In fantasy baseball, the closer position remains volatile. Rarely does every closer hang on to the job for an entire season - injuries, poor performance and managerial decisions cloud a team's bullpen picture.

Key

Los Angeles Dodgers

Closer: Jonathan Broxton

Understudy: Hong-Chih Kuo

Lurkers: Kenley Jansen

Brox primarily threw fastballs in his first spring action, retiring three of the four batters he faced Monday. It's early, but skipper Don Mattingly was merely glad Broxton didn't have much trouble.

The righty is considering throwing more split-finger fastballs this season but hasn't shown a heavy desire to do so. Given he was struggling so much with his top two pitches last season, it'd be interesting for him to experiment with a third. It's a possible avenue for him to rediscover his high 2009 grounder rate. It's just another layer of Broxton's recovery to watch.

He reportedly gave it a full go with decent results. The San Francisco Giants' stopper should appear in game action soon. Monitor this, but there's no indication he won't start the season on time.
• Heath Bell (calf) threw batting practice Wednesday and will pitch in a game in the next three or four days, per San Diego Padres manager Bud black. No reason to worry.
