Scooter Gennett - Milwaukee Brewers (8% Owned) - 3 HR's in the past 7 days is definitely a mirage, but Gennett can be a useful plug-in option for the rest of the season with Rickie Weeks on the DL. There is definitely some pop in the bat, and he can run a bit but it's his patient plate approach and ability to bat to ball that leaves me excited about his prospects.
Corey Dickerson - Colorado Rockies (1% Owned) - Dickerson has been making the most of every opportunity and has hit at every stop of his career. There is double digit power in the bat (he hit 32 HR's two years ago in the Sally league) and it obviously plays up in Colorado. Charlie Blackmon appears to be getting the majority of the AB's in Car-Go's absence, but I expect Dickerson to steal most of those away in the coming weeks.
J.B. Shuck - Los Angeles Angels (4% Owned) - Shuck has been a lot of fun to watch atop of the Angels lineup. He can swipe a bag and is in a great position to accumulate a ton of runs. Shuck doesn't strike out often and tends to get hits in bunches.
Eduardo Nunez - New York Yankees (2% Owned) - Nunez has arguably the power power of all available SS options and has guaranteed playing time for the next few weeks. He's hitting towards the bottom of a weak New York offense, but if you need to make up ground in HR, Nunez could provide a late-season boost.
Khris Davis - Milwaukee Brewers (1% Owned) - Another pure power play, Davis has been mashing in his short 32-game sample (164 wRC+). If he can cut down on the strikeouts (and his minor league numbers suggest he might be able to) Davis can carve out a nice role in Milwaukee next year.
Jake Arrieta - Chicago Cubs (1% Owned) - Arrieta was dominant in his first start for the Cubs as he shut down the St. Louis Cardinals for 7 innings. He's a former top prospect, so this performance didn't come out of nowhere and I think he's capable of a few more of these starts. Arrieta will get plenty of opportunities in Chicago, and ultimately I think he sticks in 2014 and becomes a useful fantasy SP.
Brad Peacock - Houston Astros (1% Owned) - It's a foolish move to invest in Houston starting pitching, but I think Peacock bucks the trend. Since joining the rotation, Peacock has put up excellent numbers: 19.1 IP, 20 Ks, 8 BBs, 4 ER, and a W. He might be more than a spot-starter for the remainder of 2013.
J.J. Hoover - Cincinnati Reds (3% Owned) - Hoover has been unscored upon in his last 21 appearances, spanning 24.1 IP. This is largely due to his improved control as he only has allowed one walk in his past 10 appearances. Even if you aren't in a hold league, take advantage of Hoover's dominance and let him contribute quality innings.
Danny Duffy - Kansas City Royals (1% Owned) - I don't know what to make of Danny Duffy. He's seen very little success since his perch on top of many prospect lists, but he also pitched 6 innings of 1-hit ball against the Detroit Tigers. He isn't guaranteed a rotation spot, so I'd hold off for now, but another positive start could signal a real change for Duffy.
Paco Rodriguez - Los Angeles Dodgers (5% Owned) - Another RP with no chance of closing, Paco Rodriguez is going to contribute the quality innings that help bolster fantasy pitching stats in the playoffs. He gets a lot of high-leverage opportunities, which can help him poach a few W's, and he strikes out more than a batter per innings. Run Paco out there and let him eat some critical innings.
