Barnes (5-2) allowed three hits and struck out five over two scoreless innings in Monday's 6-5 extra-inning win over the Phillies.
It initially didn't look like Barnes would pick up a career-high fifth win when the Phils had runners on second and third with one out in the 10th inning, but the right-hander avoided damage by striking out the final two batters. He later worked around a leadoff single in the 11th. There's some thought that Carson Smith (elbow) could see high-leverage work once he's back from Tommy John surgery, but until that time, Barnes will be manager John Farrell's go-to guy in tense situations.
