Arroyo pitched 14 games this season before being placed on the disabled list with a shoulder injury at the latter end of June. It had been believed that his professional career would come to an end following the season, and that will indeed be the case. During his 16-year career, Arroyo threw for a 4.28 ERA and 1.30 WHIP over 419 games.

He is on the 60-day DL with a shoulder injury, so there likely won't be an official retirement until after the season, but he won't be pitching again. Arroyo was a fantasy-relevant pitcher from 2004 to 2013, even though he was always below average in terms of strikeouts. He's notched 148 wins and has a career 4.28 ERA, 1.30 WHIP and 1,571 strikeouts in 2,435.2 innings.

Arroyo landed on the disabled list last week with a right shoulder strain, and it now appears the injury will keep him sidelined until at least mid-August. The 40-year-old has struggled to a 7.35 ERA and 1.60 WHIP through 14 starts (71 innings) this season, leading him to contemplate retirement. With Arroyo not occupying a 40-man spot while on the 60-day DL, the Reds will give him ample time to recover before he ultimately makes a decision about his future with the team. Brandon Finnegan (shoulder) was activated from the 60-day DL in a corresponding roster move.

This move comes on the heels of Arroyo's loss to the Dodgers on Sunday, after which he admitted that his bothersome shoulder had him contemplating retirement. The 40-year-old has struggled so far this season, compiling a 7.35 ERA and 1.60 WHIP through 71 innings. He'll head to the disabled list to allow his shoulder to fully recover before ultimately making a decision about his future with the Reds. Ariel Hernandez was recalled from Double-A Pensacola in a corresponding move to fortify the bullpen, but it's not immediately clear who will replace Arroyo in the rotation for his next scheduled turn Friday against the Nationals.
