Jonathan Broxton, RP (LAD): This is an easy one. Jonathan Broxton was, at one point, supposed to be the Los Angeles Dodgers closer of the future. The plans didn't get derailed -- Broxton's career isn't in the dumps or anything like that -- but they did get sidetracked when the Dodgers signed Takashi Saito in 2006. Saito has saved 80 games since then and overall, has been very solid. Recently he had an awkward feeling in his throwing arm after an outing and yada, yada, yada, he'll be out for six weeks. Broxton takes over the role and is an immediate must-own player. One thing people don't really talk about with Saito too much is the fact that he is 38. He's not a spring chicken, so you never know how injuries like this will impact him long term. Broxton is closer material. He has 46 strikeouts in 39.2 innings pitched with an ERA of 3.40. He'll need to get comfortable with his new role.
