EUGENE, Ore. – Drew Maggi’s first career home run was the only thing No. 1 Arizona State needed to remain undefeated with a 1-0 victory over Oregon on Thursday night at PK Park.

In front of 2,114 fans, Oregon left-hander Tyler Anderson (4-3) threw the first complete game of his career and held the No. 1 Sun Devils (24-0, 4-0) to one run on four hits. The left-hander fanned 10 – one short of his season high – but one pitch in the top of third proved to the difference maker in the series opener.

With one out on the scoreboard, Maggi took Anderson’s 1-1 offering over the wall in left field to give ASU a one-run lead that would prove to be the difference in the game for the final seven innings.

Arizona State starter Seth Blair improved to 5-0, tossing seven shutout innings and striking out five. Mitchell Lambson and Jordan Swaggerty each pitched an inning of relief for the Sun Devils. Swaggerty struck Jett Hart – who was pinch hitting – in the bottom of the ninth bringing the go ahead run to the plate, but ASU’s top closer retired UO’s final three batters to retire the side and pick up his eighth save of the season.

Hart made his way to second on Jack Marder’s sacrifice bunt in the ninth, but Shawn Peterson struck out and J.J. Altobelli grounded out to Maggi at shortstop to end the game.

Oregon (18-9, 1-3) had its best opportunity to put runs on the board in the seventh as Peterson - the tying run -was just 90 feet away at third. He was hit by Blair and took first with two outs on the scoreboard, and moved to third on Altobelli’s single to right center.

But Blair caught Curtis Raulinaitis looking at strike three for the final out of his seven innings on the mound.

In addition to a more-than impressive performance by Anderson on the hill, Oregon’s defense played well with highlight reel plays from shortstop KC Serna, right fielder Steven Packard – who picked up his third assist from the out field – and Altobelli at third.

Oregon’s series with Arizona State resumes on Friday with first pitch scheduled from PK Park at 7:03 p.m.

Oregon is hosting “Joe Gordon Day” at PK Park to honor the program’s first National Baseball Hall of Famer. In attendance will be Gordon’s family and friends, including his daughter Judy, who will throw out the first pitch. Hall of Famer Bobby Doerr - a former major leaguer with the Boston Red Sox - will also be in attendance along with his son, former Oregon pitcher Don Doerr.

Notes: Oregon's 1-0 loss marked the first time the Ducks have been shut out this season, and thie first time since a 2-0 loss at Oregon State on March 19, 2009...this is the first nine-inning complete game thrown by an Oregon pitcher since Erik Stavert threw nine innings in a loss to Washington on April 25, 2009...UO last played the No. 1 team in the country, taking on top-ranked UC Irvine April 20-21, 2009 in Irvine, Calif.
