Joe Mantiply has quietly become one of the most reliable left-handed relievers in baseball

If you said in March that the Diamondbacks’ best reliever after two months was going to be Joe Mantiply, I would have been unhappy with the direction of the team. Here we are after 51 games in which the team has played surprisingly competent baseball to the record of 25-26, in large part due to Mantiply’s contributions. The 31-year-old journeyman reliever seems to have found a long term home with the Arizona Diamondbacks thanks to a near full year of surprisingly strong pitching and has entrenched himself as one of the most trusted arms in the bullpen in 2022.
