Pitchers

Brian Matusz, SP, Baltimore Orioles

New skip, rediscovered zip

Don't look now, but the Orioles' prized southpaw has been outstanding in August (3-1, 2.32 ERA, 1.06 WHIP, 3.33 K/BB). Maybe it's just coincidence that his streak began right after Buck Showalter took over. Matusz has been very stingy with free passes and has recently upped his ground-ball service.

Matusz is throwing all his offerings for strikes. Results: He's keeping hitters off-balance, and he's pitching with more confidence. He still has solid K potential, too. Showalter has the O's playing to win, making them a sneaky source of late-season fantasy value.
