Eric Gagne sat in front of his locker, his head down and his shoulders sagging. He wasn't the one who gave up the game-winning home run to Kevin Millar, yet the struggling reliever heaped all the blame for Boston's latest defeat squarely upon himself. Millar hit a three-run homer in the 10th inning after Miguel Tejada tied it with a shot off Gagne in the eighth, leading the Orioles past the skidding Red Sox 6-3 Sunday. It was the fourth loss in six games for the Red Sox, whose lead over the Yankees in the AL East shrunk to four games -- Boston's smallest margin since May 1.
