Every MLB Team's Biggest Prospect Standout from the 2023 Arizona Fall League | News, Scores, Highlights, Stats, and Rumors

Arizona Diamondbacks: 3B Ivan Melendez

Stats: 97 PA, .229/.340/.386, 19 H, 8 XBH (2 HR), 13 RBI, 12 R

Melendez won 2022 Golden Spikes Award honors when he hit .387/.508/.863 with 32 home runs and 94 RBI in 67 games at the University of Texas. The risk of a right-handed hitting prospect with limited defensive value dropped him to the second round in the 2022 draft, but he posted a .923 OPS with 30 home runs in just 96 games during the regular season.

Colorado Rockies: IF/OF Sterlin Thompson

Stats: 95 PA, .338/.460/.475, 27 H, 9 XBH (0 HR), 13 RBI, 15 R

The Rockies were loaded with standout AFL performers, and there were a handful of players who could have been the pick here. Former first-round pick Benny Montgomery (94 PA, .333/.436/.500, 6 XBH, 10 SB) also looked good at the plate, while Alec Barger (8 G, 0.96 ERA, 13 K, 9.1 IP), Juan Mejia (8 G, 3 SV, 2.16 ERA, 16 K, 8.1 IP), Jaden Hill (11 G, 3.18 ERA, 13 K, 11.1 IP) and Case Williams (6 GS, 3.18 ERA, 1.24 WHIP, 17.0 IP) all shined on the mound.

Los Angeles Dodgers: LHP Ronan Kopp

Stats: 7 G, 1.13 ERA, 1.13 WHIP, 6 BB, 15 K, 8.0 IP

A 6'7", 250-pound left-hander with a fastball that touches 99 mph and a wipeout slider, Kopp has the stuff to be an impact arm out of the Dodgers bullpen. His size contributes to some inconsistency with his mechanics and spotty command, but he struck out 15 of the 32 batters he faced in the AFL after tallying 107 strikeouts in 72.1 innings during the regular season.

San Diego Padres: OF Jakob Marsee

Stats: 118 PA, .391/.508/.707, 36 H, 18 XBH (5 HR), 20 RBI, 25 R, 16 SB

The AFL leader in hits (36) and OPS (1.215), Marsee boosted his prospect stock more than perhaps any other player in this year's AFL class. The 22-year-old hit .345/.467/.550 with more walks (47) than strikeouts (33) for Central Michigan before going in the sixth round of the 2022 draft, and his offensive polish should help him move quickly through the minors.

San Francisco Giants: OF Carter Howell

Stats: 17 G, 61 PA, .273/.344/.527, 15 H, 6 XBH (3 HR), 6 RBI, 11 R

Undrafted out of D-III Augustana University (South Dakota) in 2022, Howell hit .295/.369/.442 with 26 doubles, eight triples, 10 home runs, 59 RBI and 14 steals in 119 games between Single-A and High-A to put himself on the prospect map. His AFL performance is another step in his stock rising.
