Pirates' Ke'Bryan Hayes: To IL with back issue

Hayes was placed on the 10-day injured list Saturday with a back issue, Kevin Gorman of TribLive.com reports.

Hayes hasn't played since Tuesday amid a 3-for-30 slump, and perhaps the back issue is part of the reason he's only hit one home run in 35 games. Alika Williams is getting the call from Triple-A in a corresponding move.
