LSU's Aaron Nola pitched seven innings, giving up one run on four hits, to improve to 5-0 on the season in the No. 2 Tigers' 11-1 victory against No. 9 Kentucky at Baton Rouge, La., on Friday night.
The Cats' only run came on Austin Cousino's RBI single in the fifth inning that scored Matt Reida and tied the game 1-1.
LSU exploded for four runs in the fifth with an RBI single from Christian Ibarra and a two-run single from second baseman JaCoby Jones, putting the Tigers ahead for good.
Outfielder Raph Rhymes and first baseman Mason Katz added insurance runs in the sixth with RBI hits of their own, increasing the Tigers lead to 8-1.
Jones had a team-high three hits and two RBI for LSU.
"The final score is a little misleading, because this was a very competitive ball game for most of the night," LSU Coach Paul Mainieri said. Kentucky has an excellent ball club, and Ill allow our players to celebrate this one for about an hour before we turn the page and focus on the next game.
Kentucky fell to 22-7 overall and 6-4 in the Southeastern Conference.
With the win, LSU (28-2, 9-1 SEC) matched the best start in school history, previously achieved in 1986.
The teams play the second game of their three-game series Saturday at 7:30 p.m.
