This was a key matchup going into Game 1, and that shouldn’t change for the rest of the series.
The biggest difference heading into this next game is that the Yankee bullpen has only faced one batter, while the Orioles used five pitchers in the last four innings. A lot of pressure is going to be on Wei-Yin Chen to not only keep the score close, but also to save the bullpen from pitching too much.
It still remains to be seen how the Yankees will close out games without Mariano Rivera. His replacement, Rafael Soriano, pitched great in the regular season—but this is October, and no one did it better than Rivera.
Baltimore cannot afford another late-inning meltdown in Game 2. That goes especially for Jim Johnson, who, despite leading the AL with 51 saves during the regular season, pitched 0.1 innings of Game 1 and was rocked for five hits and five runs (four earned) in the ninth inning.
If the Orioles bullpen can't clean it up, they'll face the daunting task of having to win three straight in Yankee Stadium in order to advance.
