Miguel Vargas changed his stance at the plate, and it changed his season.
Vargas was the biggest breakout star on the Chicago White Sox, and it all started with a subtle adjustment entering 2026. The mechanical change that sparked it all was relatively simple.
He adopted a more upright stance and eliminated the scissor kick that had caused him to drift through the ball. In the process, he found a level of balance and bat speed that had previously eluded him, unlocking the best season of his career.
According to MLB Network’s Tom Verducci, that seemingly simple adjustment was at the heart of Vargas’ breakout. The changes have helped him stay more balanced and keep his head over his body as he brings the bat through the zone. The result has been a noticeable jump in bat speed, from 70 mph to nearly 74 mph.

The results were impossible to ignore.
Through his first five MLB seasons, Vargas had never posted an OPS higher than .717 or reached the 20-home run mark in a single season. Vargas not only surpassed both of those marks, but also transformed himself into one of the best third basemen in baseball.
His 5.4 WAR ranked third among MLB third basemen, trailing only Junior Caminero and Alex Bregman. He earned his first All-Star selection, homered in the All-Star Game and capped his breakout season by setting career highs in home runs, RBIs, runs scored and OPS.
Vargas was the driving force behind the White Sox offense, leading the team with 93 RBIs, 106 runs scored and an .837 OPS while finishing second on the team with 33 home runs.
But the most remarkable part of Vargas’ transformation was what happened beneath the surface. He raised his walk rate from 9.8% to 14.5%, putting him in the top 4% of MLB hitters. He also ranked in the top third of the league in nearly every major underlying metric, including the top 10% in Batting Run Value, expected slugging percentage, sweet-spot rate, and chase rate.
Those numbers suggest Vargas’ breakout was about far more than simply hitting for more power. At 26, he has come of age not only as a player, but as a professional. After considering walking away from baseball following a disastrous 2024 campaign, Vargas revamped his approach at the plate and emerged as the driving force of the White Sox offense.
That transformation has extended beyond the batter’s box. Vargas’ relationship with rookie Munetaka Murakami has been well documented this season, with the two becoming close friends. Their friendship has not only helped Murakami adjust to life in the majors, but also helped Vargas come out of his shell.
Vargas may not be the most vocal player on the team, but he has increasingly led by example. The once-reserved infielder has embraced a larger role and developed into one of the most important pieces of Chicago’s young core.
