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.

Key

Toronto Blue Jays

Closer: Kevin Gregg

Understudy: Jason Frasor

Lurkers: Scott Downs

The Jays have made Gregg available for trade to go along with their two in-demand setup men. Gregg has improved over his last eight outings, allowing only one hit and one walk since June 10, when you discount a June 23 gaffe.

Overlooked efficiency: Fuentes

It's doubtful any of these options would close if they leave Toronto, unless they were to head to Arizona. If Gregg exits, we might see a co-closer situation between Frasor and Downs. However, Frasor should be your first target if you're hoping Gregg is swapped, considering they've wanted Downs to remain in setup duty for the whole season.

This news probably means Gregg owners have missed their chance to sell him before the MLB trade deadline - not that he's hurting you much right now. If someone hasn't heard the news, maybe you should try to peddle him if you feel you're OK in saves.

Mound meetings

• The saves from the Baltimore Orioles' Alfredo Simon Friday and Sunday were scoreless; he worked around two hits Sunday. He has experience some bumps but has converted 13 of 15 save chances this year. Safe to say he'll hold off the rehabbing Mike Gonzalez (shoulder) for a while.
• Kerry Wood absorbed the loss for the Cleveland Indians on Sunday by yielding an RBI single in the bottom of the 10th. He recorded one out while giving up two hits and a walk. Wood hasn't had a save chance since June 29 and has worked just thrice this month.
  Even if Chris Perez takes over if Wood is traded, how many saves will Perez garner? If you're chasing the stat, you probably shouldn't think about that. Take the opportunities where you can find them.
• Brian Fuentes: stable? The Los Angeles Angels of Anaheim's savior has held opponents scoreless in 11 of his last 12 outings. In that time: 2.31 ERA, 1.11 WHIP, 12 K's and four walks in 11 2/3 frames. He's allowing a bunch of flyballs, but maybe his movement away from his slider and toward more changeups is helping.
• Texas Rangers stopper Neftali Feliz gave up a grand slam Friday to blow a four-run lead in the ninth. It wasn't a save sitch; he created his own mess on three hits and a walk. No worries, just a bump in the road for now.
