I'm backing the Orioles on Sunday. Nathan Karns got a bad break when this series was moved to Tampa Bay because he has a terrible record at Tropicana Field. Karns is 1-1 with a 4.76 ERA overall this season but at home he has allowed 13 earned runs, 14 hits and five home runs. Last year he gave up six runs in five innings at the Trop. Karns is 0-1 with a 8.10 ERA in two career starts against Baltimore. The Orioles have an .805 OPS against right-handers this year. I'm backing the Orioles on Sunday.
