OMAHA, Neb. — LSU committed two errors that led to UCLA’s only runs as the Bruins edged the Tigers 2-1 in the College World Series on Sunday night in TD Ameritrade Park.

Catcher Ty Ross’ throwing error set up the tying run in the sixth and shortstop Alex Bregman’s fielding error allowed the tiebreaking run to score in the eighth. Both runs were unearned and led to the first loss of the season for All-America right-hander Aaron Nola (12-1).

In three post-season starts covering 24 innings, Nola has not allowed an earned run. Sam Houston State scored five unearned runs against him and Nola shut out Oklahoma.

The Bruins (45-17) advanced to a winners bracket game against N.C. State, which defeated North Carolina 8-1 on Sunday afternoon, at 7 p.m. Tuesday

The Tigers (57-10), will play North Carolina in an elimination game at 2 p.m. Tuesday. The team that has won the most regular-season, Southeastern Conference and pre-CWS games in LSU history is suddenly starting at an 0-2 departure from the CWS if it loses Tuesday.
