The Red Sox are the No. 1 scoring team in baseball averaging 5.2 runs per game. That figure rises to 7 runs per game if you go by the last seven games. Boston draws lefty Zac Lowther, making his first big league start, probably followed by a bevy of Baltimore relievers as this shapes up as a bullpen game for the Orioles. The Red Sox are 7-3 versus lefty starters. 

Garrett Richards will be on the hill for Boston. He's pitched better his last two starts, but struggled early in the season when he had to go against the Orioles twice. This already is the Orioles' third look at Richards, whose career record against the Orioles is 0-5 with a 6.38 ERA in 10 appearances, including six starts. 

The Orioles have been getting runners on base. They've scored 5 or more runs in four of their last six games.
