Colton Cowser hit a tiebreaking double in the ninth inning after helping to throw out the potential go-ahead run in the eighth, lifting the surging Baltimore Orioles to a 3-2 victory over the Philadelphia Phillies on Monday night.
Ryan Mountcastle and Jordan Westburg went deep for the AL-East leading Orioles, who have won 13 of 16 games. Baltimore moved 2 1/2 games ahead of idle Tampa Bay.
Nick Castellanos and Kyle Schwarber drove in runs for the defending NL champion Phillies. Philadelphia has lost five of six.
Cowser entered as a defensive replacement for Aaron Hicks in the third inning after Hicks was hurt making a diving catch.
