Remember you will have to cut your roster to 27 after the Rookie Draft. These questionable players need to be thought about. I tend to keep one player in that catagory if he can play 3 or 4 positions and actually plays 40-50% of the time.
Last year that was Frank Menachino of Toronto. He was valuable as the season progressed and actually hit .280 for me. He could play 2B, 3B, & LF. I used him strictly against left handed pitchers. If the players in question are playing less or play a single position I would cut them and expand your back up bench through the FA Draft. Just my opinion. This year I am currently sitting on Billy Hall. So far anyway.
