Cooked quickly

Colorado starter Aaron Cook continues to struggle out of the gate. For the third time in four starts, Cook gives up his first run in the first inning. The Dodgers scored two and had the bases loaded before Cook even got the first out. He stranded those runners on a couple of come-backers to the mound, the second of which he turned into a 1-2-3 double play. To his credit Cook got through the first on just 19 pitches. If he can find his stuff the Rockies offense might get him back in the game.

Cook's issues stem from a problem with his delivery, which has flattened out his sinker.

Fantasy Impact: Cook made the All-Star Game last year thanks to his sinker. It's one of the best in the game when it's right, but it's nowhere closer to where he needs it to be. Until he finds the pitch again, Cook is just an also ran in terms of fantasy play.

Washburn sinking in

Hello, Jarrod Washburn. The Seattle southpaw, an afterthought in the fantasy baseball world, lifted his left arm to the heavens on Thursday night, and each time that arm came down a sinking fastball floated around and under the bats of miffed Minnesota batters. Washburn's new pitch got him through eight innings of five-hit baseball and earned the Seattle Mariners a 2-0 win.

Fantasy Impact: Sinkerballers pose an intriguing value in fantasy play. Typically guys like Chien-Ming Wang and Aaron Cook keep their teams in the game and maintain low ERAs, but they're not going to strike people out. Washburn never did, and in Seattle he's unlikely to win. That said, a pitcher who can get people out and pitch deep into games as Washburn did Thursday always has a chance. That means this old lefty with a new pitch can pay dividends at the back end of most fantasy staffs.
