Munetaka Murakami delivered his first career grand slam as the Chicago White Sox erupted for a 10-1 victory over the Oakland Athletics on April 17, 2026, at Sutter Health Park in West Sacramento, California. The powerful left-handed slugger launched a towering shot into the left-field seats in the fifth inning, clearing the bases and igniting a six-run inning that transformed a tight contest into a rout. The blast marked Murakami’s fifth home run of the young season and his first four-RBI effort in Major League Baseball, underscoring his continued adjustment to life in the American League after a storied career in Nippon Professional Baseball.
The grand slam came off Athletics starter D. Martin, who had retired the first two batters of the inning before walking leadoff hitter Luis Robert Jr. And surrendering a single to Andrew Vaughn. With the count at 2-1, Murakami deposited a 420-foot fastball into the bleachers, giving Chicago a 6-1 lead and eliciting a roaring response from the sparse but enthusiastic crowd. The inning continued with RBI singles from Eloy Jiménez and Gavin Sheets, extending the advantage to 10-1 by the time the side was retired. Oakland managed only a solo home run by Nick Kurtz in the seventh, avoiding a shutout but failing to threaten further.
Defensively, the White Sox received a stellar effort from starting pitcher Aaron Bummer, who worked six strong innings, allowing just one run on four hits while striking out seven and walking none. Bummer’s efficient outing — 89 pitches with 62 for strikes — set the tone after Martin’s early exit due to arm fatigue. Relievers Kendall Graveman and Alex Colomé combined for three scoreless frames, preserving the shutout bid until Kurtz’s late-inning homer. The victory improved Chicago’s record to 7-13 on the season, while Oakland fell to 10-10, continuing their struggle to find consistency in a tightly contested American League West race.
Murakami’s offensive explosion was a stark contrast to his early-season struggles, during which he posted a .195 batting average and struck out in over 30% of his plate appearances. However, his recent work with White Sox hitting coach Ryan Fuller has begun to yield results, as the slugger has shown improved pitch recognition and a greater willingness to work deep into counts. In the seven games leading up to the Athletics series, Murakami hit .316 with four home runs and nine RBIs, raising his season line to .241/.328/.512. His grand slam against Oakland represented the culmination of that adjustment, combining raw power with disciplined plate approach.
The grand slam also carried historical significance, as Murakami became the first Japanese-born player to hit a grand slam for the White Sox since Kazuhisa Ishii in 2002. More broadly, it marked only the 12th grand slam by a Japanese-born player in MLB history, joining the likes of Hideki Matsui, Shohei Ohtani, and Seichi Uchikawa. Murakami’s achievement was celebrated in the postgame clubhouse, where teammates praised his poise and power under pressure. “He’s been waiting for this moment,” said Vaughn. “You could see it in his eyes — he was locked in.”
Looking ahead, Murakami is scheduled to face the Athletics again in the second game of the series on April 18, 2026, with Dylan Cease set to start for Chicago. A strong performance could further solidify his role as a middle-of-the-order anchor for a White Sox offense seeking to climb out of the American League basement. As of April 17, Chicago ranked last in the AL in both batting average (.195) and on-base plus slugging (.602), but Murakami’s recent surge offers a glimmer of hope for a team attempting to rebuild around a blend of young talent and experienced veterans.
