The Eagles won the first game 6-2. Lucas (6-1) scattered four hits to earn the win. Bill Henke recorded the final three outs in the seventh to claim his ninth save of the season. Morehead's Tyler Bess gave up only four hits, but got tagged with the loss.
"The second game was a great pitchers duel," JSU coach Jim Case said. "I thought it was really good that Austin kept throwing up zeros on the scoreboard, even when the game got tight, and I thought that was the difference."
Another key was Kyle Bluestein taking a couple for the team. The Gamecocks (27-16, 10-7 OVC) grabbed a 1-0 lead in the second after Bluestein was hit by a pitch, moved to third on a pair of ground balls, then scored on the second Morehead error of the inning.
Bluestein got hit again in the sixth, then Adamson followed with his team-leading 10th homer of the season.
"I find it interesting that two of the biggest things that turned the game around was a hit batsman," Case said. "Bluestein got hit twice in the game and scored on both of them. It's just funny how the little things can turn into big things."
The Gamecocks never led in the opener. They fell behind 1-0, then tied it on Steven Leach's sacrifice fly. The Eagles (16-26, 9-10) went back ahead 3-1, but the Gamecocks could only get as close as 3-2 on Bluestein's sacrifice fly in the sixth.
JSU leftfielder Todd Cunningham extended his hitting streak to 18 games in the opener, but went hitless in the nightcap.
The split dropped the Gamecocks into a virtual tie for third place with Murray State in the OVC standings, but the Racers hold the place by percentage points. They are one game behind second-place Southeast Missouri for the second first-round tournament bye.
Junior ace Ben Tootle is scheduled to start today for the Gamecocks.
