Diamondbacks' Keynan Middleton: Out with toe sprain

Middleton was placed on the 15-day injured list Sunday, retroactive to Sept. 17, with a sprained left big toe.

Middleton has surrendered seven runs across his past three outings and will now be unavailable for at least the next couple weeks. The 29-year-old is eligible to return in early October for the final few games of the season, though Arizona could instead opt to shut him down.
