The Orioles are used to playing long games. In 2012, they played many long ones, but this year, Thursday’s night was the longest yet.

By the time it was over, the Orioles used seven pitchers, and needed some bullpen help for the weekend. Their starter, the prized rookie, Kevin Gausman was sent to Norfolk so that a fresh arm could be brought in.

Not that Gausman pitched badly. He allowed two runs and six hits in 5 1/3 innings, but by the time Nick Markakis scored with the winning run, the rookie was a footnote.

Chris Davis slapped a short opposite-field single to short left, just out of the reach of shortstop Stephen Drew, and the Orioles had a 5-4 win in 13 innings over the Boston Red Sox.

Many of the 20.098 who ignored dire weather forecasts were still on hand at the end of the game, and they saw some excellent relief pitching.

Orioles’ pitchers did not walk a batter in 13 innings, and five relievers didn’t allow a hit in the last six innings.

“You definitely want to win those games, especially when you’re using all your guys and you’re staying close. They threw everybody they had at us and we did the same with them,” Davis said.

Gausman’s first big league victory will have to wait. He pitched gallantly on Thursday night, working into the sixth inning with the lead.

“I think I did a pretty good job just kind of going at some guys and moving their feet and making sure they weren’t too comfortable in the box. And so for that was more important than anything.” Gausman said.

T.J. McFarland, the seventh Orioles pitcher, got the win, pitching a scoreless 13th. McFarland (1-0) got his first major league win.
