Beggs (8-1) struck out seven and walked only one in a dominant performance against the Gamecocks. Only two runners reached scoring position against the UK senior right-hander, who tossed his second complete game of the season and lowered his ERA to 2.50.
He also became the first UK pitcher to shut out a ranked opponent since Alex Meyer blanked top-ranked Vanderbilt on May 6, 2011, at Cliff Hagan Stadium.
Luke Becker had two hits, Tristan Pompey homered and Kole Cottam drove in two runs to lead the Wildcats (28-19, 12-11 SEC) at the plate. Dorian Hairston also drove in a run for UK.
Kentucky jumped on South Carolina starter Braden Webb (6-2) early, plating three runs in the second inning. The talented freshman right-hander allowed five runs on six hits and two walks over seven innings despite a 10-strikeout effort. He entered the game leading the SEC in strikeouts.
Alex Destino had two of the three hits for South Carolina (36-10, 16-6 SEC), including a double.
The series concludes at 3 p.m. ET on Sunday at Cliff Hagan Stadium. The game will be broadcast on EPSNU.
