Castro cleared waivers Thursday and was outrighted to Triple-A Buffalo, Evan Woodbery of MLive.com reports. Castro was claimed off waivers by Toronto in December but won't wind up making it to spring training as part of the team's big-league roster. The 25-year-old righty has just one big-league appearance to his name, allowing two runs in one inning for the Tigers last season.
Castro was designated for assignment by the Blue Jays on Thursday. Castro was claimed off waivers by Toronto in early December, but he'll be cast off the 40-man roster to make room for right-hander Tyler Chatwood. He could still compete for a bullpen role during spring training, but he'll likely begin the 2021 season in the minors.
Castro was claimed off waivers by the Blue Jays on Monday. Castro made his MLB debut last season with the Tigers, but he logged just one inning in one appearance. He should compete for a spot in Toronto's bullpen during spring training but will likely open the year at Triple-A.
Castro was optioned to Detroit's alternate training site following Monday's game against the White Sox. Castro was recalled Saturday, but he won't enter a ballgame before heading back to the team's alternate training site. He's appeared in just one contest this season, allowing two runs on a hit and a walk while striking out one over one inning.
The Tigers optioned Castro to their alternate training site Tuesday. Though Detroit is off until the weekend after its four-game series with St. Louis was postponed, the Tigers will still have to reduce their active roster from 30 to 28 men prior to Friday's series opener in Pittsburgh. As a low-leverage reliever with minor-league options remaining, Castro was a logical choice to lose his spot on the active roster. The 25-year-old right-hander made his MLB debut July 27 against the Royals, giving up two runs on one hit and one walk in a one-inning appearance.
