CHICAGO — There would be no encore to the seven-homer barrage.

After scoring 12 runs on Thursday and 18 more runs on Friday, the San Francisco Giants lost 3-2 to the Chicago Cubs on Saturday afternoon at Wrigley Field on a walk-off, 10th-inning single by Michael Busch.

Matt Chapman, fresh off tying the San Francisco-era record with eight RBIs on Friday, drove in the go-ahead run in the top of the ninth inning with a sacrifice fly. Keaton Winn was one out away from recording his second five-out save of the road trip, but Chicago’s Pete Crow-Armstrong tied the game with a no-doubt solo shot, his second home run of the afternoon.

The Giants failed to score a run in the top of the 10th despite bringing Rafael Devers and Luis Arraez to the plate with a runner in scoring position, setting the table for Busch’s walk-off single.

Right-hander Landen Roupp rebounded after allowing a career-high eight runs on Monday to the Milwaukee Brewers, surrendering just one run over 5 2/3 innings.

Devers hit his eighth home run of the season, a solo shot in the top of the eighth inning.

Roupp was the beneficiary of several excellent plays by his defense. In the second, Arraez picked a tough short hop out of the dirt before firing to first for the out. In the third, Roupp initiated a difficult 1-6-3 double play. In the fourth, shortstop Willy Adames ranged up the middle to vacuum up a grounder off the bat of Seiya Suzuki, then threw to first for the out.

San Francisco and Chicago traded zeros until the sixth inning, when both teams traded solo homers. Devers got the Giants on the board with a solo blast off the Cubs’ Caleb Thielbar, but Crow-Armstrong notched things back up at one apiece with a towering solo shot of his own.

The Cubs threatened to also take the lead in the sixth when former Giant Michael Conforto followed Crow-Armstrong by drawing a walk and stealing second base, but San Francisco escaped the frame with the tie intact. Roupp struck out his next two batters before being replaced by Caleb Kilian, who got Nico Hoerner to hit an inning-ending flyout after allowing a walk and a single to load the bases.

Left-handed reliever Erik Miller teetered on the edge of disaster with two outs in the seventh by loading the bases on two singles and a hit-by-pitch, but he escaped trouble by striking out Alex Bregman swinging to end the frame.
