The White Sox have designated outfielder Oscar Colas for assignment and claimed infielder/outfielder Greg Jones off waivers from the Rockies, per a team announcement. Chicago optioned Jones and righty Justin Anderson to Triple-A Charlotte. The Sox also reassigned infielders Bobby Dalbec, Tristan Gray and Chase Meidroth to minor league camp alongside righties James Karinchak and Steven Wilson.

Now 26 years old, Colas came to the White Sox with considerable fanfare. The Cuban-born slugger was touted as one of the more intriguing prospects on the 2020-21 and 2021-22 international amateur markets. He bizarrely (and frankly, unfairly) drew comparisons to Shohei Ohtani, of all players, for his plus raw power and because he’d dabbled in pitching during his time in Cuba and a brief foray into Japan’s Nippon Professional Baseball. Outlandish as that comparison was, it did set some unrealistic expectations among fans who were dreaming on Colas as a potential superstar.

Even before the White Sox signed him, Colas had signaled that he no longer intended to pitch and that he’d focus his efforts on his work as a position player. He formally signed with Chicago in Jan. 2022 for a reported $2.7MM bonus. Colas went on to tear through minor league pitching that season, slashing .314/.371/.524 with 23 homers across three levels. Strong as those rate stats were, his production came with some red flags. Colas spent the bulk of the season playing against younger and less experienced competition, and he rarely walked. His strikeout rates also climbed rapidly as he moved from High-A to Double-A to Triple-A.

The Sox gave Colas his big league debut in 2023, and he quickly looked overmatched. In 75 games and 263 plate appearances, he hit just .216/.257/.314 with a tiny 4.6% walk rate and a bloated 27.6% strikeout rate. Of the 328 big league hitters with at least 250 plate appearances in 2023, Colas chased balls off the plate at the 13th-highest rate, per Statcast, despite also turning in a well below-average contact rate on such swings. Only 39 of those 328 hitters had a lower overall contact rate than Colas.

For all of Colas’ big league struggles in 2023, he at least turned in a .272/.345/.465 line in Triple-A Charlotte. That was league-average production by measure of wRC+ — a testament to the hitter-friendly nature of the Triple-A International and Pacific Coast Leagues. Colas showed solid discipline in the minors, walking at a 9.2% clip against a roughly average 22.3% strikeout rate.

The 2024 season brought considerable regression. Colas hit only .246/.332/.400 in Triple-A. His 11% walk rate was an improvement, and his 23.1% strikeout rate effectively matched the prior season, but Colas’ power deteriorated. He also became increasingly prone to hitting grounders and harmless infield flies; nearly one-quarter of his fly balls in Triple-A last year registered as infield flies. That’s more than double the 10.3% MLB average. Despite the Sox fielding a historically bad team, they scarcely gave Colas a look; he logged only 38 plate appearances and hit .273/.368/.273 while fanning 10 times (26.3%). Spring training hasn’t done Colas any favors. He received only 18 official plate appearances and went 4-for-16 with seven strikeouts.

The White Sox will now trade Colas or place him on waivers within the next five days. Outright waivers are a 48-hour process, which could drag his stay in DFA limbo out to a maximum of one week. Though he was a touted prospect not long ago, Colas’ struggles and limited skill set might allow Chicago to keep him. Today’s front offices typically aren’t enamored of power-focused corner bats with questionable on-base skills and sub-par defensive acumen.

In Jones, the Sox will pick up one of the sport’s fastest players. The 27-year-old has only six MLB plate appearances to his credit — he went 1-for-6 with a homer for Colorado last year — but drew 80 grades for his speed as a prospect. Jones went 46-for-49 in stolen bases at the Triple-A level last year despite being limited to just 89 games by injury. He hit .267/.344/.453 with the Rockies’ top affiliate (99 wRC+).

Jones is in the last of his three minor league option years. The former Rays first-rounder has split the bulk of his pro career between shortstop and center field. He’ll give the South Siders some depth at both spots and would presumably be an option in the outfield corners or at second base and third base as well. The Rockies gave him 64 games in center, 16 at shortstop, eight at second base and four in right field last year.

Colorado picked Jones up in a March 2024 trade sending left-handed pitching prospect Joe Rock to the Rays. The Rockies are left without anything to show for that swap now, whereas Rock has blossomed into a nearly MLB-ready rotation prospect for Tampa Bay. Rock profiles as more of a back-end starter or multi-inning reliever than a top-of-the-rotation talent, but the swap has clearly worked out in the Rays’ favor to this point.
