UTSA earned the Western Athletic Conference's automatic bid with Sunday's 11-4 victory over Dallas Baptist. Oregon State beat UTSA in the only meeting between the two squads but it was a tough win, 10-7, in 10 innings back on Feb. 28, 2011.
Texas A&M (32-27) went 13-16 to finish sixth in the Southeastern Conference's West Division. UC Santa Barbara (34-23) won their final six series of the season and finished second in the Big West with a 17-10 conference mark.

The Beavers are hosting an NCAA Regional for the fourth time in school history, and have gone a combined 9-0 in 2005, 2006 and 2011.
With one of the eight national seeds, the Beavs are guaranteed to host a super regional if they advance this weekend in the regional.
The winner of the Corvallis Regional will move on to face the winner of the Manhattan Regional, which includes host Kansas State (41-17) as well as Arkansas (37-20), Bryant (44-16-1) and Wichita State (39-26).
Regional play in the NCAA baseball postseason is double elimination. The 16 winners move on to the Super Regional, which is best 2-of-3. The 8 winners move on to the College World Series in Omaha, which is double elimination until the championship series, which is best 2-of-3.
The eight national seeds:
1. North Carolina
3. Oregon State
5. Cal State Fullerton
7. Florida State
"I know we've talked Vanderbilt, LSU and North Carolina as being really complete (teams), watch out for Oregon State. This is a club that has a really legitimate chance to win the whole thing," said ESPN analyst Kyle Peterson.
But another ESPN analyst, Ben McDonald, thought it would be a "huge surprise" if the champion didn't come from the SEC/ACC and that LSU, Vanderbilt and North Carolina had separated themselves as the top three teams.
The Pac-12 received four bids - Oregon State, Oregon, UCLA and ASU.
