SEATTLE, May 30 (UPI) -- Doug Fister threw 7 1/3 strong innings Monday, earning his first win in a month while helping the Seattle Mariners to a 4-3 win over Baltimore.
Fister (3-5) notched a victory for the first time since April 30, a span of five starts. He held the Orioles to three runs on seven hits, walking one and striking out nine as the Mariners moved above .500 (27-26).
The right-hander ran into trouble in the eighth when Robert Andino, Felix Pie and Nick Markasis all singled to pull Baltimore to within 4-2.
Jamey Wright came in to pitch and yielded an unearned run when Vladimir Guerrero reached on a fielding error by Chone Figgins. But Matt Wieters grounded into a fielder's choice and Aaron Laffey induced Luke Scott to ground out, ending the inning.
Brandon League produced a scoreless ninth to nail down his 14th save for Seattle, which benefited from two consecutive bases-loaded walks issued by O's starter Jake Arrieta (6-3) in the third inning.
Mark Reynolds hit a solo homer for Baltimore.
