SAN FRANCISCO — Mike Yastrzemski homered and drove in four runs, Blake Snell struck out eight in five innings, and the San Francisco Giants beat the Milwaukee Brewers 13-2 on Wednesday night.
Jerar Encarnacion also homered and had three RBIs, and Tyler Fitzgerald and Patrick Bailey each had three hits.
''Just good at-bats across the board,'' manager Bob Melvin said. ''We put some pressure (on the Brewers), had some big hits. (Going) 7 for 15 with runners in scoring position makes a big difference.''
The Giants knocked around Brewers starter Colin Rea (12-5) early, beginning the game with consecutive four-run innings. In the first, a passed ball on Brewers catcher Williams Contreras accounted for the first run. LaMonte Wade Jr. followed with an RBI single, and then Encarnacion hit a a rare opposite-field homer to right to give the Giants a 4-0 lead.
Encarnacion's homer was the 75th opposite field homer by a right-handed hitter in Oracle Park history and first by a Giant this season.
''I thought it had a chance to go because that's where most of my power is,'' Encarnacion said through interpreter Erwin Higueros. ''When I saw it leave, I knew it had a chance to go.''
The first four Giants batters had hits in the second inning for four more runs. Fitzgerald had an RBI double, and Yastrzemski followed with a three-run homer. Yastrzemski drove in his fourth run in the fourth inning with an extra-base hit. Matt Chapman homered later in the inning to pad the advantage to 10-1.
Melvin said that Yastrzemski is playing his best baseball of the year.
