Because of having the worst bullpen ERA in the majors and being a below average defensive team, especially without Mike Trout, the Angels need strong starting pitching. They haven't been getting that from Dylan Bundy. 

Bundy has a whopping 15.83 ERA in his last three starts. The Giants faced Bundy last August and he couldn't reach the fifth inning giving up two homers in an 8-2 loss. 

The Giants have been a major surprise with the second-best record in the National League and third-best overall mark. San Francisco is a strong 22-7 as home chalk.

The Giants hold bullpen, defense and starting pitching edges with Johnny Cueto on the mound to oppose the cold Bundy. Cueto isn't an ace anymore, but he's a dependable middle-of-the-rotation starter with a lifetime 1.35 ERA against the Angels in four starts, including a 7-2 win against them last August.
