Hicks, Benson & Arcia are all top OF prospects. Benson has been struggling and was demoted from AAA earlier this year; Hicks has been holding his own but not excelling. Arcia was just promoted from high-A so he may struggle a little adjusting to higher quality ball, but he should come around in time.
Top pitcher I would look for would be Hermsen - blew away the competition in Fort Myers, was promoted to New Britain, and has exceeded expectations at AA. Darnell is also a good prospect, but he has only been average this year.
New Britain in general is really slumping right now - they've lost 12 of their last 16 games. They were in first place for a while, but have now slipped to 3rd, 5 games back.
