The Texas Rangers' flagging starting pitching took another hard hit on Thursday night in a 6-0 loss to Boston.

Alexi Ogando allowed a career-high four homers - all on poorly placed fastballs - in only four innings. It marked the second time in Ogando's last four starts that he failed to go beyond the fourth inning.

Boston won the final three games of the series by a combined score of 30-7. The Red Sox hit nine homers in those games.

"You've got to pitch to stay in the game with them,'' Rangers manager Ron Washington said. "It's that simple.''

The loss cut the Rangers' lead in the American League West to two games over the Los Angeles Angels . The Rangers open a three-game series against the Angels on Friday night at Rangers Ballpark in Arlington.

"We'll respond,'' said Michael Young, who had one of only three hits by the Rangers. "We've been tested before, and we've always answered the bell.''
