Boone, N.C. -- Georgia State scored nine runs in the last two innings, capped by Matt Rose's two-run homer in the ninth inning, to win 15-13 at Appalachian State, the fifth straight win for the Sun Belt Conference leaders. The Panthers improved to 13-3 in the Sun Belt, including 7-0 in conference road games.

Rose hit his Sun Belt-leading 12th homer of the season and drove in a career-high five runs on the day with a homer, two doubles and a single.

Georgia State (23-15, 13-3) trailed 12-6 in the eighth inning when Jack Thompson led off with a double, and then Justin Jones drove him in with a triple to the right field corner. After Caden Bailey walked, Rose ripped a double down the third base line to score two, bringing GSU within 12-9.

Joey Roach walked, and then with two outs, Sam Few delivered a run-scoring single and then Cam Sperry tied the game at 12-12 with a two-run double to left.

Apppalachian State (11-28, 4-16) regained the lead with a run in the bottom of the eighth on a pinch-hit double by Avery Jackson, leading to another Panthers' rally in the ninth.

With one out, Jones reached on a bloop double down the right field line. Trae Sweeting, who entered the game when Caden Bailey was ejected in the bottom of the eighth, laced a single up the middle to score Jones with the tying run.

That brought Rose to the plate, and he deposited the 1-0 pitch from left-hander Dallas DeVrieze over the left field fence for the 15-13 lead.

"He threw me a slider that caught a lot of the plate, and I just tried to put a good swing on it," Rose said. "The ball wasn't carrying well today so I knew I had to get a lot on it. I was just trying to hit a single to bring Joey (Roach) up, but thankfully it went out."

Frady added, "Matt Rose, once again, the most gigantic, clutch performer. Last night, Matt didn't have his best day, but today he made a really good adjustment. Not only was the home run big, but he hit all day long."

The Mountaineers mounted a threat in the bottom of the ninth as Noah Holmes and Drake Zupcic led off with back to back singles. But Jerry Stuckey (1-0) got Carson Jones to pop up and Brian Bauk to fly out before ending the game with by striking out pinch hitter Grayson Atwood looking.

Stuckey had come on in the eighth and struck out cleanup hitter Matt Brill with the bases loaded to end that inning. The senior right-hander earned his first victory of the season after saving Friday's win, which he also ended with a strikeout looking.

"We had a ton of things going on this game that made us want to win even more," Stuckey said. "We fell behind two different times, huge deficits, and we kept fighting back. I've got to thank the guys in the field for making great plays behind me."

After scoring three runs in the top of the first, Georgia State fell behind 7-3 after two innings. The Panthers mounted their first rally in the fifth inning, scoring three runs on a sacrifice fly by Sam Few, and run-scoring singles by Sperry and pinch hitter Jack Thompson to pull within 7-6.

But as GSU was rallying, senior second baseman David Levy became ill in the dugout and eventually had to be transported to the hospital for tests. Levy was later discharged and is expected to be fine.

Levy left the stadium during the bottom of the sixth as Appalachian State scored four runs to move ahead 11-6.

"It was a really trying time for us as a team, and it was hard to keep our focus," Frady said. "We all rallied together and dedicated the game to come back and win for him. We're all excited to see David back at the hotel."

"It was just an amazing game," he continued. "In my 28 years of coaching, this is one of my proudest moments, to see our team rally the way they did."

The Panthers, who won 4-3 in 12 innings on Friday, have now won six Sun Belt games in their final at bat.

The series finale is scheduled for Sunday at 1 p.m.
