The Red Sox are set to start left-hander James Paxton (6-2, 3.46). He rebounded from his worst outing of the season to limit the New York Mets to three runs in six innings in an 8-6 victory last Saturday. Boston has won five straight games and that includes two wins over the Braves. The Red Sox hit .266 as a team vs right-handed pitching and we think they give Ryan Walker all he can handle here on Saturday. Let's roll with the Red Sox in San Francisco here.
