Nah, all he did was beat the defending World Series champion New York Yankees in Baltimore.

Arrieta pitched six innings of four-hit ball, and the Orioles ended their 10-game losing streak against the Yankees with a 4-3 victory last night.

The Yankees’ Alex Rodriguez left the game after the first inning. The premature exit occurred four days after he was pulled from a game against Toronto with groin tightness.

“The last two days it has felt the exact same way and once it got warm it was OK. Today, it cramped up right before batting practice,’’ Rodriguez said.

Rodriguez intends to see the team doctor today, but said, “I hope I play.’’

Although Arrieta’s arrival didn’t get a fraction of the attention that Stephen Strasburg received in Washington Tuesday, there was still a buzz at Camden Yards — and more fans in attendance (27,064) than in each of the previous two games of the series.

Royals 9, Twins 8 — Wilson Betemit hit solo home runs from both sides of the plate and Joakim Soria picked up his 14th save in a hairy ninth inning and visiting Kansas City got by Minnesota.

Betemit hit one lefthanded in the second inning after Mitch Maier’s two-run shot to help the Royals jump out to an 8-1 lead, then hit one from the right side in the ninth. It was the sixth time in franchise history that a player has homered from both sides of the plate in the same game.

Reds 7, Giants 6 — Brandon Phillips had four hits, including a two-run triple in the eighth inning that rallied host Cincinnati to yet another comeback win.

Phillips’s triple off Guillermo Mota (0-2) tied it at 6. Joey Votto’s single up the middle gave the Reds their 12th win in their final at-bat, the most in the majors.

Lefthander Arthur Rhodes (2-1) retired five batters for the win. Francisco Cordero retired the side in the ninth, getting his 17th save in 21 tries.

Blue Jays 3, Rays 2 — Brett Cecil won his fifth consecutive start, Alex Gonzalez homered and drove in two runs, and Toronto edged Tampa Bay in St. Peterburg, Fla.

Athletics 6, Angels 1 — Trevor Cahill allowed one run in a career-high eight innings to win his fourth straight start and host Oakland beat nemesis Ervin Santana.

The A’s struck for two runs in the fourth and three in the fifth against Santana (6-4), who came into the game with an 11-2 record and a 1.50 ERA in 19 career appearances against Oakland.

Brewers 5, Cubs 4 — Carlos Gomez raced home from first base on a sacrifice bunt and throwing error in the 10th inning and host Milwaukee held off Chicago in a wild contest.

Padres 4-2; Mets 3-0 — Jonathon Niese pitched a one-hitter for his first career complete game and New York shut out San Diego last night for a doubleheader split at Citi Field. Mat Latos outpitched Johan Santana in the opener, and San Diego stopped New York’s nine-game home winning streak.

Astros 5, Rockies 4 — Roy Oswalt struck out nine, Humberto Quintero homered, and Houston won its third straight, beating Colorado in Denver.

White Sox 3, Tigers 0 — John Danks pitched seven innings of one-hit ball, and Omar Vizquel homered and had a suicide-squeeze bunt to help Chicago blank visiting Detroit.
