Should Cubs Trade Starlin Castro?

Starlin Castro says he feels awful about his mental lapse during Monday’s loss at San Francisco when he lost awareness of how many outs the Cubs had in the fifth inning.

‘‘I want to say I’m sorry to my teammates and it will never happen again,’’ he said. ‘‘I’m real embarrassed. There’s no excuse for that. That can’t happen in a game. That will never happen again.’’

Here’s the troubling part. The above quote from Castro wasn’t from Monday’s post-game.
