Mantiply will be part of a ninth-inning committee going forward in Arizona, Steve Gilbert of MLB.com reports.
The 31-year-old southpaw has a 4.26 ERA, 1.18 WHIP, 12 strikeouts, zero wins and zero saves over his last 12.2 innings. However, Ian Kennedy seems like the more likely saves leader for the Diamondbacks after Mark Melancon was removed from the role.
