Normally, a blowout win against the New York Yankees is celebrated with abandon at Camden Yards. Add in that Monday’s 11-3 victory separated the Baltimore Orioles and Yankees even further in the American League East race and that one of the offensive heroes was beleaguered slugger Chris Davis, and you’d have almost the perfect scenario for Orioles fans.

Except that that feel-good vibe took a hard tumble in the third inning when 22-year-old third baseman Manny Machado collapsed in the batter’s box after a swing and had to be helped off the field. The early diagnosis is a sprained right knee — it was the left knee he injured last season — and he’ll be re-evaluated Tuesday.

The injury potentially could be deflating for the first-place Orioles, who have played the past two games without shortstop J.J. Hardy. He is dealing with a sprained left thumb. Given the current uncertainty regarding the left side of the infield, Baltimore likely will have to summon a player from Class AAA Norfolk in case there is a need Tuesday.

Machado’s situation dampened an otherwise explosive night for the Orioles (68-50), who moved to seven games ahead of the third-place Yankees (61-57).

Playing in an intermittent drizzle before an announced 34,018, Baltimore rebounded from Machado’s injury with three homers, including two-run shots by Davis and Nelson Cruz and a three-run laser from rookie Jonathan Schoop.

Davis was initially on the bench against left-hander Chris Capuano (1-3). He was summoned in the top of the fourth to play third base. In the fifth, in his first at-bat replacing Machado, Davis slugged a full-count slider to right for a 4-3 lead. It was his 21st home run of the season.
