SF Giants lose to Cubs on 10th-inning walk-off single by Busch
CHICAGO - There would be no encore to the seven-homer barrage.
Following a 12-run showing on Thursday and an 18-run flurry on Friday, the Giants’ three-game winning streak was snapped as they lost 3-2 to the Chicago Cubs on Saturday afternoon at Wrigley Field on a walk-off, 10th-inning single by Michael Busch.
This defeat marks the fourth time this season San Francisco has failed to extend a winning streak to four games.
“The biggest thing is they absolutely battled their (butts) off,” said manager Tony Vitello. “We come up a little bit short.”
The Giants positioned themselves to secure a series victory when Matt Chapman, who hit two homers and drove in eight runs on Friday, drove in Jung Hoo Lee with a ninth-inning sacrifice fly to give San Francisco a 2-1 lead.
Keaton Winn was one out away from his second five-out save of this road trip, but Chicago’s Pete Crow-Armstrong tied the game with a no-doubt solo shot, his second home run of the afternoon.
San Francisco (26-39) failed to score 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.
The Cubs’ Dansby Swanson, who scored the winning run, initially held up at third base, but right fielder Victor Bericoto let the ball scoot underneath his glove, allowing Swanson to waltz home and end the game.
Right-hander Landen Roupp rebounded after allowing a career-high eight runs on Monday to Milwaukee, surrendering just one run over 5 2/3 innings with three walks and five strikeouts Saturday. The lone run Roupp allowed was a solo homer to Crow-Armstrong.
“I think today was a step in the right direction for me,” said Roupp, who has a 4.00 ERA over 13 starts. “Obviously, gotta cut down on the walks. That first inning, two back-to-back walks isn’t going to cut it. But overall, I think I made a lot of good pitches. Really, one mistake all day, and it was the fastball to PCA.”
With a pair of singles, Lee extended his hitting streak to 14 games, the longest active streak in the majors. Lee is 27-for-52 (.519) during his hitting streak and currently ranks third in the majors in batting average (.324). Along with the hits, Lee collected his first steal of the season by swiping second in the seventh inning.
“When I was on the (injured list), I didn’t try to just take time off the field,” Lee said through team interpreter Justin Han. “I went into the cage and just stood there. I didn’t make any swings, but I was just trying to see a lot of pitches on the Trajekt (machine), which helped out a lot.”
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 at second base 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 Seiya Suzuki grounder, then threw him out.
“When you got a guy like Roupp, the better defense you play behind him, the more you’re subtly encouraging him to attack the zone, which he did today,” Vitello said. “With those guys on our staff being ground ball guys, you’ve got to be ready at all times. That group, collectively, has been phenomenal.”
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.
The Cubs threatened to take the lead in the sixth when former Giant Michael Conforto followed Crow-Armstrong by drawing a walk and stealing second, but San Francisco escaped with the tie intact. Roupp struck out his next two batters before being replaced by Caleb Kilian, who got Oakland’s Nico Hoerner to hit an inning-ending fly out 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.
Up next
Right-hander Trevor McDonald (2-3, 4.50 ERA) will take the mound on Sunday Night Baseball against the Cubs’ Jameson Taillon (2-5, 5.13 ERA). Should the Giants win, they won’t just take the series from Chicago, but they’d split their 10-game road trip.
