The Orioles opened a 13-game stretch against American League East opponents Monday night against the Boston Red Sox at Camden Yards.

While both teams have been inconsistent so far this season, the defending World Series champion Red Sox have struggled mightily in the past week.

Right-hander Bud Norris recorded his best start since joining the club last July, tossing eight scoreless innings and holding Boston to just three hits as Baltimore handed the Red Sox their sixth loss in seven games with a 4-0 win in front of an announced 19,729 at Camden Yards.

After the Orioles were forced to account for 62 / 3 innings with their bullpen Sunday afternoon, they needed a deep start from Norris. He provided just that, matching his career-long outing while striking out six batters and walking three in the 2-hour 21-minute game.

The Orioles (32-30) backed Norris with three home runs off Boston starter Jake Peavy, including right fielder Nick Markakis’s two-run blast in the fifth inning that landed on the right-field flag court.

Machado apologizes

After apologizing to his Orioles teammates during a players-only meeting Monday, third baseman Manny Machado made a public apology for his actions in Sunday series finale against the Oakland Athletics.

Machado said he allowed his “emotions to get the best of me” when he let go of his bat and it flew down the third base line, prompting both benches and dugouts to clear for the second time in the three-game series.
