CHICAGO (AP) — Matt Chapman joined some select San Francisco baseball company — including Willie Mays — with his massive day at the plate on Friday.The 33-year-old third baseman hit his fourth career grand slam, a three-run homer and added a sacrifice fly to finish with a career-high eight RBIs in the Giants’ 18-3 rout of the slumping Chicago Cubs. The eight RBIs tied the Giants’ San Francisco-era individual game record, shared by five others. The first to do it after the team relocated from New York in 1958 was Mays in on April 30, 1961.The other Giants to accomplish the feat were Orlando Cepeda (July 1961), Brandon Crawford (July 2019), Joc Pederson (May 2020) and Wilmer Flores (May 2025).“I feel like I’ve been doing a good job with runners in scoring position and I’ve been having a lot of opportunities with guys on base,” said Chapman, in his 10th major league season and third with the Giants.

Chapman hit his slam in San Francisco’s six-run fourth — and in a light rain — off Edward Cabrera. It barely reached Wrigley Field’s left-center basket.He added a sacrifice fly in the fifth.Chapman’s second homer capped the Giants’ seven-run sixth inning. He launched Ethan Roberts’ down-the-middle sweeper and sent it 432 feet to left before it struck an electric ad sign above the bleachers.
