Batting average means how many hits they give up but it does not include walks, which when added back in, shows a far less effective group. And, the rate that inherited runners score on these guys shows that they are simply not capable of shutting down a rally late in the game. Who cares if the slugging is low if Timlin or Bradford comes into a game with men on and walks the first guy then gives up a single to allow a man to score? In two games against Texas all three got hit, Bradford and Timlin allowed men to score and Timlin needed good defensive plays from Manny and Millar to escape further damage.
