CHICAGO — Patrick Bailey hit a tiebreaking single in San Francisco's nine-run 11th inning, and the Giants beat the Chicago Cubs 14-5 on Tuesday night.
Bailey drove in Christian Koss with a liner to center against Ryan Pressly (2-2). Jung Hoo Lee had a run-scoring single and Matt Chapman singled home two more runs in San Francisco's highest-scoring inning of the season.
Lee also hit a two-run homer as San Francisco bounced back from an ugly 9-2 loss to Chicago on Monday night. Chapman, who committed two of the Giants' four errors in the series opener, had three hits and scored twice.
The Cubs trailed 5-3 before rallying in the ninth, handing Justin Verlander another no-decision after he was in position for his first win with the Giants.
Justin Turner bounced a pinch-hit RBI single into right field against Ryan Walker. After Ian Happ struck out swinging for the second out, Kyle Tucker greeted Erik Miller (2-0) with a hard grounder back up the middle, bringing home the tying run.
Verlander pitched five innings of three-run ball. The three-time AL Cy Young Award winner signed a $15 million, one-year contract with the Giants in January.
The 42-year-old Verlander is winless in eight consecutive starts for the first time in his 20 major league seasons.
Miguel Amaya hit a two-run homer for NL Central-leading Chicago, which had won four of five. Dansby Swanson had two hits and scored twice while extending his hitting streak to eight games.
