Certainly Ort and Valdez are just as speculative, too.
I'm no fan of counting recency ab ove all else, but before tonight, these are the last 4 weeks OPS Against...
.296 Schreiber
.569 Brasier
.569 Sawamura
.630 Houck
.647 Davis
.680 Strahm
.750 Danish
.768 Diekman
.785 Valdez
Now, I'm not saying Btrasier is better than those behind him, on this list, but going with the hot hand is not really something you can blame a manager for doing.
Last 2 weeks? Okay, Brasier is worse than maybe all but Diekman, but still...Diekman's 1.239 OPSA in the last 7 games clearly puts him behind Brasier as "the worst."
