The White Sox are no longer playing baseball in 2026, but the Postseason continues nonetheless. Four teams remain, with the Dodgers and Brewers squaring off in a rematch of the 2025 NLCS, and the Guardians and Rays butting heads in the American League. It’s nearly impossible to make it to the Championship Series without a great deal of talent on your roster, and the rosters of the remaining teams feature a couple of familiar names. Here are a pair of former White Sox players who are still alive in the MLB Postseason and competing for a World Series.
1B Andrew Vaughn
A former third overall pick of the White Sox, Andrew Vaughn’s development was stunted by the COVID-shortened 2020 season and injuries that necessitated his expedited call-up to the big leagues. Vaughn played 55 minor league games in 2019, reaching the High-A level before the 2020 minor league season was cancelled. When play resumed in 2021, Vaughn seemed likely to begin the year in Triple-A, but a preseason injury to Eloy Jimenez inspired the White Sox to put Vaughn on the Opening Day roster in left field, a position he’d never played before at the professional level. Vaughn posted a .705 OPS and hit 15 home runs in his Rookie season, but never quite took the step forward the White Sox hoped he would, even after moving back to his natural position of first base. Vaughn was off to a rough start in 2025, with a .532 OPS in 48 games, before the White Sox dealt him to Milwaukee for righty Aaron Civale.
It turns out a change of scenery was what Vaughn needed. He posted an .868 OPS in 64 games down the stretch in 2025 and contributed heavily to their NLCS run. An early season injury got Vaughn off to a delayed start this season, and he mostly served as a platoon partner for Jake Bauers upon his return, but he’s continued to post strong offensive numbers since leaving the White Sox. In three games so far this Postseason, Vaughn is 2-for-5 with a double and a walk. He’ll likely continue to see regular at bats against left-handed pitchers as the Brewers try to take down the two-time defending champions.

LHP Cam Booser
Cam Booser wasn’t on the White Sox for long, but his impact was felt over the short time he was in Chicago. Unfortunately, it wasn’t in a good way. The White Sox acquired Booser in an offseason trade with Boston before the 2025 season, sending young right-hander Yhoiker Fajardo to the Red Six in exchange. Booser had a long path to the big leagues that included multiple injuries and off-field struggles, but finally reached the majors for the first time in 2024 with Boston, where he posted a 3.38 ERA in 43 games. With the White Sox, however, things didn’t go as smoothly. Booser struggled to a 5.52 ERA in 39 games with Chicago in 2025, and he spent the majority of the season floating between Chicago and Charlotte before being non-tendered in the offseason. Booser signed a minor league deal with the Rays, and as they often do, they’ve turned him into a truly dominant reliever.
In 42 games this season, Booser posted a 1.98 ERA, and he’s fired two scoreless innings in three Postseason outings for the Rays so far this October. In Booser, who is under team control until 2031, the Rays hope they’ve found a controllable reliever to be a piece of their bullpen moving forward, and it’s a tough break for the White Sox after letting him go. Now he’ll have a chance to add a World Series ring to his accolades.
