Scott Kazmir - If you can afford to take a hit in the WHIP department, this kid can help you out. Seriously. And believe it or not, I've seen him in FA in several leagues I've checked into throughout the year. In the last month, Kazmir has K'd 42 in 38.1 IP, notched 3 Wins, and carried a 2.58 ERA. In H2H his WHIP may be somewhat of a liability, but if you can afford it, reap his benefits in other areas.
Joey Gathright - 22/71 (.310) in the last 30 days, with 6 swipes, 11 Runs and 7 RBI. He's probably the best source for cheap steals in FA (if he's even still there), and now that he appears to be hitting alright, I've considered him a rosterable player in fantasy.
Gary Matthews Jr. - If you're a ride the hot streak kinda guy, then you may want to hop on the train before it derails at some point. 19 R, 7 HR, 22 RBI, and 4 SB while carrying a .342 BA in the last month. What's YOUR last OF done over that span? What do you expect from the rest of the season from him? He's a worthy gamble, if you're even still calling him that.
I'll update every so often, with my opinions, if this thread keeps kicking.
