But the Mariners left fielder instead took all the blame himself for a pop fly that struck his glove, bounded off the wall then off his body into the crowd. The two-base error, which led to three unearned runs in a 6-3 loss to the Boston Red Sox on Monday night, was just one play of several the Mariners seemed to be a step or two behind.
