For years, the Yankees had been able to rely on their series against Baltimore to improve their record and pad their statistics. But the Orioles are leaving Yankee Stadium this week with two victories in three games and some momentum in the American League East.

A 5-0 loss to the Orioles on Wednesday night brought with it a host of other unwelcome developments for the Yankees.

Ivan Nova lost, to snap a streak of 15 straight victories; the Yankees’ hitters had another anemic performance at the plate, this time against Baltimore starter Jake Arrieta, who lasted eight innings; and Eric Chavez may have sustained a concussion while trying to make a diving catch in the fifth inning.

The defeat was a fitting bookend to a series that went well for the surprisingly hot Orioles. One of the loudest cheers of the night came when the scoreboard showed that the Rangers were leading the Washington Capitals in their playoff game.
