Castro signed with Colorado as a non-roster invitee Saturday, Daniel Alvarez-Montes of El Extrabase reports.

Any hitter who has the opportunity to earn playing time at Coors Field is worth a second look, and that's true for Castro even with the caveat that he's yet to earn a roster spot, let alone regular at-bats. He doesn't hit for much power, homering 15 times in 351 career games, but his .284/.309/.377 lifetime slash line is fine for a utility infielder. A starting role in Colorado may not be on the table, but a good spring could earn him a bench spot, putting him one injury away from consistent playing time.
