Brice Turang has had 142 plate appearances since July 26th. He has one extra base hit in that time period (a double).
He'll fall just short of qualifying as a full-time player (he needs 502 plate appearances and he'll get about 460). If he had reached 502, he'd be the third worst position full-time player on offense in baseball.
I guess there is no one any better and he plays great defense, but he should be a late-inning defensive replacement and a pinch runner, not your starting second baseman.
