SAN FRANCISCO — For most of Friday night, it seemed, Mike Yastrzemski was doing one of two things: driving runs in, or watching them leave the yard.
Three of Yastrzemski’s four trips to the plate resulted in Giants runs, including a second-inning solo shot, as San Francisco kicked off a seven-game home stand by getting back in the win column with a 5-3 triumph over the Pittsburgh Pirates.
Yastrzemski’s contributions were just enough to back up a six-inning, two-run effort from Carlos Rodon, who racked up seven more strikeouts without issuing a walk but allowed twice the number of home runs as he had all season at Oracle Park.
