The thumb injury Hanley Ramirez sustained in the World Baseball Classic championship game Tuesday night will cost the Dodgers shortstop anywhere from 2 to 10 weeks.

With Opening Day 12 days away, that makes Ramirez doubtful for the Dodgers’ season-opening series against the San Francisco Giants — if not longer.

Ramirez was scheduled to arrive in Phoenix later today to undergo an MRI exam. The Dodgers will learn the full extent of his injury then.

Luis Cruz was scheduled to start at shortstop in the Dodgers’ exhibition game against the Kansas City Royals on Wednesday and could be a longer-term option to replace Ramirez if the team chooses to move him from third base.
