'Whoa Fella", Piniella has already pretty much said that he will only bring up players he think that can help. I would expect him to maybe bring up 6/7 players and to answer your other question, Yes players have to be on the 40 man to be brought-up. I would expect to see both Gallagher and Hart brought up at some point but the Cubs made a great decision in sending them to AA to keep starting. I would expect that as season progresses you may see some starters get a well needed day off.
