Leonys Martin OF, Rangers
MIXED LEAGUES
(Yahoo: 17 percent owned)
Martin is beginning to show why he was hyped as a potential sleeper this spring. The 25-year-old currently owns an 11-game hitting streak, including a two-homer performance against the Yankees' Hiroki Kuroda on Tuesday night. He's now batting .288/.339/.452 with 15 extra-base hits (five homers), 13 stolen bases and 29 runs scored in 67 games, delivering on the potential he displayed in the minors last season. Martin still needs to prove that he can hit left-handed pitching, so I'd be careful about trusting him as an everyday option right away, but he has the ability to help in all five categories if utilized correctly. With Craig Gentry on the disabled list with a non-displaced hand fracture, he should be in the lineup on most days.

Ben Revere OF, Phillies
MIXED LEAGUES
(Yahoo: 43 percent owned)
Revere got off to a slow start with the Phillies, but he has turned things around quite nicely since the beginning of May, hitting .317 with 12 stolen bases over his last 44 games. This includes a current 10-game hitting streak during which Phillies manager Charlie Manuel has entrusted the 25-year-old center fielder as his leadoff man once again. Sure, the slap-hitting Revere isn't going to provide any power, but he stole 40 bases in 124 games last season and 34 in 117 games in 2011. That speed can be a major difference-maker in all formats.

Junichi Tazawa RP, Red Sox
MIXED LEAGUES
(Yahoo: 15 percent owned)
Andrew Bailey has looked pretty shaky of late, allowing five runs on seven hits (including three home runs) and four walks in four innings over his last four appearances. The Red Sox are saying that he's healthy, but he has shown diminished velocity in recent outings and missed some time earlier this season with biceps soreness. Given his long injury history, the smart play may be to think ahead. Tazawa is the likely alternative if a change is eventually needed at closer, as he got the nod over Koji Uehara when Bailey and Joel Hanrahan were both on the disabled list. The 27-year-old right-hander owns a ridiculous 1.89 ERA and 83/8 K/BB ratio in 76 1/3 innings dating back to the start of last season, so he could prove to be an elite option if he gets an extended opportunity.

Brandon Moss 1B/OF, Athletics
MIXED LEAGUES
(Yahoo: 32 percent owned)
The free-swinging Moss was never a good bet to duplicate his .291 batting average from last season, as he was helped by a .359 BABIP (batting average on balls in play), but fortunately his pop has remained intact. While the 29-year-old is striking out at a ridiculous rate of 30.9 percent, he has connected for 13 home runs through 67 games this season, including four in his last seven. Only eight first base-eligible players have more home runs. Don't look for that batting average to bounce back, as he's right about where he should be, but his thump comes in handy if you need to fill a CI (corner infielder) spot.

Dillon Gee SP, Mets
MIXED LEAGUES
(Yahoo: 14 percent owned)
Even though Gee gave up a walkoff two-run homer to Freddie Freeman in the bottom of the ninth inning on Monday night, it doesn't change the fact that he has turned his season around. After putting his rotation spot in jeopardy with a 6.34 ERA across his first 10 starts, the 27-year-old right-hander has a ridiculous 1.53 ERA and 32/4 K/BB ratio in 29 1/3 innings over his last four outings. While he has been battling elbow tendinitis for most of the season, his velocity has been on the rise since the early part of the season. This could be a sign that he has regained strength following surgery last July to fix an artery in his pitching shoulder. Gee was quietly pitching very well before that surgery, so perhaps he's picking up from where he left off.

Mitch Moreland 1B, Rangers
MIXED LEAGUES
(Yahoo: 38 percent owned)
Moreland landed on the disabled list earlier this month with a right hamstring strain, but he went 6-for-12 with a home run and three doubles during his rehab assignment with Double-A Frisco and will be activated for Friday's series opener against the Cardinals. He'll be a welcome sight for the Rangers, who have struggled to score runs for most of the month. The 27-year-old first baseman was enjoying his best season prior to the injury, batting .288 with 12 home runs, 29 RBI, and an .899 OPS through 58 games, so he should be picked up in leagues where he was dropped.
Nick Franklin 2B/SS, Mariners
MIXED LEAGUES
(Yahoo: 29 percent owned)
It hasn't taken long for Franklin to get comfortable at the major league level. The 22-year-old switch-hitter is batting .280/.365/.480 with three home runs, six RBI, three stolen bases, and a 10/12 K/BB ratio in 22 games since his promotion from Triple-A Tacoma late last month. He's even held his own against southpaws in a small sample, which has been a trouble spot for him in the past. His recent seven-game hitting streak saw him pushed to the No. 2 spot in the order, which gives him a nice boost in value. Franklin contributes in all categories, so he's a worthwhile addition in most formats. Pick him up if you're looking for a replacement for Everth Cabrera.
Ricky Nolasco SP, Marlins
MIXED LEAGUES
(Yahoo: 21 percent owned)
Nolasco has long been one of those pitchers whose results didn't match up with what advanced metrics like xFIP and SIERA were saying, but he's finally enjoying some success this season. Through 15 starts, the 30-year-old right-hander has a 3.61 ERA and 76/23 K/BB ratio over 94 2/3 innings. He currently has his lowest ERA since 2008 and his highest swinging strike rate since 2010. That's a pretty good way to boost your trade value. Nolasco is worth using in all formats this weekend against the banged-up Giants, who could be one of his potential suitors in the weeks to come.
Nate Schierholtz OF, Cubs
MIXED LEAGUES
(Yahoo: 15 percent owned)
After joining the Cubs on a modest one-year, $2.25 million contract over the winter, Schierholtz has thrived in a platoon role in right field, batting .293/.343/.553 with nine home runs, 26 RBI, four stolen bases, and 26 runs scored in 60 games. The 29-year-old quietly owns an .847 OPS against right-handed pitching since the start of 2011, which is higher than the likes of Jay Bruce and Evan Longoria. Yep, I was surprised by that myself. Schierholtz has only logged 22 plate appearances against left-handers this season, so the Cubs have been very strict about his role. He's best utilized in leagues where you can make daily lineup changes, but he's doing enough to warrant attention in deeper mixed formats.
Joaquin Benoit RP, Tigers
MIXED LEAGUES
(Yahoo: 30 percent owned)
We don't need a meat thermometer to tell us that Valverde is almost cooked. With his velocity sitting a career-low, "Papa Grande" has allowed 11 runs on 15 hits (including six home runs) in 7 1/3 innings over his last eight appearances. The veteran right-hander served up just three home runs in 71 appearances last season and five in 75 appearances in 2011. While Tigers manager Jim Leyland has resisted making an official change at closer, Benoit converted a save chance on Sunday against the Twins and looks like the best in-house hedge. I wouldn't be surprised if the Tigers are in the market for a closer (Jonathan Papelbon?) around the trade deadline.
Eric Young, Jr. OF, Mets
MIXED LEAGUES
(Yahoo: 2 percent owned)
After being designated for assignment by the Rockies last week, Young was acquired by the Mets on Tuesday in exchange for right-hander Collin McHugh. It's a pretty good spot for the 28-year-old speedster, as there's not much standing in the way of regular playing time. He batted leadoff and started in center field in his Mets' debut on Wednesday night, two real areas of need for the club. Young is a .261/.329/.342 career hitter, so don't expect much help in the batting average or power categories, but he has swiped 70 bases in 314 games in the majors. Grab him in deeper leagues if you need speed.
Pedro Ciriaco 2B/3B/SS, Padres
NL ONLY LEAGUES
(Yahoo: 1 percent owned)
Acquired from the Red Sox last week, Ciriaco figures to get regular playing time at shortstop with the Padres while Everth Cabrera recovers from a hamstring strain. The 27-year-old benefited from an unusually high .352 BABIP (batting average on balls in play) last season and doesn't offer much in the way of patience, but his speed and multi-position eligibility make him a no-brainer add in NL-only leagues. He could even make some sense in deeper mixed leagues if you are desperate for speed.
Andrew Brown OF, Mets
NL ONLY LEAGUES
(Yahoo: 0 percent owned)
Another part of the Mets' roster shakeup earlier this week, Brown was called up from Triple-A Las Vegas when Collin Cowgill was designated for assignment. The 28-year-old has scuffled in sporadic opportunities in the majors, but he has posted some big numbers in the minor leagues, especially against southpaws. The Mets are facing left-handed starters in three out of the next four games, so this is a perfect opportunity to give him a look in NL-only formats.
Alex Colome SP, Rays
AL ONLY LEAGUES
(Yahoo: 0 percent owned)
With David Price and Alex Cobb both sidelined, the Rays will call up Colome to make a spot start Saturday against the Yankees. The 24-year-old right-hander struck out seven while allowing an unearned run over 5 2/3 innings in his major league debut against the Marlins last month and owns a solid 3.07 ERA and 72/29 K/BB ratio in 70 1/3 innings over 14 starts with Triple-A Durham this season. While the Yankees should provide more of a challenge than the Marlins did, they aren't exactly scaring anyone right now. Colome is an excellent streaming option in AL-only leagues and could even make sense in some deeper mixed formats.
Jonathan Singleton 1B, Astros
AL ONLY LEAGUES
(Yahoo: 1 percent owned)
Acquired from the Phillies in the Hunter Pence deal back in 2011, Singleton is considered one of the top first base prospects in the game. The 21-year-old got off to a late start this season because of a 50-game suspension for a positive marijuana test, but he crushed the ball upon his return last month and recently earned a promotion to Triple-A Oklahoma City. With a .290/.393/.476 batting line in the minors, Singleton can hit for average and power and has shown the ability to draw walks. The Astros aren't going to let Carlos Pena stand in his way at first base, so make sure to have him stashed away. He figures to make his major league debut at some point during the second half.
