Pretty dreadful, actually. He's hitting .250 this year (2/8 with 5K's and 0 RBI). For his career, he's even worse, hitting just .161 (9/56 with 24K's and 13 RBI. Does have 3 HR's).
On BR, I'm using his "sub" stats, so assuming these are mostly pinch hitting appearances, though they may not all be.
I don't think there is any debate that Taylor benefits from regular playing time.
