Vasil did not factor into the decision in Sunday's 7-5 loss to the Royals, allowing two runs on five hits and one walk with one strikeout over 3.1 innings.

EDGE Analysis

Vasil threw 33 of 50 pitches for strikes but managed just two whiffs in his first major-league start. The rookie has yet to allow more than two earned runs in any of his 19 outings this season and now sports a 2.18 ERA, 1.26 WHIP and 28:22 K:BB across 41.1 innings. If he gets another turn in the rotation, it would likely come on the road against the Rangers next weekend.

Vasil will start Sunday against the Royals, Kyle Williams of the Chicago Sun-Times reports.

EDGE Analysis

Vasil has worked multiple innings as a reliever throughout the season, and has thrown 9.2 consecutive scoreless frames across his last three outings. He's also maintained an impressive 10:2 K:BB in that span, so he should be able to work relatively deep into Sunday's matchup, if he remains effective.

Vasil didn't factor into the decision Wednesday against Detroit, allowing two hits and no walks with three strikeouts over 3.2 scoreless innings.

EDGE Analysis

Vasil followed opener Jared Shuster, who allowed four runs in his lone inning of work, and steadied the ship for the White Sox. The outing marked Vasil's third consecutive scoreless appearance, each of which lasted at least three innings. The 25-year-old rookie has been great to start 2025, owning a 1.89 ERA across 37 innings, though he could improve upon his 27:21 K:BB.

Vasil picked up the save in Wednesday's 4-2 win over the Reds, allowing one walk with no strikeouts over a scoreless ninth inning.

EDGE Analysis

Vasil has been a multi-inning reliever in 2025, but after tallying a 1.88 ERA through 24.0 innings to open his rookie season, the White Sox opted to give him a try in the ninth inning. He cashed in on the opportunity, logging the first save of his career. Considering the White Sox's lack of reliable arms, Vasil could continue to see save chances. However, those are expected to be few and far between.

Vasil (1-1) allowed one walk and no hits with zero strikeouts across 2.1 scoreless innings to earn the win Sunday against the Astros.

EDGE Analysis

Vasil was claimed off waivers just before Opening Day and has served in a multi-inning relief role to begin the campaign. He has just a 13:12 K:BB across 19.2 innings, though he has surprisingly maintained a 0.92 ERA and 1.07 WHIP. Those results look unlikely to continue, but Vasil has been a key to the team's bullpen.

Vasil was claimed off waivers by the White Sox on Sunday, Anthony DiComo of MLB.com reports.

EDGE Analysis

Vasil was selected by the Phillies during the Rule 5 Draft this offseason, but he was quickly traded to the Rays. Tampa Bay elected not to keep him, however, and Chicago then put in a waiver claim. Vasil, who had a 6.04 ERA over 134 innings at the Triple-A level last year, will need to spend the full season in the majors with the White Sox, or he'll be offered back to the Mets.

The Mets promoted Vasil from Single-A St. Lucie to High-A Brooklyn on Monday.

EDGE Analysis

Vasil will move up a level after he dazzled at Single-A with a 1.80 ERA, 0.97 WHIP and 37:11 K:BB across 35 innings. The 22-year-old righty limited opposing hitters to a .183 average.
