Jackie Bradley and Adrian Morales homered during an eight-run second inning that propelled South Carolina to an 11-4 victory over No. 1 national seed Arizona State on Tuesday, knocking the Sun Devils out of the College World Series.
The Gamecocks (49-16) advance to Thursday's game against the loser of Tuesday night's Clemson-Oklahoma game. Thursday's game will be at 7 p.m. ET and televised on ESPN2.
Winning pitcher Sam Dyson (6-5) threw 7.1 innings, struck out three and allowed four earned runs.
"It's a lot easier when you have eight runs on the board," Dyson said. "It's a good weight off your back when they put up that many runs."
Never miss a local story.
Head coach Ray Tanner praised the pitching and defensive effort in both of South Carolina's CWS games.
"We only allowed four runs two games in a row," Tanner said. "That eight-run inning propelled us to a good position."
Tanner said he hasn't figured out the pitching plan for Thursday's game. He said Blake Cooper should be available either in a starting or relief role.
South Carolina eliminated Arizona State after the Sun Devils twice sent the Gamecocks home from Omaha (in 1981 and 1977).
Arizona State suffered a Palmetto State knockout in this year's College World Series, falling to Clemson and South Carolina. The Sun Devils finish the season 53-10.
With Arizona State gone, the 1999 Miami Hurricanes remain the only No. 1 national seed to have won the championship since the tournament expanded to 64 teams that same year.
Dyson was relieved by Matt Price after allowing two runs in the eighth.
Price struggled at first, giving up two singles and hitting a batter to load the bases, but he caught Austin Barnes looking at strike three and then struck out Drew Maggi after running the count to 3-0.
Whit Merrifield finished a 3-for-5 game with his 13th homer to give the Gamecocks a seven-run lead.
The eight-run second was Arizona State's worst inning in 196 games, since giving up nine in a 14-5 loss to Arizona on May 25, 2007.
All eight were charged to Merrill Kelly (10-3), who was pulled after Morales homered off the left-field foul pole.
Kelly, the Tampa Bay Rays' eighth-round draft pick, was tagged for 10 hits in 1 2-3 innings in the second straight disappointing performance by an ASU starting pitcher. Previously unbeaten ace Seth Blair walked four of the first 12 batters he faced and gave up five runs and seven hits in 4 1-3 innings in Monday's 6-3 loss to Clemson.
Five of South Carolina's first six batters reached base in the second inning before Bradley launched a three-run shot into the bleachers in left center for his 13th homer, and Morales finished the barrage with a two-run homer, his ninth.
The eight hits in the second were most in an inning by the Gamecocks this season.
The Gamecocks added two runs in the third when Mitchell Lambson hit a batter and walked another with the bases loaded.
Bradley, who went 3 for 4 and extended his hitting streak to 18 games, matched his career high with four RBIs.
ASU's Riccio Torrez had his 26-game hitting streak end. He was hit by pitches twice, struck out twice and flied out.
The game was delayed seven minutes in the middle of the seventh inning after home-plate umpire David Savage left to be treated for heat-related symptoms. Second-base umpire Kelly Gonzales took over behind the plate.
