At Wrigley Field, the scoreboard didn’t just move—it kept piling up. The San Francisco Giants struck early, kept swinging hard through the middle innings, and left the Chicago Cubs reeling with an 18-3 win on Friday that felt like one of the most explosive offensive performances of the 2026 season.
The headline belonged to Matt Chapman. He finished with a career-high eight RBIs, going 2-for-3 with two home runs and a sacrifice fly. Those numbers didn’t just decide the game—they placed him among the most productive single-game run producers in Giants franchise history. Since RBIs became an official statistic in 1920, only Phil Weintraub (11 RBIs on April 30, 1944) and Irish Meusel (nine RBIs on Sept. 2, 1925) have recorded more RBIs in a game for the Giants. Chapman’s eight RBIs are tied for third-most in franchise history during that period.
He also matched the San Francisco-era franchise record for RBIs in a game. The list of Giants to pull it off includes Willie Mays, Orlando Cepeda, Brandon Crawford, Joc Pederson and Wilmer Flores, and Mays was the first to accomplish the feat after the franchise moved to San Francisco in 1958.
Chapman’s biggest hit came in the fourth inning. During a six-run rally, he launched his fourth career grand slam off Cubs starter Edward Cabrera. He added a sacrifice fly in the fifth, then unloaded again in the sixth with a three-run homer that traveled 432 feet and capped a seven-run frame.
The timing of it all mattered. In the process of tallying those RBIs, Chapman doubled his season home run total from two to four and increased his RBI count to 31.
San Francisco’s offense wasn’t limited to one superstar moment. The Giants racked up a season-high seven home runs and 19 hits. Willy Adames and Casey Schmitt each joined Chapman with two-homer games. and it was only the third time in franchise history that three Giants players hit multiple home runs in the same game. The previous occurrences came on July 2, 2002, and July 8, 1956.
Adames opened the scoring with a 427-foot two-run homer in the first inning. then added another long ball in the sixth for his 12th career multi-homer game. Schmitt homered in the fourth and again in the ninth. giving him a team-leading 15 home runs through the team’s first 64 games—the most by a Giant at that point in a season since Barry Bonds hit 18 in 2004.
Rookie Jonah Cox also made sure the night had depth. He collected three hits and hit the first home run of his major league career in the ninth inning.
That kind of production carried momentum into the standings conversation, because it didn’t arrive in isolation. The offensive outburst continued a recent surge for San Francisco: the Giants have scored 30 runs across their last two games while recording 39 hits. including a 20-hit performance against the Milwaukee Brewers on Thursday. They also won three straight games, matching their longest winning streak of the season.
Chapman’s grand slam carried additional weight inside the Giants’ bigger picture. It was San Francisco’s second grand slam in as many days and the team’s sixth of the season. with all six coming within the last 18 games. The Giants also became just the sixth team in league history to hit six grand slams in a stretch of 20 days or fewer.
When you look back over the numbers from Friday—Chapman’s career-high eight RBIs. seven Giants homers. and an 18-3 final—it’s easy to see why this didn’t feel like a typical win. It was a night built for a franchise marker. a historic run-producer. and an offense that kept finding new ways to put the pressure right back on Chicago.
