In a season that has been beset with injuries and continual roster shuffling, the Orioles picked up one of their more complete – and needed – wins Saturday afternoon with a 6-1 victory at Yankee Stadium, hours after suffering a heartbreaking defeat.

It couldn’t be without intrigue and lingering uncertainty, though. That would be contrary to this club’s unintended theme of the season: Nothing is ever easy.

Staked to a four-run lead and cruising through five innings Saturday, Orioles starter Bud Norris walked off the Yankee Stadium mound with right groin tightness after warming up in the bottom of the sixth.

Afterward, he said he was “pretty sore” and that it was too early to predict whether he’ll make his next start.

“I don’t want [the injury] to go on and I want to keep pitching for this team,” said Norris, who has had left groin discomfort in the past, but never on the right side. “[But] I’ve really got to take it a day at a time.”

Norris said he first felt a twinge while making a pitch to Francisco Cervelli in the fifth inning and told the athletic trainers once he came into the dugout. He was being monitored when he threw a warmup pitch before the sixth, grimaced and shook his head, prompting athletic trainer Richie Bancells, manager Buck Showalter and pitching coach Dave Wallace to run to the mound.

“He grimaces on every pitch. It might be the umpire, it might be the mound, it might be ... It's hard to know,” Showalter said. “We had a feel. He talked to us a little bit the inning before and it went pretty well, and then between innings there, we knew it was a possibility.”

Showalter believes the club shut down Norris before the discomfort worsened and is hopeful that he’ll pitch the second game of Friday’s split doubleheader as scheduled.

“He's getting an extra day next time out,” Showalter said. “We've got other options, but I'm hoping we caught it in time and kept it from developing into something with the groin that, obviously, you don't want long-term.”

It was an unfortunate development for Norris, who allowed just one run on three hits and two walks in five innings to pick up his fourth straight win, matching his career high for consecutive victories. Norris had never pitched in Yankee Stadium before, and he excelled before a announced sellout crowd of 47,165.

“My first start here in Yankee Stadium is a special day for me,” he said. “Yankee Stadium is Yankee Stadium, so I just wanted to keep going every five or six days and give this team an opportunity.”

Norris (7-5) has allowed just two earned runs in his past three outings, a span of 19 2/3 innings, and has lowered his season ERA to 3.62. He was on the verge of his third straight quality start before Ryan Webb was forced to enter in the sixth.

Instead of getting most of the day off, the relievers again had to be used heavily, with Webb, Brian Matusz and Tommy Hunter combining for four scoreless innings to secure the win for the Orioles (38-35). They are again one game behind the second-place Yankees (39-34) in the American League East, with Sunday’s series finale between Chris Tillman and Japanese sensation Masahiro Tanaka looming.
