Clemson coach Jack Leggett said Schmidt (1-2) was pitching well and did not want to take him out. "They just got to him a little bit and unfortunately for us, they pieced together some hits," he said.
Slaton said his throw on Mooney's hit was a bit up the third base line, but it looked like Okey had made the play. But he said it will be important for the Tigers not to let what happened this weekend cloud the rest of their season.
"This is a tough one to swallow," he said. "We could've very easily gotten two (wins) out of this weekend. But we didn't and now we've just got move on."
For much of the game, it looked like Clemson's Long and South Carolina's Wil Crowe would dominate this one on the mound.
Crowe, who hadn't given up a run his first two college starts, matched Long's performance nearly pitch for pitch and the game was tied at 1-all heading into the sixth. Clemson picked up runs in the sixth on Okey's double-play ball and in the seventh on Slaton's RBI single to post Schmidt with a 3-1 lead.
Schmidt was on fire until midway through the ninth. He induced an inning-ending double play in the seventh to end a Gamecocks threat, then struck out four of the next six batters he faced before South Carolina's rally.
Kyle Martin got things started with a one-out single before Greiner started a string of two-out hits by Celek, Mooney and English.
"This is amazing," said Mooney, whose brother Peter was a shortstop on South Carolina's 2011 national championship squad. "I wasn't expecting that much, but this is exciting."
