Chicago White Sox slugger Munetaka Murakami hit his 20th home run of the 2026 season on Wednesday, marking a historic start to his Major League Baseball career. Through just 55 games, the 26-year-old has joined elite company, tying the all-time rookie record for home runs hit before the month of June.
A Historic Pace in Chicago
The arrival of Munetaka Murakami in Chicago has fundamentally altered the trajectory of the White Sox. After enduring three consecutive seasons of more than 100 losses, the team currently sits at 28-27, holding a wild-card spot in the American League. Murakami, a two-time MVP in Nippon Professional Baseball, has transitioned to the American League with immediate impact. As Bleacher Report notes, the slugger—often dubbed the “Japanese Babe Ruth”—has already produced 20 home runs in his first 55 career MLB games, a feat surpassed only by Cody Bellinger and Wally Berger.
The power numbers are not merely high; they are statistically significant. According to reporting by Star News Korea, which cited baseball writer Francis Romero, Murakami is one of only three rookies since the 1901 season to hit 19 home runs before June, joining Mark McGwire (1987) and Pete Alonso (2019). His 19th home run, a two-run shot against the Minnesota Twins, featured an exit velocity of 108.4 mph.
Manager Grady Sizemore has noted the adjustment period for Murakami, specifically regarding the velocity differential in the American League compared to NPB. Murakami’s ability to stabilize his strikeout rate while maintaining an isolated power figure north of .300 has been central to the White Sox’s ability to remain above .500 through the final week of May. The team’s offensive output has increased by 14% compared to the same period in 2025, a shift directly correlated to Murakami batting in the cleanup spot.
Financial Value and Contractual Context
Murakami’s production has drawn attention not only for its historical rarity but for its cost-effectiveness. The White Sox signed the slugger to a two-year, $34 million deal during the most recent offseason. With a 2026 salary of $17 million, he is providing production that observers suggest is significantly undervalued compared to other high-profile signings.
For comparison, Kim Ha-seong, who signed a one-year, $20 million contract with the Atlanta Braves, currently earns approximately $3 million more than Murakami. This discrepancy in salary versus output has led to observations regarding the “cost-performance” of the deal. Murakami currently leads the American League in home runs, putting him ahead of Yordan Alvarez and Aaron Judge. Within the current collective bargaining agreement landscape, Murakami’s contract represents a significant win for the White Sox front office, as his production value—calculated via standard WAR metrics—is currently tracking toward a $45 million valuation for the 2026 campaign.
The Twins Series and Late-Game Dynamics
Despite the individual success of Murakami, the White Sox have faced challenges in recent contests against the Minnesota Twins. In a matchup on Tuesday, Murakami tied the game in the eighth inning with his 19th homer of the year, but the team ultimately fell 5-3 in 11 innings. The Chicago Sun-Times reported that the loss was particularly difficult for the slugger, who expressed frustration over a missed opportunity in a later at-bat.
“It’s obviously disappointing that we got a tough loss today. I just came up in the last at-bat, and I had my chances, I just couldn’t convert [Acuna from third]. I could have hit that fly out and, you know, scored a run.” — Munetaka Murakami, White Sox Slugger
The game also highlighted the contributions of other roster members, including Rikuu Nishida, who has shown defensive ability in right field, and pitcher Sean Burke, who delivered a resilient performance despite illness. Burke, who was dealing with a non-COVID-related respiratory ailment, was monitored by the medical staff throughout the game. Team trainers cleared him for his start after a final evaluation 90 minutes before first pitch, ensuring he could maintain his arm slot consistency.
“I honestly felt like my legs were under me, and I felt a lot better as the game went on. Tonight it felt like me and [catcher Drew] Romo were on a good page. We had a good game plan coming in.” — Sean Burke, White Sox Pitcher
Looking Toward the Summer Schedule
As the calendar turns toward June, the focus shifts to whether Murakami can maintain this historic pace. With 20 home runs already recorded, he remains on a track that would see him challenge significant single-season records. The White Sox, currently holding a .500 record of 27-27 following their recent series, appear to have found a core offensive piece capable of keeping them in contention within the AL Central. RotoWire confirmed the 20th home run came during a 15-2 victory over the Twins on Wednesday, providing a rebound for the team following their extra-inning defeat earlier in the week.
The White Sox now look toward a three-game weekend series against the Kansas City Royals, beginning Friday. The Royals currently sit 3.5 games behind the White Sox in the division standings, making this a pivotal series for the American League Central landscape. Murakami is expected to remain in the starting lineup for the opener, with the team’s medical staff reporting no lingering issues following his recent workload. As the White Sox approach the midway point of the first half, the club’s ability to secure a winning record in June will be determined by whether the secondary hitters—specifically those in the 5-through-9 slots—can capitalize on the high walk rate forced by opposing pitchers when facing Murakami.
