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?

Brandon Belt heating up

Belt's story with the San Francisco Giants is old: Last year he was frequently on the shuttle between SF and Triple-A Fresno, and with Aubrey Huff and Brett Pill around, he's been hard-pressed to find consistent ABs in the Bay Area.

Things are looking up for the 24-year-old, though; Huff has dealt with anxiety and now a knee injury, and Pill is toiling in the minors. Bruce Bochy, who has been hesitant to put Belt in the lineup against lefties, recently committed to giving him more at-bats, but as Henry Schulman notes, we've heard it before.

Although he has plenty to improve on - mostly his approach against southpaws - he finally made an adjustment suggested by coaches. Since adopting the new upright, open stance, he's shown improvement in June (.269-3-10), including homers in each of his last three games. Belt has also fanned five times and walked five times this month.

The BA may be slow to come, but his power stroke is legitimate. He'll yield more good results if Bochy is true to his word and sticks with him. For now, ride the hot streak.

Endy Chavez heading back to the DL

Chavez wasn't able to avoid his second trip to the infirmary, landing on the 15-day DL, this time with a right hamstring strain. The injury isn't serious, and he expects to be back when he's eligible.

Chavez has the skills - good contact, speed - to be effective as outfield depth in leagues with enough outfield spots. He's not making as much contact as he usually does, as his .171/.202/.219 slash line would suggest, but it could be attributed to the injuries and a lack of consistent at-bats. If he can stay healthy upon his return, he stands a chance to improve his numbers and offer you some stolen bases. Age isn't in his favor, though.

In the meantime, Steve Pearce and Steve Tolleson will flank Adam L. Jones in the corner outfield spots. One of them, likely Pearce, has the opp to stick around even after Chavez heals with no return date in sight for Nolan Reimold (neck).

Pearce and Tolleson shouldn't excite fantasy owners, except for desperate AL-only fly-catcher seekers. With interleague play in full swing and B'more headed to NL parks, Chris Davis, Wilson Betemit or even Robert Andino could take PT away from these two, too.

Texas Rangers throw Justin Grimm into rotation

Alexi Ogando (strained right groin) landed on the DL Tuesday, and the Rangers were in need of another starter since Roy Oswalt isn't quite ready and Derek Holland (illness, weak shoulder) is in the process of strengthening his arm and getting healthy.

Michael Kirkman will be used in mop-up work, and skipper Ron Washington valued Robbie Ross too much in the bullpen. Instead, Texas recalled Grimm to make his major league debut Saturday versus the Houston Astros.

Grimm went 8-3 with a stellar 1.87 ERA to go along with 67 K's and just 14 walks in 77 innings over 13 starts with the RoughRiders. He has the build of a major league pitcher, but he hasn't tasted action at the minors' top level, and his mechanics could use some polish.

GM Jon Daniels said Grimm could be used for more than just a spot start, but with Oswalt waiting in the wings - although his 7.71 ERA in the minors isn't pretty - Grimm isn't expected to stick around for long.
