(AP) — Chris Davis singled home the tiebreaking run with two outs in the 13th inning, giving the Baltimore Orioles an exhausting 5-4 victory over the Boston Red Sox in the opener of a four-game series between AL East contenders.
Danny Valencia homered for the Orioles, who moved into second place and within 2½ games of Boston. Baltimore won despite leaving 16 on base and going 4 for 14 with runners in scoring position.
With two outs in the 13th, Nick Markakis drew a walk from Alex Wilson (1-1). Adam Jones singled and Davis followed with an opposite-field pop that landed in front of left fielder Daniel Nava.
T.J. McFarland (1-0) pitched the 13th to earn his first major league win. The Orioles used seven pitchers, none of whom issued a walk.
