I don't think it would be too bad if he just spent some time with the team, and throws some side sessions for Larry so he can see how he has come since ST and perhaps help him with his secondary pitches. The guy, though paid handsomely, sacrificed a lot to be a Cub, giving him a little time with the big league club could be a thank you to him. I don't think this is a situation where they want to call him up and ask him to hold a tight game or start a game.
