The Chicago White Sox completed one of the most dramatic turnarounds in MLB history in 2026, clinching a playoff berth just one year after finishing 60-102 and two years after setting the modern-era record with 121 losses.

The turnaround was not caused by one blockbuster acquisition. A young roster developed much faster than expected, several returning players made significant offensive improvements, Japanese slugger Munetaka Murakami gave the lineup a legitimate middle-of-the-order threat, and manager Will Venable helped turn a rebuilding club into a contender.
How Bad Were The White Sox Before 2026?
The numbers put the turnaround in perspective. Chicago lost at least 100 games in three consecutive seasons:
2023: 61-101
2024: 41-121
2025: 60-102
The 121 losses in 2024 were the most by an MLB team in the modern era. Even after improving by 19 victories in 2025, the White Sox still finished last in the American League Central. [White Sox]
That meant Chicago entered 2026 having gone 162-324 over the previous three seasons, a .333 winning percentage.
The White Sox were not widely expected to end the rebuild in 2026. Their objective entering the season was largely to continue developing a young core that included Colson Montgomery, Kyle Teel, Edgar Quero, Chase Meidroth, Grant Taylor and Shane Smith. [MLB]
What Changed For The White Sox In 2026?
The biggest difference was that several parts of Chicago’s rebuild began producing at the major-league level at the same time.
Instead of relying primarily on veterans while waiting for prospects to develop, the White Sox received meaningful production from young players already in the majors and continued promoting talent from a farm system rebuilt during the previous losing seasons.
Chicago’s position players were among the youngest groups in baseball early in the season, with a playing-time-weighted average age of approximately 26. [MLB]
The organization also supplemented that young core rather than replacing it. The most important offseason addition was Murakami, while the White Sox also added players including Austin Hays, Seranthony Domínguez, Sean Newcomb and Jordan Hicks. [MLB]
How Important Was Munetaka Murakami?
Murakami provided something the rebuilding White Sox badly needed: established power in the middle of the lineup.
Chicago signed the Japanese slugger to a two-year, $34 million contract before the season. There were questions about how his power would translate to MLB pitching and whether his strikeout rate would become a problem, but he quickly became one of the American League’s most dangerous home-run hitters. [MLB]
By late April, Murakami had already hit 12 home runs. He continued to be a major presence in the lineup even after missing 35 games with a Grade 2 hamstring strain. [MLB][MLB]
His impact also changed the structure of the lineup. Opposing pitchers could no longer work through Chicago’s order without facing an established power threat capable of changing a game with one swing.
How Did Miguel Vargas Become One Of Chicago’s Best Players?
Miguel Vargas’ breakout was another major reason Chicago improved so quickly.
Vargas had been part of the White Sox team that lost 121 games in 2024 after arriving from the Los Angeles Dodgers in the three-team trade that sent Michael Kopech and Tommy Edman out of Chicago. By 2026, he had developed into one of the most productive hitters on the roster.
By early June, Vargas led primary MLB third basemen in home runs, RBIs, runs and walks while carrying an .859 OPS. [MLB]
One measurable difference was his bat speed. MLB reported that Vargas increased his average bat speed from 70.6 mph to 73.7 mph, moving from the 25th percentile to the 70th percentile. [MLB]
That improvement lasted throughout the season. Vargas hit his 33rd home run on September 19 as Chicago fought for its playoff position. [Reuters]
Did The White Sox Change Their Hitting Approach?
Yes. One of the less obvious parts of the turnaround was an organizational effort to increase bat speed.
Chicago had the slowest average bat speed in MLB in 2025 at 70.9 mph. General manager Chris Getz and director of hitting Ryan Fuller implemented an offseason training program using weighted bats and other methods designed to increase swing speed without requiring hitters to completely rebuild their mechanics.
By 2026, Chicago’s average bat speed had moved much closer to the MLB average, while the offense became one of the league’s better power-hitting groups. Vargas was one of the most visible examples of the improvement. [Wall Street Journal]
How Did The White Sox Rebuild Their Young Core?
The terrible seasons also gave Chicago opportunities to accumulate and develop young talent.
Colson Montgomery developed into a major source of power. Catchers Kyle Teel and Edgar Quero reached the majors. Pitchers Sean Burke, Shane Smith, Noah Schultz and others gave the organization young arms, while prospects including Braden Montgomery and Sam Antonacci eventually contributed to the 2026 club.
By the 2026 All-Star break, Colson Montgomery led the team with 23 home runs, while Vargas, Murakami and Tristan Peters were selected to represent Chicago at the All-Star Game. [MLB]
Instead of one prospect carrying the rebuild, Chicago suddenly had young players contributing throughout the roster.
What Did Will Venable Change?
Venable was hired after the disastrous 2024 season and became the 44th manager in franchise history. His first White Sox team still lost 102 games in 2025, but there were signs of improvement beneath the final record.
Chicago played better during the second half of 2025, including a 25-31 stretch following the All-Star break as younger players received more major-league experience. [MLB]
That development carried into 2026. By the All-Star break, Chicago had avoided any losing streak longer than three games, an important difference for a team that had routinely endured prolonged collapses during the previous three seasons. [MLB]
Did The White Sox Make Trades At The Deadline?
Chicago entered the season as a rebuilding team but found itself in the unusual position of becoming a buyer during the summer.
One addition was center fielder Brenton Doyle, acquired from the Colorado Rockies in August for pitcher Mason Adams and infielder Carlos Vielma. [White Sox]
At the same time, general manager Chris Getz resisted dismantling the farm system simply because the club had unexpectedly entered the playoff race. Before the deadline, MLB reported that Chicago regarded players such as top prospect Caleb Bonemer and Braden Montgomery as important pieces of its longer-term plans. [MLB]
Were The 2026 White Sox Just Lucky?
Their underlying numbers suggested the improvement was more than simply winning an unusual number of close games.
On September 21, Chicago was 80-76 with 733 runs scored and 691 allowed, a positive run differential of 42. Its expected record based on those runs was 82-74. [MLB]
That was a major distinction from a rebuilding team merely surviving on one-run victories. Chicago was generally scoring more runs than it allowed over the course of the season.
How Did The White Sox Clinch The 2026 Playoffs?
The White Sox officially completed the turnaround on September 24 with a 9-1 road victory over Kansas City.
Chicago immediately took control, scoring three runs in the first inning and three more in the second. Vargas drove in runs in both innings, while Kyle Teel later hit a solo home run. David Sandlin allowed only one run over six innings. [AP]
The win improved Chicago to 82-77 and guaranteed the White Sox at least an American League Wild Card berth. It also marked their first postseason appearance since winning the AL Central in 2021. [MLB]
Chicago was still competing with the Cleveland Guardians for the AL Central championship after clinching its postseason berth, so its exact playoff position had not yet been determined. [MLB]
How Historic Is The White Sox Turnaround?
No previous MLB team had reached the postseason after losing at least 100 games in each of the previous three seasons. In fact, before Chicago’s run, no club had made the playoffs immediately after consecutive 100-loss seasons. [MLB]
Only three teams had previously reached the postseason one year after losing 100 games: the 2017 Minnesota Twins, the 2020 Miami Marlins and the 2024 Kansas City Royals. [Chicago Tribune]
The White Sox did it after three consecutive seasons of 101, 121 and 102 losses.
What looked like a long-term rebuild therefore accelerated dramatically. Murakami supplied immediate star-level power, Vargas and other returning players improved, prospects developed into major-league contributors, the organization’s revamped hitting program produced results and a roster built primarily for development turned into a playoff team much sooner than expected.
