This after he set down Mike Lowell, J.D. Drew and Sean Casey in order in the fourth inning, Lowell on a popup, Drew on a broken-bat grounder. Actually, the decision was made this morning, but Clayton wasn’t told about it until Honey (that’s clubhouse speak for Rick Honeycutt) told him just after he came out of the game that it was probably going to happen. Then, just after the game, DeJon Watson popped into the clubhouse to tell him it was official. Joe Torre wouldn’t go so far as to say that Clayton is now competing for a spot on the opening-day roster, and Esteban Loaiza took a step toward cementing the fifth spot in the rotation today with three shutout innings during which he allowed only two hits. But Clayton clearly is in the running now to be in the majors sometime this season, possibly even before September. … Matt Kemp hit a three-run HR, against the wind and over the berm in left, off Dice-K in the first inning. Dodgers added a manufactured run in the eighth when JP (that’s clubhouse speak for your favorite left fielder) walked, and pinch runner George Lombard stole second, took third on a Lucas May groundout and trotted hom on a wild pitch by some Boston pitcher named Hansack. … Dodgers go to 5-6-1. At the Orioles tomorrow
