2026 DRaysBay Community Prospect List: Vote for No. 17

Nathan Flewelling, C19 | L/R | 6’2” | 200A | .229/.393/.336 (126 wRC+) 439 PA, 6 HR, 9 SB, 20.3% BB, 27.6% KA+ | 22 PA, 4 H, 5 BB, 6 K

The 94th overall pick from 2024, Flewelling made his debut at 18 years young and caught a full season (75 C, 26 DH), plus a five game cup of coffee (3 C, 2 DH). Taking the longview, he could grow into 50-60 grade power with 50 grade defense, which makes him one to follow. His plus zone awareness at the plate offsets his lagging contact, and most importantly for the position his ability to call games and frame pitches are already plus. A strong season with the bat at High-A could vault him into Top-100 consideration.

Made a judgement call in Testers and am adding Cooper Flemming from the 2025 draft. It would be helpful for folks to add votes in Testers if you have an opinion on the next candidate profile! And remember, if you don’t see who you want to vote for, put them in Others.

Jackson Baumeister, RHP23 | 6’4” | 224AA | 4.62 ERA, 4.15 FIP (15 GS) 62.1 IP, 19.5% K, 9.6% BBAFL | 6 ER (1 HR), 9.0 IP (4 G, 3 GS), 10 K, 9 BB

A shoulder injury derailed what should have been Baumeister’s coming out party, as his previously plus breaking ball was expected to carve up Double-A. After a tough start to the year and two months on the sidelines, Baumeister returned in August and salvaged the season with a brilliant finish. The tough luck continued, however, in the Arizona Fall League, where a line drive struck him in the head, but he escaped without significant injury. Currently, Baumeister has taken on a fastball/slutter profile, with a slow curve in his back pocket, and has shown teachability and pitchability over the years. The former Seminole currently thrives on his frequently used major league fastball that may be better challenged by a promotion to Triple-A.

Homer Bush Jr.24 | R/R | 6’3” | 215AA | .301/.375/.360 (122 wRC+) 546 PA, 0 HR, 57 SB, 8.8% BB, 17.9% K

Acquired in the 2024 Jason Adam trade, the starting center fielder at Double-A passed the test of advanced pitching, but just barely. He lacks in-game power due to a lack of use of his lower half in his swing, and he whiffed more often than you can for long term success with a low-power approach. His calling cards are Rays-grade defense and plus-speed, having notably swiped 57 bags in back-to-back seasons.

Cooper Flemming, SS19 | L/R | 6’3” | 190

One of the best high school bats in the 2025 draft, Flemming surprisingly fell into the Rays laps in the second round. He has a too-quiet swing that lacks the load necessary to hit for power, but he’s historically compensated for that with a high contact rate that would have rated him as first round material if his defense projected to stick. The Rays were able to convince him to forgo an education at Vanderbilt by going above slot ($2.3m, Comp-A money).

Brailer Guerrero, OF20 | L/R | 6’1” | 215A | 249.338/.399 (119 wRC+) 222 PA, 6 HR, 9 SB, 11.3% BB, 29.3% KAFL | 2 H, 0 HR, 2 SB, 3 BB, 16 K, 29 PA

Good news: the $3.7 million 2023 signee made the leap out of the complex league in his final teenage season. Bad News: He was injured yet again, with hamstring and knee injuries limiting him to 51 games for Charleston. The Rays tried to make up for lost time with an aggressive assignment to the AFL that resulted in only two hits in 29 plate appearances. He makes loud contact from a quick, quiet swing which he pre-loads by reaching back for even more power. He appears to make early decisions to swing, leading to a bit extra whiffs against anything off-speed, but that could easily clear up with some consistent playing time.

Trevor Harrison, RHP20 | 6’4” | 225A | 2.61 ERA, 3.26 FIP, 82.2 IP (17 GS), 22.4% K, 10.7% BBA+ | 3.33 ERA, 4.26 FIP, 24.1 IP (5 GS), 23.8% K, 12.4% BB

Harrison entered the season as Baseball America’s top pitcher in the system thanks to a cleaned up delivery and high heat. He ran into some bumps in the road by running up his pitch count against batters, but he still made it over 100 innings in 22 starts. A power pitcher through and through, his hard slider flirts with cutter classification and could evolve into two distinct pitches down the road. It will be interesting to see how his change up plays as he’s challenged at higher levels, but for now he has premium stuff and the upside of a rotation anchor. (video)

OF Victor Mesa Jr.24 | L/L | 5’11” | 195AAA (MIA) | .301/.368/.510 (136 wRC+) 171 PA, 7 HR, 4 SB, 9.9% BB, 16.4% KMLB (MIA) | 6 H (1 HR), 5 BB, 5 K (81 wRC+) 38 PA

This Cuban power bat already made his major league debut with Miami last year after bouncing back from a spring hamstring injury, and was dealt to the Rays in February. He profiles as a fourth outfielder but has an option remaining, so the organization may send him down for regular playing time and one last chance for something more in development. If not, he’s a center field capable on defense, which goes a long way for a platoon bat. In the running for the nicest guy in baseball.

Tre’ Morgan, 1B/LF23 | L/L | 6’0” | 215AAA | .274/.398/.412 (119 wRC+) 402 PA, 8 HR, 8 SB, 15.9% BB, 19.2% K

Morgan continued to hit without power in 2025, a great discouragement for some evaluators, but his present 50-grade hit tool and feel for the zone allow a major league projection. He continued his improved, quieter two-strike approach in 2025 that built on his success retooling his swing in the AFL last year. The Rays gave Morgan 14 starts in Left Field last season, and Baseball America called the defense “playable,” but his value is tied to his plus-plus defense at First.

Aidan Smith, OF21 | R/R | 6’2” | 190A+ | .237/.331/.388 (114 wRC+) 459 PA, 14 HR, 41 SB, 11.5% BB, 31.2% K

Acquired in the Arozarena trade, Smith became the prince who was promised, a five tool athlete with a strong bat, good face, and a preternatural glove in center field. That promise unraveled a bit in 2025, with his strikeout rate rocketing nine percent and his power stroke faltering after facing harder velocities in High-A, causing both his hit and power grades to drop into the 40’s. It was a full transformation into a “center field” profile, but with his ceiling that’s not a compliment. He plays with a fire, but the dip in contact rate left some evaluators feeling burned.

Brayden Taylor, 2B/3B24 | L/R | 6’0” | 180AA | .173/.289/.286 (77 wRC+) 437 PA, 8 HR, 17 SB, 14% BB, 27.7% KAFL | .264/.400/.472 (.384 wOBA) 65 PA, 1 HR, 5 SB, 12 BB, 19 K

Taylor entered 2025 as a top-100 prospect after demolishing High-A (154 wRC+), and left 2025 as an afterthought on prospect lists, although he was selected as an Arizona Fall League “Fall Star” in between, where he worked to keep his chase rate low and his hard hit rate high. The juice must have been worth the squeeze, as the Rays have elected to invite Taylor to major league Spring Training this year.

Jose Urbina, RHP20 | 6’3” | 180A | 2.05 ERA, 3.58 FIP, 92.1 IP (19 GS), 26.4% K, 8.2% BBA+ | 2 ER (2 HR), 4.0 IP (1 GS), 5 K, 0 BB

Good pitchers grow and adjust, and Urbina has done that consistently at an age young for his level. Physically he has grown in strength, sitting at 96 with the fastball after flashing high octane in 2024, and technically he has grown, refining his dialed up slider and his two-plane curveball into complementary pitches — which lack plus command but are thrown with feel. He shouldered a starter’s workload at 19, and was awarded one additional start at High-A, where he allowed two solo shots and struck out five. Overall, the age, body, and body of work have him on the trajectory of top prospect lists in the near future.
