Diamondbacks Outright Joe Mantiply

By Connor Byrne | October 1, 2020 at 6:17pm CDT

OCT. 1: The D-backs announced that they have outrighted Mantiply to Triple-A Reno.

SEPT. 28: The Diamondbacks announced that they have designated left-hander Joe Mantiply for assignment. They reinstated infielder Domingo Leyba from the restricted list in a corresponding move.

Mantiply, a former Tiger and Yankee whom the Diamondbacks signed to a minor league contract last winter, threw 2 1/3 innings of four-run ball for the D-backs in 2020. The 29-year-old has tossed just eight major league innings and surrendered 12 earned runs on 13 hits with more walks (eight) than strikeouts (six) thus far.

Leyba, meanwhile, is back with the Snakes after receiving an 80-game suspension for a positive performance-enhancing drug test last March. The 25-year-old Leyba made his D-backs debut a season ago with 30 plate appearances and seven hits. FanGraphs ranked Leyba as the D-backs’ 26th-best prospect last November.

      Left-handed relievers never die, they just move around a heck of a lot.

        I feel like that trend will fade away if the 3 batter minimum stays. Relievers are going to be judged more on overall effectiveness regardless of handedness

          No it won’t. Left handedness is an advantage in baseball. Always has been always will be

    I haven’t seen an arm like that since Joe Montana. … I mean Joe Mantegna.

    Wait, Joe Mantiply.
