Fantasy baseball closer depth charts: AL | NL

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 can cloud a team's bullpen picture.

Should you be concerned about a struggling stopper? Which relievers are climbing the depth chart? Are any injuries popping up? KFFL.com's Fantasy Baseball Closer Hot Seat keeps you informed when you're looking for saves.

Mound meetings

• Capps gun not firing blanks anymore

  Matt Capps' recovered velocity from last year has continued into this season. Helping the Washington Nationals closer fine-tune his mechanics and alleviate warm-up stress on his arm? "Towel drills" - throwing towels off the mound like he would a baseball, a common tactic that's a polarizing topic among pitching coaches.
  Despite some spotty control, Capps has converted all three save chances he has had this year. Relying more on his fastball - a stated goal heading into 2010 - should help him keep the job and keep Drew Storen down in the minors longer than farm freaks hoped.
• Leo Nunez (Florida Marlins) has delivered a nearly clean line in four games since blowing his first save chance of the year April 7. Nunez's line post-opener: five K's, one walk, one hit, two saves in four frames. His pitch counts in his last four games: 10, 21, 11 and 10, the final entry coming Tuesday in a non-save sitch. Paying off: Spring reports of him hiding his slider more effectively during his delivery.
