Teheran was up, 1-0, when he was left in to bunt so he could return for the ninth. Wood was locked in a 0-0 game. (Plus, Teheran's better with the bat.)
I'm not dissenting with Fredi's choice to leave Wood on the mound, per se; I'm disagreeing with his not pinch-hitting for Wood with a chance to score the go-ahead run.
