Alabama (29-12, 11-6 SEC, 1st SEC West) goes for the series sweep Sunday at 2 p.m. against the Gamecocks (29-11, 9-8 SEC).
LeBlanc made his SEC return a week ago against Florida, but was for 10 hits in four and one third innings in the loss.
Saturday, LeBlanc gave up four runs, allowing five hits and one walk. He recorded just three strikeouts, and recorded 19 outs on fly balls or pop-ups.
"LeBlanc pitched better, but not at full strength," Alabama Head Coach Jim Wells said. "It's good when a guy's been out five weeks, has had two so-so starts, and can come out and go nine innings."
With the one-two punch of Gabe Scott and Evan Bush struggling to a combined 1-for-8 at the plate, Alabama found its offense elsewhere, and was able to score 10 runs in the fourth through seventh innings.
It was the three batters who follow Scott and Bush in the lineup providing most of the run-support. Morrow Thomley, Zac Welch and Kody Valverde, hitting fifth, sixth and seventh respectively, each had a home run and two RBI Saturday.
Thomley was 3-for-4 on the day with two stolen bases, while Welch and Valverde were each 1-for-3.
The game was in hand for Alabama, but Scott's 27-game hitting streak was on the line when he came to the plate in the ninth inning for his fifth plate appearance, but the Lake Charles, La. senior grounded sharply into a 6-4-3 double play, ending the streak.
The end of Scott's streak was acknowledge by a standing ovation from the 4,452 in attendance.
"It's nice that people appreciate him. He literally carried us through some games and the others had to pick him up today," Wells said.
South Carolina took a first-inning 1-0 lead when Steven Pearce wanded a two-out pitch over the left field wall.
"We get down early every game," Wells said.
South Carolina ran out to a 3-0 in the fourth inning with another two-out hit. Pearce singled and DH Jon Willard walked to set up sixth-place hitter Chris Brown. Brown hit a gapper that bounced to the wall in right center field, scoring Pearce and Willard.
Alabama matched that with two runs in the bottom of the fourth. Thomley's one-out blast to left field brought in Scott, who had walked to lead off the inning.
LeBlanc, after allowing the two-run double in the fourth, retired the next 14 batters, and 16 of the final 17 batters faced.
"Towards the end I started to locate everything better and just let them get themselves out," LeBlanc said. "It's obvious that I got a lot better from last week to this week and I'll pick up more as I get more innings under my belt."
Meanwhile Alabama posted one run in the fifth inning, five runs in the sixth inning and two runs in the seventh inning.
Bama manufactured a fifth-inning run when Allen Rice, with runners on first and third, hit a sacrifice fly to score Cale Iorg. Iorg had led off the inning being hit by a pitch.
Iorg advanced to second in the frame on a sacrifice bunt by Greg Paiml, but Paiml reached on the play when the pitcher elected to throw to second, too late to retire Iorg.
Runners were left on the corners after Emeel Salem hit into a fielder's choice that put Paiml out at second.
Bama sent Gamecock starter Jason Fletcher from the game in the sixth after Welch's two-run shot to center field with Morrow Thomley on second.
South Carolina went to Jeff Jeffords, who walked two batters, gave up a single and threw two wild pitches while failing to record an out.
Allen Rice faced Wynn Pelzer, the third S.C. pitcher of the sixth inning, and hit a deep ball to center field that grazed off the glove of Davy Gregg for a three-base, three-run error that extended Alabama's lead to 8-3.
Valverde's homer came in the seventh off Andy Lambert with a man on base to cap the Tide scoring.
Pearce hit a one-out solo shot in the ninth to bring the score to 10-4, but LeBlanc retired the next to batters to close out the complete game.
"I always expect to go nine (innings), so I wasn't surprise. I want to take that upon myself to save our bullpen," LeBlanc said. "It's a big help for Sunday. T.J. was able to go eight last night and I was able to go nine today."
Wells said Bama's Sunday starter has not been determined, but the Tide will likely throw some combination of Jordan Davis, Brent Carter and David Robertson.
