KFFL.com's Fantasy Baseball Diamond Market gives you candid reviews and ratings of fantasy baseball players making MLB news in your rotisserie or head-to-head baseball leagues. Are they trade bait or worth your FAAB dollars in your fantasy baseball games?

Jose Tabata, OF, Pittsburgh Pirates

Starling Marte (strained right oblique) hit the disabled list Sunday. Tabata was exiled to Triple-A Indianapolis in early July as the organization lost confidence in his performance and focus. He had sunnier skies in the Midwest, hitting .297 in 158 at-bats; he stole five bags, drove in 15 runs, crossed home plate 21 times and registered only 20 strikeouts.

The International League veteran still won't show much power in the near future. As long as he hits atop Pittsburgh's order, however, he'll be useful outfield filler - a few swipes, decent runs potential, a capable BA, maybe - especially if he carries over the improved contact he made at Triple-A.

Brett Anderson, SP, Oakland Athletics

Mr. Anderson returns

Anderson (Tommy John surgery) will start Tuesday against the Minnesota Twins, sources say, in what will be his first MLB outing since June 5 of last season. The southpaw threw a bullpen session Saturday for manager Bob Melvin and pitching coach Curt Young. They were giddy from what they saw, apparently. Anderson said he's touched 94 mph this year and that he aims to take it easy with his breaking pitches. The 18:5 K/BB he showed in his six rehab efforts eases some of the concerns showed by the accompanying 4.62 ERA.

Even then, any hurler starting his MLB road back after TJS is a risk, and that's multiplied in the first few outings of rust shake-off. The control that, along with generating bouncers, carries Anderson's approach won't be in full bloom. His work will probably be limited early on, too, thus also limiting his odds of registering victories.

Still, he's worth a low-investment grab for those who need SP depth; his favorable pitching environment actually has a semblance of a backing offense, and having the 24-year-old dishing out several useful outings can go a long way this time of year.

Ryan Lavarnway, C, Boston Red Sox

After Boston dealt purported mobile phone rabble-rouser Kelly Shoppach last week, time opened up behind the plate for this youngster. Jarrod Saltalamacchia looked like an All-Star early on but is hitting .174 in 46 August at-bats; Boston will look to split time more evenly between their two receivers.

The 25-year-old logged a respectable .295-8-43 in 319 Triple-A at-bats before being plucked from Pawtucket earlier this month. His defense has held back the promise provided by his lumber, but his improving relationship with Boston's starters will go a long way in maximizing Lavarnway. He also earned praise for his PawSox work behind the dish.

Power is the most secure thing - at least, as much as it can be for a still-growing catcher - he'll offer; his 6-foot-4, 225-pound frame aids the possibility of it arriving for fantasy leaguers soon. He still whiffs a bit too much, though, so he could actually yield Salty-like numbers, for good and bad. Not that two-catcher owners would complain.

Johnny Giavotella, 2B, Kansas City Royals

The Chris Getz experiment didn't last long; he landed on the DL with a broken left thumb. Giavotella will play up to six contests per week; KC wants to see what he can give them as an everyday player.

For the month he was in the bigs previously this year, he hit just .217 in 21 contests. He fared much better in returning to the Pacific Coast League, running off a .323/.404/.472 line, which included 10 homers, in 362 at-bats for Triple-A Omaha.

It's hard to expect the 25-year-old to provide the fence-clearing this season with the big club. In 81 plate appearances for KC this season, he has posted a 30.2 percent liner rate, so at least he's fitting the contact-leaning profile in his infancy. Though he stole seven bags on the farm, he's not a speedster, so if he doesn't run, he could wind up a boring acquisition. There's a smidge of hope he can be useful in 2013 if he shows progress.
