The Arizona Diamondbacks have three players capable to being an everyday shortstop -- Chris Owings, Didi Gregorius and Nick Ahmed -- which they could turn into pitching via trade.

Gregorius and Ahmed are believed to have the most trade value.

"If the Diamondbacks looked to deal Gregorius or Ahmed, they probably wouldn't get back a young, controllable, top-of-the-rotation pitcher. But, rival evaluators say, they could definitely get a useful part for a rotation rebuild," writes Nick Piecoro.
