SEATTLE -- Darren O'Day is proving to be a good reliever for the Rangers if he can stay healthy. After a scoreless inning on Saturday, he went into Sunday's game as one of four relievers in the American League who had not given up an earned run in at least eight innings. The others were Mariano Rivera, Andrew Bailey and Sergio Santos. Since the start of the 2009 season, O'Day's 1.62 ERA is the third lowest among Major League relievers with at least 50 innings pitched. O'Day also went into Sunday's game averaging 12.9 pitches per inning this season. That's the lowest for any American League reliever.
