The Arizona Fall League gave the Rockies a couple of prospects a chance to make noise, and Jared Thomas and Fidel Ulloa both took advantage.
Thomas, the organization’s No. 10 prospect, put together the kind of run that can change how people talk about a player. The 23-year-old from Austin, Texas, hit .305/.406/.573 with a .979 OPS in 24 games, and he finished as one of the hottest bats in the league.
The left-handed hitter, drafted by Colorado in the second round of the 2024 MLB Draft out of the University of Texas, showed off a little of everything in Arizona. He piled up triples, home runs, doubles and hits, and in a twist that stands out, he had more triples than doubles, finishing with 6 triples and 4 doubles.
Thomas was especially productive at Salt River Fields, where he kept stacking quality at-bats and extra-base hits. He leaves the fall league with momentum and a lot of eyes on him heading into next season.
Ulloa, meanwhile, turned in a dominant stretch that was easy to miss if you weren’t paying attention. The right-handed reliever went 2-0 in 8 games and did not allow an earned run.
He gave up only 4 hits, struck out 11 and finished with a 0.82 WHIP, putting him among the league’s best in both run prevention and traffic suppression. He was one of 12 pitchers this fall with an ERA of zero and one of eight with a WHIP under 0.85.
That work earned Ulloa a spot on the National League’s Fall Stars Game roster. The Rockies drafted him in the 7th round of the 2024 MLB Draft after one season at LSU.
For Colorado, the takeaway is simple: two lower-profile prospects went to Arizona and looked like they belonged. Thomas flashed impact with the bat. Ulloa kept hitters quiet every time he took the mound.
