SEATTLE — Bryan Woo pitched seven strong innings, and the Seattle Mariners capitalized on two hit batters in the sixth to score twice and beat the San Francisco Giants 4-3 on Sunday.
The game was tied at 2-2 when Randy Arozarena was hit by a pitch leading off the sixth. Justin Turner singled and Jorge Polanco was hit by a pitch to load the bases.
Arozarena scored when Mitch Haniger hit into a double play, and Josh Rojas' single drove in another run to make it 4-2.
The Mariners got their first series win since sweeping the New York Mets on Aug. 11, and the first of Dan Wilson's managerial career. They had fired longtime manager Scott Servais after a 1-8 road trip and badly needed a series victory.
''It was a big, big weekend for us,'' catcher Cal Raleigh said. ''We needed that, and I think the boys are pretty happy.''
Woo (6-2) allowed a two-run homer to Heliot Ramos in the first inning, but retired each of the next eight batters, and 12 of the next 13.
Woo allowed three singles over the next six innings, but didn't allow another runner to reach second base. He allowed two runs (one earned) on four hits, with no walks and seven strikeouts.
''Bryan Woo was tremendous today,'' Wilson said. ''The homer in the first inning, you know, I think when you try to get to good pitchers, you try to get to them early, and they were able to get him that one time early. But after that, wow. That was special.''
