LAKELAND, Fla. -- Left-handed pitcher Casey Crosby was optioned to Triple-A Toledo on Friday, despite catching Jim Leyland's eye Thursday when Crosby struck out Landon Powell of the Mets with a 93-mph fastball.
"Hopefully, we won't need him, but we want to get him stretched out in case we do," Leyland said. "He got his feet wet last year. He's got an idea what it's like up here.
"Normally he backs off to 89 or so when he feels like maybe he's not going to throw it over the plate, but he ended up throwing that 93 over the plate and got a strikeout out of it," Leyland added, referring to the 24-year-old pitcher's effort Thursday. "That was good to see. He'll get to the point where he's able to pitch with that velocity more often. He's young yet."
Crosby had a 1.29 ERA in four appearances this spring.
The Tigers also assigned lefty Kenny Faulk to Minor League camp.
"He's got the equipment to be a Major League pitcher," Leyland said of Faulk. "It's up to him."
