I find value at this high of a price in fading Trevor Williams, a bottom-of-the-rotation type starter.

Detroit is 6-3 in its last nine games. Pittsburgh is 5-9 in its past 14 games. The Pirates have lost in seven of Williams' last nine starts.

I've always liked Zimmermann, who can be extremely effective when healthy. Zimmermann is healthy again and pitching well with three quality starts in his last four outings. He held the Yankees scoreless in seven innings during his past start last Wednesday. Zimmeran gave up six hits, no walks and struck out six.

"Other than the one start ... I've been pretty good," Zimmermann was quoted as saying about his past appearances. "I feel strong, and the ball is coming out of my hand much better than it did in the first half of the season."
