Baltimore: RHP Jake Arrieta threw eight shutout innings Wednesday at Yankee Stadium, but manager Buck Showalter decided not to let him complete the shutout bid. Arrieta had thrown 111 pitches, and Showalter admitted he considered sending him out for the ninth. "Sure, but this is a guy coming off surgery," Showalter said. Arrieta had a right elbow operation last August. ... 1B Nick Johnson, who began his big-league career with the Yankees, finally got his season on track this week against his former team. After entering the series 0-for-26 on the year, he went 3-for-9 in the Bronx.
