It was a solid season for the ACL White Sox, who finished 2025 with a 33-27 record and a +26 run differential. And run prevention was the key: The ACL White Sox only allowed 275 runs, which was No. 3 out of 15 teams in the Arizona Complex League. Their record was enough to tie them for the lead in the West Division, but the division title went to the ACL Rangers after the tiebreaker. The ACL White Sox finished strong, winning seven of their last 11, but it was not quite enough to take the division.
Adrian Gil, 19, a first baseman and catcher, was one of the major sparkplugs for the ACL White Sox. Gil played in 55 of the team’s 60 games, posting a .246/.364/.448 slash line and swiping 18 bases in 23 attempts (78.3%). Gil finished with seven homers (tied for the team lead) and 41 RBIs (led the team). He also shifted to catcher for 15 games, playing behind the plate for the first time in his career, an unusual position addition.
Gil was rewarded for his strong performance by being promoted to Kannapolis on July 25.
Center fielder Marcelo Alcala, 19, was also a reliable batter, slashing .233/.325/.479 in 42 games and tying Gil for the team lead in homers. Alcala was also incredibly efficient on the bases, as he stole 14 bases in 15 attempts (93.3%). During his young career, Alcala has been very consistent, posting an .825 OPS in 2023 and .810 OPS in 2024 with the DSL White Sox. This year, Alcala was nearly identical with the ACL White Sox, posting an .804 OPS. In the process, Alcala boosted himself to No. 28 on MLB Pipeline’s Top 30 White Sox prospect rankings.
Left fielder Albertson Asigen, 23, was a terrific hitter across his 40 games with the ACL White Sox. Asigen slashed .306/.447/.477 and was 13-for-18 (72.2%) on stolen bases. Asigen easily led the team in OPS among players with at least 100 at-bats. However, he was in Low-A all last season and played 2025 more than three years older than his level, so take this success with a grain of salt.
On the other hand corner outfielder Christian Gonzalez, 18, got a rare promotion from the DSL to the ACL late into the ACL season, but he made his time count. Gonzalez was on a heater before the promotion, and he did not slow down much afterward. In his 12 games in the ACL, Gonzalez slashed .381/.435/.500, and he was certainly a reliable batter down the stretch.
On the pitching side, there were many impressive individual performances, which is no surprise, considering how few runs the staff allowed. One of those performances came from starter Mathias LaCombe, 23, who earned a promotion to Kannapolis on July 18. Before that promotion, LaCombe posted a 2.52 ERA in 35 2⁄3 innings, leading the team with 50 strikeouts while only issuing 11 walks. Opposing hitters only slashed .184/.295/.288 against LaCombe, who posted a 0.95 WHIP. LaCombe is No. 27 on MLB Pipeline’s Top 30 White Sox Prospect rankings, the highest of anyone with significant playing time on the ACL White Sox this season.
Fabian Ysalla, 20, finished No. 2 on the team in strikeouts (40) and led the team in innings pitched (49). Ysalla posted a 2.02 ERA to lead the way among ACL White Sox starters, and there was some serious competition for that distinction.
Among relievers, Jake Curtis, 23, could not have been much better, and he earned a promotion to Kannapolis on July 3. Before the promotion, Curtis opened the season with 22 excellent innings in the ACL, posting a 2.95 ERA and a 1.09 WHIP. Curtis averaged 11.3 strikeouts per nine innings, and he only issuing 2.8 walks per nine.
