Donnie Murphy, 3B, Cubs (24.4 Percent Owned)
The 30-year-old journeyman is here only because he's been out-of-nowhere hot this month (8 HR, 15 RBI), but we're not exactly buying into a guy with a .213/.280/.406 career line.
L.J. Hoes, OF, Astros (7.3 Percent Owned)
This 23-year-old rook has been hot since coming over in the Bud Norris deal, hitting .329 with a homer and seven swipes in his first 22 big league games.
Trevor Rosenthal, RHP, Cardinals (18.5 Percent Owned)
Should something go wrong with Edward Mujica, who's dealing with arm fatigue and some soreness on his side, it might be worth a preemptive strike to add Rosenthal (pictured), who's whiffed 86 in 61.1 frames and would make a dynamite closer for a few weeks.
Tommy Hunter, RHP, Orioles (8.7 Percent Owned)
Jim Johnson's struggled most of the season, but he's still hanging onto the ninth inning, perhaps only by the skin of one more blown save. If that happens, Hunter and Francisco Rodriguez are worthy backups.
Charlie Morton, RHP, Pirates (6.2 Percent Owned)
Morton, 29, isn't an elite option by any stretch, but he's very steady and has hit a nice stride over his past four turns, over which he's allowed just seven runs in 27.2 innings with a 17:6 K:BB.
Joe Kelly, RHP, Cardinals (17.4 Percent Owned)
After spending the first part of 2013 in a relief role, Kelly has transitioned to the rotation rather well. He hasn't been able (or allowed) to go very deep into games, but he's still 5-0 with a 2.33 ERA in eight starts since July began.
