The Oakland Athletics are among the teams interested in trading for Pittsburgh Pirates closer Richard Rodriguez, sources told Jon Morosi of MLB Network.

The A's are prioritizing bullpen reinforcements heading into Friday's trade deadline, Morosi notes. Oakland relievers have posted a 3.78 ERA over 314 2/3 innings this season, and the unit ranks 20th in fWAR (1.3) among MLB bullpens.

Oakland signed Trevor Rosenthal in the offseason with the notion that he would serve as the club's ninth-inning option. But he recently underwent season-ending hip surgery before playing a game in 2021.
