BATON ROUGE, La. —the Auburn Tigers scuffled for runs Saturday against LSU freshman pitcher Eric Walker, but hits proved to be elusive. But LSU’s hitters solved Auburn right-handed Casey Mize unlike any opponent has all season and chased him after four innings. That combination resulted in an LSU series sweep with a 9-1 win. Auburn’s losing streak is at seven games, the program’s longest since 2006. LSU’s No. 3 starter did not permit a hit until nine-hole hitter Sam Gillikin hit an opposite-field home run — his first of the season. That was one of only two hits for Auburn, which scored just four runs (two earned) in 27 innings against the dominant performance of LSU starters Alex Lange, Jared Poche and Walker. Auburn heads home to close out the regular season with a series against Ole Miss, which starts at 6 p.m. Thursday.
