I think the Cubs could get Upton for Lilly. They were going to give up Upton for Cliff Lee, who is also a half year rental. Lee is better than Lilly, but the Rays were also rumored to be giving up more than just BJ. I think the Rays are definitely interested in trading from their ML roster. Between 2B, SS, CF, and RF they have been playing Brignac, Upton, Zobrist, Rodriguez, Joyce, Kapler, Bartlett, and Joyce. Other than Zobrist they have all been interchangable all putting up sub .730 OPS's. They'd love to trade 2 guys from that group and let the others play everyday in hopes that one or two get hot with consistent PT. Upton is the one that has had the most chance to play everyday and hasn't performed well enough, therefore he is probably most likely to be gone, IMO.
