ATLANTA -- Jordan Lee pitched 7-1/3 strong innings and Jack Thompson drove in the go-ahead run with a seventh-inning double to give Georgia State a 3-2 win and a three-game sweep of Sun Belt Conference foe Arkansas State Sunday at the GSU Baseball Complex.

The Panthers (16-15, 5-6 Sun Belt) swept a three-game Sun Belt series for the first time since 2015.

Lee, the senior right-hander, pitched into the eighth inning in a career-long outing to improve to 3-0 on the season. He allowed just two runs, both in the third inning, on three hits with four walks and a career-best seven strikeouts.

“My defense was huge for me today,” Lee said. “My slider and my changeup were really effective today, but I can’t emphasize enough how well my defense played behind me.”

In a 2-2 tie, Justin Jones led off the seventh inning with a walk and moved into scoring position on a wild pitch. After a pair of flyouts, he was still at second base with two outs when Thompson, the Panthers' senior first baseman, smacked a double off the wall in right field, scoring Jones with the go-ahead run. Will Kilgore followed with a single through the left side, but Thompson was thrown out at the plate to end the inning.

"Jack Thompson had a huge RBI, but Justin Jones able to get on base and then moving up on a ball in the dirt was the difference, and we won a tight ballgame," head coach Greg Frady said.

Lee came out for the eighth, and after walking the leadoff hitter, he got the first out on a fly ball. With Arkansas State's (11-16, 3-9) best hitter, left-handed hitting first baseman Kyle MacDonald, coming to the plate, the Panthers turned to left-hander Brandon Baker, who struck out MacDonald for the second out.

Then righty Bryan White came on. He issued a walk and threw a wild pitch to put runners at first and third, but the senior got a fly ball to end the inning.

Arkansas State put the tying and go-ahead runs on again in the ninth, but White ended the game with a pair of strikeouts to earn his first save.

"Today we won a game differently than the first two games in the series," Frady said. "Today was really about pitching and defense and then getting a timely hit.

"Jordan Lee was amazing today in how well he pitched and how long he pitched. I'm so happy for him. Secondly, for the second time this weekend, Brandon Baker came in in a pivotal moment and got a big out for us. And a great job by Bryan White to finish the game."

And Frady also credited the man behind the plate for those three pitchers.

"There's a lot of professional interest in Nick Gatewood, especially as a hitter," Frady said. "Today, he showed why he is one of the great catchers in our league and in college baseball. The way he blocked a ball with a runner at third. He even got crossed up and was able to handle the pitch. Nick was absolutely amazing as a catcher today."

Georgia State started the scoring with a pair of runs in the second. After Luke Leonard walked, Romero Greer singled and Kalen Puckett walked to load the bases with one out, Jones delivered an RBI-single for the first run. Gatewood followed with an sacrifice fly for a 2-0 lead.

But the Red Wolves answered with a two-out rally in the third. Grant Hawkins walked and stole second, and MacDonald drove him with a single and then scored on Jeremy Brown's double down the left field line to tie the game at 2-all.

Gatewood singled in the fourth inning to extend his hitting streak to 14 games.

"I'm overjoyed and excited about sweeping Arkansas State. It's hard to sweep any team," Frady said.

Georgia State takes its three-game winning streak into a Wednesday game at Georgia Tech at 6 p.m. at Russ Chandler Stadium.
