If you have a runners in scoring position and facing a tough lefty, Buehrle is really not the guy for that spot, he pitches for contact. No one will like my opinion here, but honestly Delabar has reverse splits. Yes he has command issues but he gets whiffs and is pretty damn tough against lefties (career .184 against and >11 K/9). I don't know what use Tepera has for this roster unless it's a blowout but Delabar could replace a lefty in the pen.
