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. Fantasy managers should keep an eye on the Diamondbacks' use of Chafin and Castro moving forward, in case one of the two begin to pull away with the closing job.

Impact Castro worked the ninth inning in his last two appearances, picking up a save and a win. 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.
