"He's a very special player and I've coached him for years," said manager Kevin Gaines. "There's a lot of great kids here this week, but I wouldn't trade him for any of them."
With Mississippi leading 4-1 in the sixth and down to their final three outs, Tennessee rallied to tie the score at 4-all at the end of regulation.
Roundtree singled and knocked in Jacob Urmanski. Jacob Williams hit a fly ball to right that was dropped, allowing Eddie McDaniel to score with two outs.
Then Braxton McFarlin knocked in Roundtree to tie the game at 4-all forcing a 7th inning.
Mississippi scored once in the top of the seventh, but Roundtree pitched his way out of a bases-loaded jam.
"Our kids have really battled back and come from behind in every game,"said Gaines. "We're excited. There's six teams left and we're one of them."
