EUGENE, Ore. – Freshman Cole Irvin gave No. 9 Oregon the start it needed and junior Tyler Baumgartner sparked the Ducks offense to a 6-1 win over San Francisco in an elimination game at the Eugene Regional Tournament on Sunday.

Oregon (47-15) advanced to the championship to play Rice on Sunday at 4 p.m.  The Ducks need to beat the Owls twice to advance to the NCAA Super Regional.

Irvin responded after giving up a leadoff home run allowing just five hits the rest of the way in pitching his fourth complete game of the season. The Ducks’ lefty set a new school record with his 12th win while fanning nine and walking none.

Baumgartner went 3-for-5 with two RBI and three runs scored, while Mitchell Tolman was 1-for-3 with two RBI and a run scored.

Justin Maffei gave San Francisco (35-24) an early lead with a leadoff home run in the bottom of the first inning off Oregon starter Irvin.

The Ducks tied the game in the third with an unearned run thanks to a couple fielding errors by Dons’ third baseman Bob Cruikshank. Baumgartner scored the tying run on a Tolman sacrifice fly after moving to third on a Cruikshank error on a hard-hit ball by Ryon Healy.

Shaun Chase gave the Ducks the lead in the fourth with a solo blast over the wall in left field. The home run was the third of the season for Chase and the first for a Duck hitter since Healy went yard May 4 at Washington State.

Baumgartner pushed the lead to 3-1 with a solo home run onto the roof of the Player Development Area over the right field wall in the top of the fifth. Baumgartner’s homer was his second of the season and his first at PK Park. He added another RBI in the top of the seventh on a double to right field that scored J.J. Altobelli and then scored on a ground out by Tolman to give the Ducks a 5-1 lead.

Ryan Hambright tacked on a run for Oregon with a RBI double in the top of the ninth.
