Kentucky's baseball team, ranked No. 1 by Collegiate Baseball and No. 2 by Baseball America, gave up five runs in the eighth inning to lose 6-1 to Vanderbilt on Sunday afternoon in Nashville.
Four of the runs came on a grand slam by the Commodores' Connor Harrell. The teams split the first two games of the weekend, so the loss meant that Kentucky (36-9, 14-7 Southeastern Conference) had lost its first series this season.
UK, which had won its first six SEC series and started this one with a 5-2 victory on Friday night, managed only five hits on Sunday. Luke Maile had two of those, and Thomas McCarthy, Zac Zellers and Matt Reida had one apiece.
UK starter Corey Littrell worked 51⁄3 innings, allowing six hits and walking two with four strikeouts.
