Kentucky's Kelsey Nunley pitched well enough to win on most days.
But Baylee Corbello pitched even better Sunday to lift LSU to a 2-0 softball victory at John Cropp Stadium.
The top-ranked Tigers thus avoided a three-game sweep. No. 15 Kentucky could take solace in having won the series.
Nunley, a junior right-hander from Soddy Daisy, Tenn., gave up two runs, one earned, on seven hits over 61⁄3 innings. She struck out nine and walked none.
Never miss a local story.
Corbello (8-0), a sophomore righty from Lake Charles, La., tossed a complete-game three-hitter. She struck out eight and walked two.
"I think, offensively, we didn't really put up the hits we needed to," UK Coach Rachel Lawson said. "I thought their pitcher, Corbello, did a nice job of keeping us off balance, and she hit tough pitches when she needed to. We had a couple opportunities to score but we didn't capitalize. I thought Kelsey did a great job.
"We had a few miscues defensively. That helped turned the lineup over too many times. But overall I was really impressed all weekend with our pitching staff and with our offense, and to come away with this series win says a lot about our program."
LSU (32-3, 6-3 Southeastern Conference) scored its runs in the fourth inning.
Kellsi Kloss led off with a single up the middle.
Sandra Simmons followed with a bunt single, and both runners moved up on a throwing error by third baseman Nikki Sagermann. UK would commit four errors in all.
Dylan Supak knocked in Kloss with a single to right-center.
One out later, Simmons scored when No. 9 hitter Emily Griggs singled through the left side.
Griggs had a career-high three of LSU's seven hits.
Otherwise, Nunley (10-5) baffled the Tigers.
"They're a really good team, so if I can hold a team like that to two runs, I think it's pretty good," Nunley said.
Asked if pressure of a pitching duel affected her, Nunley said "I try to let it not, but it does a little bit. I just try and focus on what my job is on the field."
UK (23-9, 3-6) had only two runners reach second.
Christian Stokes laced a two-out single in the third, advancing when Sylver Samuel reached on an error.
Corbello got Sagermann on a grounder to end the threat.
Samuel made it to second in the sixth inning, reaching on a one-out infield single and advancing on an error by Corbello.
Corbello got Sagermann on a popup and Griffin Joiner on a groundout.
Still, it was a good weekend for UK.
"It was awesome to be able to come out and get the series," Nunley said. "We needed that after the past two weekends we've had. So hopefully we're going to carry it over to Wednesday."
That is when UK will visit archrival Louisville.
"They've been having a good year. They've been winning a bunch of games," Lawson said. "They've done a nice job in the ACC. So hopefully it will be a good game. Hopefully things will go our way."
