Miguel Castro - MLB News, Rumors, & Updates

Released by Arizona The Diamondbacks released Castro on Wednesday.

The veteran reliever missed significant time with a shoulder injury this season and when healthy posted a 5.93 ERA and 8:3 K:BB over 13.2 innings. However, Castro's solid track record should earn him another look somewhere, likely on a minor-league contract.

He walked Ozzie Albies before Austin Riley took him deep for a three-run home run to erase Arizona's lead. Although his 3.4 BB/9 is an improvement over previous seasons, it's still a high number and the right-hander walked a delicate line before Thursday's costly free pass. A one-time member of a closer-by-committee, Castro has since returned to a middle-relief role, one in which he had recent success. Castro entered the game with a 1.50 ERA over his previous 12 innings.

After starting out the season firmly behind Andrew Chafin as the Diamondbacks' primary closer, Castro has received back-to-back save opportunities and converted each of them without allowing a single hit or run.

After he was lit up for three runs a week ago while pitching on a third consecutive day -- his 16th outing in 34 games -- manager Torey Lovullo tweaked bullpen rotations to keep arms fresh. Castro and Andrew Chafin remain in high-leverage roles, including important ninth-inning situations.

MAY 15, 2023 • ROTOWIRE

Closes out win Castro allowed one hit and struck out one over a scoreless two-thirds of an inning to record the save in Friday's 7-5 win over the Giants.

Impact Castro got the call from the bullpen after Andrew Chafin got the first out of the ninth inning. It was Castro's second save of the season. Chafin has been the primary closer, but manager Torey Lovullo had him enter the eighth inning against a string of lefty batters. The sequence hinted at changes Lovullo mused about with Theo Mackie of the Arizona Republic. In reaction to a string of adverse relief work, the manager talked about shifting roles and avoiding overusing his most trusted arms, like Chafin.

MAY 13, 2023 • ROTOWIRE

Records first save Castro recorded his first save of the season, allowing one walk in a scoreless ninth inning against the Cardinals.

Impact Castro entered the game to protect an 8-7 lead after Andrew Chafin gave up three runs at the beginning of the ninth inning.

With a 2.25 ERA and 1.00 WHIP over eight innings, Castro is expected to continue handling high-leverage opportunities late in games.
