BATON ROUGE, La. — South Carolina freshman pitcher Jack Wynkoop hurled seven scoreless innings and combined with Adam Westmoreland and Tyler Webb for a six-hit shutout as the 10th-ranked Gamecocks defeated No. 2 LSU, 4-0, on Sunday afternoon to win the rubber game of a three-game Southeastern Conference series at Alex Box Stadium.

While winning the series, 2-1, the Gamecocks, which next host Vanderbilt on Friday at 7 p.m. (SportSouth), improved to 33-12 and 13-8 in the SEC while LSU dropped to 39-6 and 16-5.

Wynkoop (6-2) scattered five hits with no walks while striking out a batter. Westmoreland hurled 2/3 of a scoreless inning and Webb had 1 1/3 perfect innings of relief for his 14th save of the season.

South Carolina collected seven hits with LB Dantzler and Max Schrock each getting two.

The Gamecocks struck right away with two runs in the top of the first inning. Chase Vergason tripled with one out as he hit a liner that flew past a diving Jared Foster in right field. With two outs, Vergason would score on LB Dantzler’s RBI double down the right field line. Schrock would then drive in Dantzler with a RBI single to right field giving Carolina a 2-0 lead.

The lead increased to 3-0 in the top of the second. Tanner English drew a leadoff walk and advanced to third on a base hit to left off the bat of Graham Saiko. Vergason would drive in English with a sacrifice fly to right field.

LSU looked to mount a rally in the eighth with a one-out single by Mark Laird and a two-out walk to Jared Foster. Webb entered though and coaxed Alex Bregman into a flyout to right field to keep Carolina ahead by three runs.

USC scored an important insurance run in the ninth inning as Sean Sullivan reached base with a leadoff walk. After a sacrifice bunt by Tanner English was misplayed by Katz to give Carolina a pair of runners, both moved into scoring position on Saiko’s sacrifice bunt. Sullivan would score on Vergason’s sacrifice fly to right field, his second of the game. Webb worked a perfect ninth to seal the 4-0 victory.
