– The Baltimore Orioles’ 4-0 loss to the Los Angeles Angels on Friday night might have come at a greater price.

The Orioles’ top offensive weapon of the opening month of the season, first baseman Chris Davis, hobbled off the field in the fifth inning with what the team initially diagnosed as a right-knee injury.

While running out a grounder to third, Davis — who was named the American League player of the month a day earlier — came up lame after running past the first-base bag. Replays showed that his right knee appeared to buckle as his right foot touched the first base bag mid-stride.

He limped into the Orioles dugout down the first-base line and down the stairs toward the visiting clubhouse grasping to the stair railings, unable to put weight on his right leg. He will be evaluated further.

The Orioles are now 5-4 on their 11-game west-coast road trip to Oakland, Seattle and Anaheim, but losing Davis for any significant amount of time would prove to be a great loss.

To make matters worse, Orioles starter Miguel Gonzalez, who allowed just six hits over six innings and 80 pitches, left the game with a blister on his right thumb.

Davis, who has been one of baseball’s top run producers through the season’s first five weeks, entered the game hitting .337 with a .438 on-base percentage and .704 slugging percentage and was tied for the AL lead with nine homers while leading the team with 29 RBI.

The Orioles (17-13) fell victim to Angels left-hander Jason Vargas, who allowed just three hits in a complete-game shutout.
