Diamondbacks release former top pitching prospect Jon Duplantier

The Diamondbacks have released right-hander Jon Duplantier, writes Nick Piecoro of the Arizona Republic. The move clears a spot on the D-backs' 40-man roster.

Arizona is hoping to bring Duplantier back on a minor league deal, according to Piecoro. The righty recently suffered a season-ending lat strain while pitching in the minors. Injured players cannot be placed on outright waivers, so the D-backs’ only options to clear a 40-man roster spot were to place Duplantier on the 60-day injured list (entitling him to big league pay and service time) or to release him. The organization has apparently chosen the latter course of action.

It’s not uncommon for players in this kind of situation to eventually re-sign on a minor league pact. Franklin Perez re-upped with the Tigers in May, for instance, a few days after being released when he underwent season-ending shoulder surgery. As a free agent, though, Duplantier would have the right to explore options with other organizations — assuming he clears release waivers.

Duplantier was once one of the better pitching prospects in baseball, appearing on Baseball America’s preseason top-100 lists in both 2018 and 2019. A series of injuries has derailed his progress to this point, and he’s tallied just 49 2/3 major league innings to date. Duplantier made four starts for the D-backs this year, allowing 19 runs across 13 frames.
