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.

• Arizona not closing bullpen book yet

  The Arizona Diamondbacks are making progress with their bullpen under interim manager Kirk Gibson. Since he took over, they have a 4.24 ERA in 10 games. Gibson and pitching coach Mel Stottlemyre Jr. have had the relievers doing their own scouting and comparing notes before each series. Gibson has also trusted them more than previous manager A.J. Hinch.
  This doesn't really give us any more indication of who'll be closing games. Juan Gutierrez and Chad Qualls are both speculative options, if you're desperate. However, if the rest of the 'pen can improve, they might set up Arizona's closers for a few more save chances.
• The Cincinnati Reds have been kicking tires on right-handed relievers. Kerry Wood, anyone? Whoever they add shouldn't have much impact on Francisco Cordero's job security, though, unless they're high on Wood as at least an alternative to spell the incumbent.
