The next installment of our series looking into breakout stories from the 2026 MLB season focuses on White Sox infielder Miguel Vargas.

This past season, Miguel Vargas was one of six hitters to rack up at least 100 walks this season. And out of that bunch, he was one of four to hit at least 30 home runs. That’s how good of a year it was for Vargas, who turned into an All-Star and a key reason why the White Sox made it back to October in 2026.

Making the most of a second chance

Over two years ago, Miguel Vargas was acquired by the White Sox in a three-team trade that most famously sent Tommy Edman to the Dodgers. Vargas was once a top prospect in the Los Angeles system but didn’t hit well in his brief MLB stints with the club. Coupled with the fact that he was blocked by Freddie Freeman and Max Muncy, he was expendable.

That move worked for the Dodgers. After all, Edman was on the Dodgers’ two title teams in 2024 and 2025. But it also worked for the White Sox, as the club found a controllable player who became an All-Star two years later.

His first full season in Chicago was fine overall. Vargas slashed .234/.316/.401 with 16 home runs and 50 extra-base hits. But in 2026, that next step was taken forward.

Vargas slashed .250/.363/.474 with career-bests in home runs (33), walks (101), plus extra-base hits (65).

Yes, adjustments

Like several breakout hitters we’ve profiled this fall, Vargas did make a significant adjustment to his stance. In 2025, which was Vargas’ first full season in Chicago, the corner infielder was more crouched, bringing the hands back and up while loading up.

But in 2026, a little more compact and upright.

Another adjustment had less to do with his stance, and more to do with his tendencies at the plate. Simply put, he expanded less on fastballs, four-seamers, and cutters in particular, plus a slight decrease on changeups.

The result?

Well, as expected, a big jump in Barrel%.

He doubled his Barrel% against sliders in two years, and that rate against sweepers was over 15% in 2026, well beyond where things were one year earlier.

Vargas hammered mistake-breaking balls but also fastballs at a pretty good clip, too. Take a look at the AVG chart by zone and against four-seamers from the 2026 season. While up in the zone wasn’t a place that resulted in a ton of hits, the middle of the plate and right inside on Vargas was a no-go zone for pitchers.

That was a change from the 2025 season.

When putting everything together, Vargas became the complete player. He always had the good eye in the Minors but trying to stay composed and work through things at the MLB level are two different things. When Vargas was with the Dodgers, there was no room for error. But when he arrived in Chicago, that became a different story.

Looking ahead

In some respects, Vargas was the engine of the White Sox’s offense in 2026. He got on base, slugged, and did everything needed of an All-Star third baseman. Because of that, it’s not a shock that the Sox were able to make it back to the postseason in 2026.

If the White Sox want sustainable success in 2027 & beyond, Vargas is going to be a key component of it.
