Castro came to the Rockies as part of the Troy Tulowitzki trade in 2015, along with Jeff Hoffman and Jesus Tinoco. He notably made the jump from High-A to the Majors for the Blue Jays in order to bolster their bullpen that year.
His Rockies career was brief and, for the most part, unimpressive. An assortment of injuries, including one to his shoulder last season, derailed much of the flamethrower’s promise. Still only 22-years-old, his designation for assignment surprised many. However, Jerry Schemmel revealed at the Purple Row Breakfast this morning that Castro fell out of favor with the organization due to attitude issues, and was even described as “uncoachable.”
Hopefully Castro is able to regain the ability that made him such a sought after prospect when the Rockies acquired him. All the best in Baltimore, Miguel.
