Barnes pitched 2.1 innings Tuesday in Baltimore after starter Eduardo Rodriguez exited early with a hamstring injury. He gave up two runs on one hit and one walk with two strikeouts, but came away with no decision when the rest of the Red Sox bullpen blew their 3-0 lead in the seventh inning.
Barnes left two inherited runners on first and second when he departed with one out in the seventh, and Fernando Abad turned those into the two runs on his ledger by allowing both to cross home plate on a Matt Wieters single. The 26-year-old would've likely been in line for his fourth win after picking up right where Rodriguez left off.
