Treinen pitched four shutout innings Sunday after Joe Ross was struck in the heel by a comebacker, allowing two hits and striking out three.
He's now sporting an 0.00 ERA and 8:1 K:BB ratio through eight spring innings. Treinen appears ticketed for long relief to begin the season, but if Ross' injury proves to be more serious than originally thought, it's possible Treinen could get a turn or two in the rotation in early April.
