Hillson drove in the Tigers second run after being hit by a pitch and Sam Rotella added an RBI on a single to left, however, Behrent helped snuff out the rally when on the play he threw out Whitmyer to end the inning.
Southern scratched out a run in the bottom of the second when Young and Garrett Sosnoski singled with one out and Blake Marks' grounder to second was misplayed allowing one run to cross the plate.
The Tigers lead grew to 8-3 in the third when Hunter reached on an error and Zigarski legged out a triple to center. Hillson put down the next two batters before Young singled to left for the game's final run.
"Southern really hit the ball well and none of their hitters got cheated at the plate," Perry said. "They are very aggressive offensively and have good batters up and down the lineup."
Klock, after his shaky second, settled down the rest of the way and allowed just a meaningless single in the fifth while finishing the game with five strikeouts. His defense also turned in a double play in the fourth and did not commit an error.
"Klock pitched a very effective game and nothing was really hit hard off him," Young said. "He gave us a complete game and we have the rest of the pitching staff ready for our game against East Juniata."
Sosnoski led the winners with three singles while Peters and Behrent each contributed a home run. Zigarski chipped in with a triple and Marks added a double.
Hillson, Rotella, Colsgrove, Whitmyer and Andrews each had a single for the losing Tigers, who ended their season with an 11-8 record.
