Jacoby Ellsbury -- 25 homersMazz: Under. Ellsbury opened some eyes last year - including those of opposing pitchers. He's a dynamic player. He's not a slugger.
Finn: Over. If pitchers finally figure out that a former weakness hitting the inside fastball is now a strength, the power numbers could slip. But that book should have been out last year, and Ellsbury hit nine homers last September.
