Frank Francisco, Mets: Jon Rauch continues to lurk, but despite Francisco's struggles since returning from the disabled list, he's still picking up save chances. He collected a handshake this past weekend against the Nationals, giving him 20 on the year, and should see more opportunities as the season comes to a close.
Grant Balfour, Athletics: Balfour has stabilized the A's bullpen since regaining the ninth inning, going 4-for-4 in save chances this month. His season ratios are pretty solid (2.56 ERA, 0.96 WHIP), so there is a good chance he finishes the year as the club's closer provided he continues pitching effectively.
Tyler Clippard, Nationals: Even with the return of Drew Storen, Clippard has held on to the ninth inning gig and continues to thrive in the role. With 12 saves in the past month, and a ledger of 27-for-31 on the season, it doesn't appear he's giving up the job anytime soon.
Addison Reed, White Sox: Reed continues to impress in his rookie campaign, collecting six saves during the past month, running his total to 21 on the season. At 70 ownership in Yahoo formats, there's a chance he's still available on your league waiver wire, which may be the only chance you'll have to own him with most trade deadlines already past.
Heath Bell, Marlins: We all know he's been nothing short of a complete disaster in his first season with the Marlins, but he is still making a fat salary and the club is going to want to get something in return for their investment. While Steve Chishek has been handling the ninth in recent weeks, there is a very good chance Bell will see save opportunities in September in an attempt to rebuild his confidence -- or build trade value -- heading into next year.
