TEMPE, Ariz. – Arizona State right-hander Kramer Champlin was very effective and Mitchell Lambson closed the game out for the second night in a row as the fifth-ranked Sun Devils clinched the series with a 3-1 victory over Oregon on Saturday night at Packard Stadium.

Arizona State (20-6, 4-1) won its second Pac-10 series of the year with the win over the Ducks, while Oregon (14-11, 0-2) has now lost its conference-opening series in 2011. The Ducks and Sun Devils will play the series finale with first pitch set for 12 p.m. on Sunday from Packard Stadium.

Champlin (4-1) tossed eight innings of one-run baseball, holding the Ducks to five hits of which four were for extra bases. In addition, Champlin struck out seven and walked none.

Champlin retired 10 consecutive batters until Danny Pulfer drove a one-out double down the left field line in the top of the fourth – extending his hit streak to 10 games. Champlin faced just four batters over the minimum in his eight innings of work.

Lambson came on in the top of the ninth and earned his fourth save of the season, retiring the side despite giving up a bunt single to freshman Aaron Jones .

Oregon junior right-hander Madison Boer (2-1) had a respectable performance on the mound, allowing three runs on nine hits in six and 2/3 innings while striking out six and issuing just one walk. For Boer it was his sixth quality start of the season and his first loss of the year as Oregon’s offense couldn’t support his outing.

Arizona State took a 2-0 lead in the bottom of the third as Andrew Aplin’s one-out double did damage. Zack MacPhee then drove a two-out RBI double up the middle that KC Serna tried to reach. The ball deflected into right field off Serna’s glove, turning a single into a double as Aplin scored.

With MacPhee sitting at second, Riccio Torrez’s RBI single took a hard bounce under the glove of Serna moving into center and allowing MacPhee to score the Sun Devils’ second run.

Oregon cut the Sun Devils 2-0 lead in half in the top of the seventh as Aaron Jones led off the inning with a double down the left field line. He was moved to third on a groundout and scored on Shawn Peterson ’s sacrifice fly to right.

But Aplin’s solo home run to right in the bottom of the seventh built ASU’s lead to 3-1. It was Aplin’s first round-tripper of the season and the first Boer had surrendered this year.

After surrendering a single to Johnny Ruettiger, Boer’s night was over and freshman left-hander Porter Clayton was brought on in relief.

Serna laced a two-out double down the right field line in the eighth, but was thrown out trying to stretch it into a triple – denying Pulfer the chance to hit.

Scott McGough finished the game for Oregon tossing one and 1/3 shutout innings.

Pulfer led the Ducks with a 2-for-4 performance that included both hits as doubles. Jones was 2-for-4 for UO with a run scored.

Ruettiger, MacPhee, Aplin and Matt Newman each had two hits for ASU.

The third game of tomorrow’s series is set for a 12 p.m. start from Packard Stadium.
