Matt Chapman Powers Giants to Historic Rout with Grand Slam, 8 RBIs Against Cubs

Matt Chapman delivered a performance for the ages as the San Francisco Giants overwhelmed the Chicago Cubs 18-3 at Oracle Park, powered by Chapman's two home runs—including a grand slam—and a career-high eight RBIs that tied a franchise record for the San Francisco era.

The Giants’ offense erupted for seven home runs on the night, with Chapman’s bat leading the onslaught against a reeling Cubs squad. The third baseman’s fourth career grand slam came during a six-run fourth inning, helping the Giants seize control early. Chapman then punctuated his night with a three-run homer to cap the team’s seven-run sixth, putting the game well out of reach.

• Chapman’s eight RBIs tied the San Francisco-era record for a single game
• He hit his fourth career grand slam, and his second homer capped a seven-run sixth
• The Giants hit seven homers overall, their highest single-game total of the season
• San Francisco improved its standing in the National League with the lopsided win

San Francisco’s bats came alive in support of starting pitcher and quickly set the tone against the Cubs, who have been mired in a slump. Chapman’s first big blow—a grand slam—broke the game open in the fourth, as the Giants posted a six-run frame. By the end of the night, Chapman had amassed three hits and drove in more runs than in any previous game of his career.

The scoring continued in the sixth, as Chapman’s three-run homer closed out a seven-run inning for the Giants. San Francisco’s lineup combined for 18 runs, providing one of their most dominant offensive displays in recent memory. The team’s seven home runs showcased their power up and down the order and highlighted Chapman’s central role in the victory.

• Giants: 18 runs, 7 home runs, led by Chapman’s 2 HR and 8 RBIs
• Chapman: 3-for-5, 2 HR, 8 RBIs, setting a personal and club milestone
• Cubs: 3 runs, continuing recent struggles on the mound and at the plate

The Cubs’ pitching staff could not contain the Giants’ offense, yielding homers throughout the contest. Chicago’s woes were compounded by defensive lapses and a lineup that failed to keep pace. The loss further deepened the Cubs’ struggles, while the Giants capitalized on the opportunity to solidify their position in the playoff race.

Chapman’s memorable night joined the ranks of the top single-game RBI performances in franchise history since the club’s move to San Francisco. His blend of power and timely hitting provided the spark for a Giants team looking to build momentum as the season progresses. With their bats firing on all cylinders and Chapman leading the charge, San Francisco sent a resounding message to the National League.
