Chris Davis drove in two runs for the Orioles, who used the same formula that got them into the postseason for the first time in 15 years: a magnificent bullpen and an ability to win tight games. Baltimore was 29-9 in one-run decisions during the regular season and 74-0 when leading after seven innings.

Major league saves leader Jim Johnson, roughed up for five runs in a Game 1 loss, pitched a perfect ninth to close it out.

Game 3 of the best-of-five series will be held at Yankee Stadium on Wednesday.
