Nelson (back) was reinstated from the 15-day injured list Thursday.

EDGE Analysis

Nelson has been out for the past month due to back spasms, but he'll rejoin the Diamondbacks on Thursday after making one rehab appearance with Triple-A Reno. The 26-year-old has eight holds with a 1.57 ERA, 0.90 WHIP and 27:8 K:BB across 34.1 innings this year and should re-enter the high-leverage mix now that he's healthy.
