Greg Holland RP, Royals
MIXED LEAGUES
(Yahoo: 34 percent owned, ESPN: 27.1 percent)
After the Royals traded closer Jonathan Broxton to the Reds this week, manager Ned Yost quickly came out and named Holland as his replacement. The hard-throwing right-hander is certainly worthy of the opportunity, posting a 3.17 ERA and 153 strikeouts over 119 1/3 innings in the majors. One concern is that has found himself behind in the count a lot this year, which has seen his walk rate jump from 2.9 BB/9 last year to 5.1 BB/9, but there's no question that he has the kind of swing-and-miss stuff you look for in a closer. Give him a look in all mixed formats.

Ryan Ludwick OF, Reds
MIXED LEAGUES
(Yahoo: 18 percent owned, ESPN: 34.2 percent)
I'll admit it, I groaned when the Reds signed Ludwick over the winter. What can I say, I was hoping the Reds would give Chris Heisey a longer look in left field. However, I'm ready to admit that I missed the boat on this one. After amassing six home runs in June and seven in July, Ludwick kicked off August by going 3-for-4 with a homer and four RBI against the Padres. The 34-year-old outfielder now has 19 home runs on the year and is on pace for his first 30-homer season since he slugged 37 in 2008 as a member of the Cardinals. Playing half his games in the hitter-friendly Great American Ballpark, the possibly can't be ruled out.

Brandon McCarthy SP, Athletics
MIXED LEAGUES
(Yahoo: 44 percent owned, ESPN: 45.6 percent)
McCarthy was tagged for six runs over 3 2/3 innings on Monday in his first rehab start with Triple-A Sacramento, but the important part is that his shoulder felt fine. He's scheduled to make another rehab start Saturday, after which he should be cleared to rejoin the Athletics' rotation. The 29-year-old right-hander has been excellent between DL stints this season, posting a 2.54 ERA, 1.21 WHIP and 52/19 K/BB ratio over 78 innings, so he should be stashed away in most mixed leagues.

Denard Span OF, Twins
MIXED LEAGUES
(Yahoo: 20 percent owned, ESPN: 36.4 percent)
Span hasn't received much attention, probably because he doesn't hit for power, so you might be surprised to learn that he's hitting .414 (29-for-70) since the All-Star break. Among players with at least 50 plate appearances, only Andrew McCutchen, Yoenis Cespedes, Buster Posey and David Freese have a higher batting average during the same time span. The 28-year-old center fielder currently holds a 10-game hitting streak, which has increased his batting average from .275 to .296 overall. It would be nice if he ran more, but at least he's getting on base and scoring runs. Use him while he's hot.

Andrew Bailey RP, Red Sox
MIXED LEAGUES
(Yahoo: 41 percent owned, ESPN: 15.9 percent)
Look who is finally on the comeback trail. Sidelined all season following thumb surgery in early April, Bailey tossed a scoreless inning Wednesday in his first rehab appearance with Boston's Gulf Coast League affiliate. He'll likely need several more appearances before being activated, but there's a pretty good chance he'll be in the Red Sox bullpen before the end of the month. Alfredo Aceves has been excellent since a couple of implosions in early April, but don't forget how valuable he was a multi-inning reliever last year. Bailey is worth a stash if you need saves.

Paul Maholm SP, Braves
MIXED LEAGUES
(Yahoo: 38 percent owned, ESPN: 38.2 percent)
The Braves were unable to land Ryan Dempster from the Cubs, but their backup plan wasn't too shabby. Maholm has a solid 3.74 ERA and 81/34 K/BB ratio over 120 1/3 innings this season, including a microscopic 1.00 ERA over his last seven outings. I don't think he's a must-start every time out, even with the recent success, but he certainly gets a boost in value now that he's no longer playing for one of the worst teams in the majors. He'll face the lowly Astros this weekend, so he makes for an excellent streaming option at the very least.
Carlos Gomez OF, Brewers
MIXED LEAGUES
(Yahoo: 28 percent owned, ESPN: 48.6 percent)
While Gomez remains one of the most frustrating talents in the game, the speedy center fielder is doing enough to warrant attention in deeper mixed leagues. The 26-year-old already has a career-high nine homers to go along with 20 stolen bases, his highest such total since he swiped 33 bags in 2008 as a member of the Twins. He's been especially hot recently, batting .321 (17-for-53) with four home runs, 10 RBI, nine stolen bases and 14 runs scored over his last 16 games. Gomez still has a pretty terrible approach at the plate, so he doesn't deserve a particularly long leash, but his speed-power combo has value.
Chris Carter 1B, Athletics
MIXED LEAGUES
(Yahoo: 6 percent owned, ESPN: 5 percent)
Carter is beginning to silence those who dismissed him as a Quad-A hitter. The 25-year-old is hitting .275/.405/.652 with eight home runs, 17 RBI and a 1.057 OPS in in 84 plate appearances since being called up from the minors in late June. While he has struck out 21 times, he has also drawn 17 walks. A lot can happen in a small sample, but Carter has mashed in Triple-A for a long time and two brief (albeit awful) stints in the majors in 2010 and 2011 shouldn't close the book on his long-term prospects. Those looking to fill a CI (corner infielder) spot in a deeper mixed league can afford to gamble.
Kris Medlen RP/SP, Braves
MIXED LEAGUES
(Yahoo: 7 percent owned, ESPN: 7.8 percent)
Medlen made his first start of the season Tuesday against the Marlins, allowing just one run over five innings while striking out three and walking just one. Tommy Hanson was placed on the disabled list this week with a lower back strain, which means Medlen should at least get a couple more turns in the rotation. The 26-year-old right-hander is plenty valuable out of the bullpen, but don't forget that he posted a quality 3.86 ERA and 62/16 K/BB ratio in 14 starts with the Braves back in 2010 prior to undergoing Tommy John surgery. He's worth owning for the short-term, especially with a start against the Astros this weekend.
Domonic Brown OF, Phillies
MIXED LEAGUES
(Yahoo: 4 percent owned, ESPN: 0.8 percent)
The Phillies traded Hunter Pence to the Giants and Shane Victorino to the Dodgers this week, so Brown will finally get his chance to sink-or-swim in the big leagues. Between the Phillies trying to change his swing, a broken hamate bone during spring training last year and a bum knee this year, the 24-year-old hasn't had much luck since being ranked as the game's No. 4 prospect by Baseball America prior to the 2011 season. The good news is that he swung the bat well at Triple-A after returning from the knee injury last month, hitting .362 (17-for-47) with three doubles and a home run in 13 games. Brown may never be the fantasy monster many predicted he would be, but he's still plenty intriguing. Give him a shot if you have some roster flexibility.
Mike Olt 3B, Rangers
MIXED LEAGUES
(Yahoo: N/A, ESPN: 0 percent)
We learned late Wednesday night that the Rangers were promoting Olt to the majors. The decision comes as a bit of a surprise, as Olt has never played above Double-A and there's no clear path to playing time. We can rule third base out due to the presence of Adrian Beltre, so that means he'll likely split time between first base, the outfield and the DH spot. The 23-year-old has played 13 games at first base and three in right field this year. The Rangers probably don't want one of their top prospects sitting on the bench, so the struggling Michael Young may have to accept a diminished role. Olt strikes out quite a bit, but he has big-time power from the right side of the plate, amassing 28 homers in just 95 games this season. He's a must-add in deeper formats, but those in shallow leagues should monitor the situation until there's more clarity on his role.
Dan Straily SP, Athletics
MIXED LEAGUES
(Yahoo: N/A, ESPN: N/A)
I included Straily under my AL-only names to watch two weeks ago, but now that the Athletics are calling him up to the big leagues, those in mixed leagues should pay attention. The 23-year-old right-hander has been one of the most surprising stories in baseball this season, posting a 2.60 ERA and 175/37 K/BB ratio in 138 1/3 innings over 22 starts between Double-A Midland and Triple-A Sacramento. Nobody has more strikeouts this year and that includes all major league pitchers. He also saw zero decline in his strikeout and walk rates after his promotion to Triple-A. Pretty impressive considering he was pitching in the Pacific Coast League. Straily isn't available in Yahoo! and ESPN.com leagues yet, but assuming he gets a rotation spot, get ready to pounce.
Patrick Corbin SP/RP, Diamondbacks
NL ONLY
(Yahoo: 1 percent owned, ESPN: 0.1 percent)
After failing to add a starting pitcher at the trade deadline, the Diamondbacks decided to remove Josh Collmenter from the rotation and replace him with Corbin. So far, so good. The 23-year-old left-hander allowed just two hits and two walks while striking out five over six scoreless innings in a win over the Dodgers on Wednesday. Corbin throws strikes, works in the low-90s with his fastball and his slider and changeup are both average or better pitches. Trevor Bauer and Tyler Skaggs may have more long-term upside, but Corbin is a must-own in NL-only leagues as long as he has a rotation spot.
Welington Castillo C, Cubs
NL ONLY
(Yahoo: 0 percent owned, ESPN: 0 percent)
The Cubs traded Geovany Soto to the Rangers this week, so Castillo and Steve Clevenger figure to share playing time behind the plate the rest of the way. Clevenger won the backup catcher job during spring training, but Castillo was probably better off playing every day in the minors, anyway. The 25-year-old slugged eight homers in 49 games between Double- and Triple-A this year and had 15 in 61 games last year, so his pop could be pretty useful down the stretch. Castillo bats right-handed, so he could be at a disadvantage if Dale Sveum uses a strict platoon, but he's worth adding in two-catcher leagues.
Brett Wallace 1B, Astros
NL ONLY
(Yahoo: 1 percent owned, ESPN: 0.1 percent)
I was a bit surprised that Wallace wasn't called up from the minors immediately following the Carlos Lee trade early last month, but better late than never, I suppose. The former top prospect went 3-for-4 with a pair of homers in Wednesday's loss to the Brewers and should get regular at-bats moving forward. We obviously have to take Pacific Coast League numbers with a grain of salt, but the 25-year-old had 16 home runs in 86 games with Triple-A Oklahoma City this season. NL-only owners can afford to see if there's some kind of post-hype breakout going on.
Josh Vitters 3B, Cubs
NL ONLY
(Yahoo: 0 percent owned, ESPN: 0.1 percent)
With Cubs general manager Jed Hoyer indicated earlier this week that Vitters will likely be called up from Triple-A Iowa in the near future. Ian Stewart is done for the season following wrist surgery and Luis Valbuena has been terrible, so it's a logical move as the Cubs evaluate potential long-term pieces. Vitters isn't a strong defender at third base, but he's hitting .296/.351/.502 with 16 home runs and an .853 OPS in 107 games with Triple-A Iowa this year. And while he's hardly a patient hitter, he has already drawn 30 walks this year, his most in a full season in pro ball. It's not much, but it's progress. Go ahead and stash him away.
Casey McGehee 1B/3B, Yankees
AL ONLY
(Yahoo: 5 percent owned, ESPN: 1.9 percent)
McGehee landed in a pretty good situation this week, as he was traded from the Pirates to the Yankees in exchange for reliever Chad Qualls. He's currently filling in at first base while Mark Teixeira nurses a wrist injury and should eventually split playing time with Eric Chavez at third base until Alex Rodriguez is ready to return from a fractured hand. Of course, Chavez is no iron man, so there's real opportunity here. McGehee's production has fallen off dramatically over the past two seasons, but his pop makes him worth owning in AL-only leagues.
George Kottaras C, Athletics
AL ONLY
(Yahoo: 1 percent owned, ESPN: 0.1 percent)
Martin Maldonado impressed while Jonathan Lucroy was sidelined with a fractured hand, so the Brewers designated Kottaras for assignment last week. However, it didn't take long for him to find a new home, as he was traded to the Athletics just a couple of days later. Only Clint Barmes has a lower OPS than Kurt Suzuki (.536) among player with at least 250 plate appearances this season, so Kottaras figures to see a good amount of playing time down the stretch. His patience and pop should be useful in two-catcher formats.
Eric Thames OF, Mariners
AL ONLY
(Yahoo: 1 percent owned, ESPN: 0.3 percent)
Thames and Travis Snider battled for the Blue Jays' starting left field job during spring training, but now both of them have landed with new organizations. The 25-year-old flopped with the Jays earlier this year, but he collected 47 extra-base hits in just 95 games last year. Sure, Safeco Field isn't exactly the best home hitting environment, but at least it's more favorable for left-handed batters than right-handed batters. In fact, it's not far off from Rogers Centre in that respect. Thames should get a long look in the Mariners' outfield, so he's worth a flier.
Johnny Giavotella 2B, Royals
AL ONLY
(Yahoo: 1 percent owned, ESPN: 0 percent)
What else does this guy have to do to get another shot in the majors? After hitting .368 with five home runs and 28 RBI at Triple-A Omaha in July, the 25-year-old second baseman went 2-for-4 with three RBI on Wednesday. Sure, he batted just .247 with a .649 OPS in 46 games with the big club last year and underwhelmed during a brief stint earlier this season, but Yuniesky Betancourt and Chris Getz aren't doing much to stand in his way. Let's hope the Royals come to their senses soon.
