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?

Zach Britton, SP, Baltimore Orioles

He's probably past the shoulder woes that robbed him of his first half of the season. Britton has given up 17 hits, three runs and five walks, with 21 strikeouts, in his last three starts (21 2/3 stanzas). He won all three.

Arias on Bochy's friends list

It's doubtful that the left-hander is owned widely, thanks to his 4.80 ERA and 1.53 WHIP in eight MLB starts this season. The O's optioned the left-hander to the minors immediately following his latest start, a 10-K masterpiece, on Thursday, so perhaps a novice owner who happened to jump on his bandwagon has released or will dump him.

Now that Britton, 24, is healthy and has a couple of months of baseball under his belt this year, he's in top form, and he appears to have learned a thing or three along the way. This is the same pitcher who, in his first taste of The Show, opened 2011 by going 5-2 with a 2.14 ERA and 33 strikeouts in his first nine games (59 innings).

The sinkerballer is talented, and when he's on, he's hard to beat. And, don't worry, he'll be back.

Joaquin Arias, 3B/SS/OF, San Francisco Giants

The Giants are desperate for some offense. Gregor Blanco, for example, has failed to provide much of it. Arias has batted .285 with four home runs and four stolen bases in 282 plate appearances this season and has hit .429 with three round-trippers in 56 August at-bats. He will play often, going forward.

This according to Bruch Bochy, anyway. The manager will probably play him in left field to get him in there. The resurgent Arias hit pretty well for stretches when he filled in for Pablo Sandoval earlier this season and is a .280 hitter lifetime. His career .389 slugging percentage confirms that he won't go for extra bases frequently, and he's never really put the speed that he displayed in the minors to use in the bigs.

Arias is Bochy's flavor. As long as he continues to rap out several hits a week, he'll probably remain that way. He may contribute to your bottom line, but only a little, and his PT will always be at risk.
