Pittsburgh at San Francisco

Pittsburgh winds up a seven-game road trip here, coming off a 6-3 loss yesterday.

The Pirates are 3-10 as a road favorite, and 5-12 in A.J. Burnett's starts against a team with a losing record. Burnett hasn't been on his game with a 5.82 ERA his last three starts. Meanwhile, the Giants finish a nice seven-game home stand and have Ryan Vogelsong going, who has a 3.78 ERA his last three starts. The Giants are 18-5 in Vogelsong's last 23 starts with four days of rest, and the team is 16-6 in Vogelsong's last 22 home starts. Play the Giants.
