Matt Chapman powered San Francisco to an 18-3 demolition of the Chicago Cubs on Friday, delivering a fourth career grand slam, a three‑run homer and a sacrifice fly. He finished with a career‑high eight RBIs, tying the Giants’ San Francisco‑era single‑game record. His performance sparked a rally that turned a close game into a blowout.

Chapman’s slam marked the Giants’ second consecutive grand slam and the sixth of the season, all coming in the last 18 home games. Only five teammates have matched the eight‑RBI feat since the club moved from New York in 1958, beginning with Willie Mays in 1961. Orlando Cepeda, Brandon Crawford, Joc Pederson and Wilmer Flores join that exclusive list. The power surge fuels San Francisco’s offense.

The Giants posted their third straight win, amassing 19 hits while the Cubs floundered in a slump that has them near the bottom of the NL West. San Francisco sits at 26-38, still chasing a .500 mark. Chapman, now at four homers and 31 RBIs on the season, said the recent surge in solid contact is finally clicking. Kapler praised the depth.
