Matt Dominguez, 3B, Astros (8.9 Percent Owned)
He's been the same low-average, solid-power guy for most of 2013, but Dominguez (pictured) has been hot in both departments over his past 15 games, with a .308 average, three homers and eight RBI.
Ryan Raburn, 2B/OF, Indians (15.5 Percent Owned)
Once a fantasy sleeper for his mid-teens power and sneaky 2B-eligibility, Raburn is doing it again after a horrendous 2012.
Erik Bedard, LHP, Astros (2.8 Percent Owned)
Of the 34-year-old's past 15 starts, only one has been really bad, and his ERA (3.52), WHIP (1.34) and K/9 (8.0) over that time have all been useful.
Brett Wallace, 1B, Astros (1.6 Percent Owned)
Yet another Astro, this former top prospect has hit for solid power since getting recalled in late June: Wallace has eight homers and 22 RBI in 32 games.
Andre Rienzo, RHP, White Sox (1.4 Percent Owned)
The first Brazilian-born pitcher to make it to the bigs, Rienzo takes Jake Peavy's spot in Chicago's rotation after a solid season at Triple-A (4.06 ERA, 1.34 WHIP, 9.0 K/9). The 25-year-old has allowed only nine hits and two earned runs over 13 frames in his first two outings.
