Based on upside Lee is the best bet for good numbers if he breaks out. It might not be this year but eventually he will have the best numbers.
Safest pick is P. Byrd. He looked decent when he came back last year, should be healthy and good to go this year. He wont hurt in any categories and should help in wins.
If your a real gambler go with Bedard. Matthew Pouliot wrote in his most recent column that if the O's go with a strict 5 man roatation ( which it is looking like they will ), then he wont pitch against the Yank's or Red Sox all four series the first month of the season. He could pay off well.
