Fantasy Impact - Even if given the majority of at bats at shortstop, Ryan will still most likely not be fantasy relevant. A low batting average and lackluster power or speed leave him almost useless. The only reason he should have a roster spot is if the league values defensive play.
Predictions - .225, 50 R, 3 HR, 30 RBI, 25 BB, 80 K, 5 SB
