PORTLAND — In a setup featuring a pair of Southern Oregon's finest, former South Medford High standout John Adamson came out on top Saturday night for the first-year Oregon baseball team.

Pinch-hitting with one out in the 10th inning, Adamson stroked a line-drive double to right field off former Ashland High ace Sam Gaviglio, scoring Caleb Tommasini with the winning run as Oregon rallied for a 3-2 victory over Oregon State.

The game was played before a Pac-10 regular-season record 15,540 fans at PGE Park. The rubber match of the three-game Civil War series will be played at 1 p.m. today at PGE Park.

The Beavers led 2-0 through 71/3 innings, but the Ducks sent the game to extra innings after scoring twice in the eighth on just one base hit.

After a scoreless ninth — with Gaviglio sitting the Ducks down in order — and top half of the 10th, Tommasini started the bottom of the inning with a walk and was sacrificed to second.

Adamson then bounced a double to right field to score Tommasini and allow Oregon (11-13) to even its Pac-10 record at 1-1.

Oregon's baseball program had been dormant from 1981 until this season. Oregon State (14-6), which recently won back-to-back national championships, is also 1-1 in league play.

Oregon State won the series opener 7-1 in Eugene on Friday and Beaver fans wanted more fireworks.

But after an hour-long rain delay at the start, the game became a pitchers' duel.

Oregon starter Erik Stavert cruised through the first six innings, giving up just three hits, before Oregon State got its first run in the seventh after a single by Stephen Romero, a walk by Michael Miller and a two-out single by John Wallace.

The Beavers struck again in the eighth when Romero tagged Oregon reliever Madison Boer for a two-out double that scored Ryan Ortiz for a 2-0 lead.

On the other side, the Ducks squandered several opportunities in the middle innings.

In the third they loaded the bases but couldn't score, and had two runners on with one out but stranded both in the fourth.

One inning later, the Ducks had runners on first and third but the inning ended when Tommasini was caught in a rundown at third.

Oregon finally broke through in the bottom of the eighth, scoring twice with just one base hit after Danny Pulfer and Tommasini were plated by walks.
