Winners of their last five games, the Oregon baseball team concludes the regular season at home against California beginning tonight. For the Ducks (41-16, 17-10 Pac-12), the series may look fairly meaningless on paper, as they’ve all but locked up a postseason berth. However, a sweep would put them in position to host a regional.

“If we’re worthy of a sweep of Cal, come in third in the (Pac-12), it might make it difficult for (the selection committee) to not give us a top 16, or essentially a site,” Oregon coach George Horton said following Oregon’s win over Oregon State Tuesday night.

“There’s a lot on the line,” Mitchell Tolman said. “Obviously we can’t think sweep right now. We have to think (about) the Thursday game, just come out and win one day at a time. But this is a big weekend either way you look at it and we gotta do what we can do.”

The Golden Bears are led offensively by Devon Rodriguez, who leads the team in hits (52), RBI’s (34) and is tied for the team lead in homers (7). As a team, Cal hits for a .239 average, second to last in the conference.

Probable starting pitchers for game 1 are Tommy Thorpe (9-4, 2.33 ERA) and Daulton Jeffries (2-7, 3.34 ERA). Jeffries’ record doesn’t reflect it, but he’s been a reliable arm for Cal this season, especially in conference play. In nine Pac-12 starts, Jeffries has an ERA of 3.17 and a strikeout to walk ratio of nearly three to one.

Oregon will continue to ride the conference’s most potent offense. The Ducks have scored the most runs among Pac-12 teams this season (327) and have the top home run hitter in Shaun Chase. Chase hit two  more homers Tuesday to up his season total to 12. Chase’s 12 long balls are the most an Oregon player has hit in a season since the program’s reinstatement in 2009, and tied for the third most in program history, trailing only Steve Crum (1981) and Jim Willis (1974), who both hit 14.
