The Rebels (2-0, 2-0) trailed 6-0 after three innings, but came back with four runs in the fifth and four in the seventh to steal the victory.
"For us, this was a big character builder," South coach Greg Eversole said. "It was a great comeback. This is a group of kids that lived in the shadows of last year's team. It was South High baseball. This team is just writing its own storyline."
Act one featured the Rebels' struggles. South pitchers allowed 10 Catoctin runners to reach first base via free passes - including four hit batsmen. Four of the gifts became Cougar runs.
Act two featured the Rebels' heroics. South used three errors to score four runs in the fifth. Two more errors and tired pitching helped South win the game in the seventh.
Leadoff hitter Frankie Linton drew a walk against Rusty Wood to open the seventh. Jeremy Favorite replaced Wood and was victimized by a double error on Brian Glines' grounder. Walks to Dustin French and Brad Taylor produced a run.
Corey Krietz relieved Favorite and was greeted by Donnie Wright's RBI single. Carbaugh then ended the game with his two-strike single up the middle.
"I had struck out the last two times up and I was worried I was going to do it again," Carbaugh said. "If (Krietz) had thrown it outside, I'd have whiffed. But he put it down the middle and I stuck it."
Carbaugh's hit erased South's early pitching woes. Starter Daryl Keadle struggled, hitting Catoctin's Pat Sherald with his first pitch. Keadle then gave up a two-run homer to Dane Miller, which highlighted a three-run first. Catoctin chased Keadle with two runs in the second, leaving the game up to Linton and winner Zach Swisher.
Wright led South with two hits. Jason Jenkins had three hits for Catoctin (1-1, 1-1).
"We just ran out of arms and we kicked the ball around a little defensively," Catoctin coach Tom Sherald said. "We ran ourselves out of a couple of innings with runs we needed in the end. You can't score enough runs against South."
