If there is one player the Chicago Cubs cannot afford to lose this year – for a variety of reasons, some performance-related, and some attendance-related – it’s probably shortstop Starlin Castro. Not only is Castro a unique talent and tearing the cover off the ball this Spring, the Cubs don’t have much in the way of a back-up capable of replicating Castro’s numbers.

So when Castro left yesterday’s split squad game against the Dodgers a little early, you’ll forgive me for holding my breath. Castro banged his knee at second base in the 5th inning, and then left the game thereafter.

Good news: the removal was merely precautionary, and Castro is OK. Exhale.
