a whiff rate north of 33% over the last two seasons. He now throws his changeup almost as often as his fastball, and even with the increased usage, it’s generating a 46% whiff rate—up from 45% last year. His cutter rounds out the arsenal as an average or better third offering. While a low 33% groundball rate caps some of his surface stats, RoboScout still projects Seymour as a solid back-of-the-rotation starter. A callup may not be far off.

Athletics righthander Jack Perkins also makes the list this week after striking out 30 batters in his last four starts. A popular redraft sleeper this spring, Perkins appears poised for a callup later this season. His arsenal includes a 96 mph fastball, an 85 mph slider with a 45% whiff rate, and a 91 mph cutter that bridges the two. Alongside Luis Morales (No. 18 on this week’s list) and Gage Jump in Double-A, RoboScout sees brighter days ahead for the A’s rotation in 2026 and beyond—even if it remains skeptical of 2025 risers J.T. Ginn and Jacob Lopez.

Happy bidding!
