Lorenzen retired all four batters he faced in Saturday's loss to the Nationals, striking out one. He currently has a 3.48 ERA, 1.42 WHIP and 27:10 K:BB over 31 innings.
This came on the heels of Lorenzen giving up four runs to the Pirates on Wednesday, and he had allowed at least a run in four of his previous five outings in total.
