It took Boonsboro time to find the offense against first-time South starter Chris Harman. The Warriors squandered opportunities but still managed to hold a 2-0 lead after three innings.
The Warriors (4-5) broke loose for three runs on six hits in the fourth inning, which South could have avoided without the throwing error that opened the floodgates. It set the table for RBI singles by Hershberger, Rodney Flora and Snavely.
Jordan Hatfield started the fifth for South and walked three to allow Boonsboro to make it 8-1 with an RBI single by Scott Haupt and a two-run single by Snavely.
The Rebels (3-6) closed the gap to 8-4 with a pair of runs in the fifth inning on Tyeler Presgraves double. Adrian Adams added a solo homer in the sixth.
Snavely keyed a three-run sixth with a two-run triple before scoring on Poffenberger's third hit.
South scratched away against Boonsboro reliever Chase Woods with the help of two Warriors errors. The Rebels also drew a pair of walks and advanced on a balk before Woods shut the door.
Poffenberger went into the sixth inning on 90 pitches, using 40 in a nifty first three innings, while allowing only two hits.
Rebels coach Ralph Stottlemyer started Harman, hoping to get four innings from the right-hander.
"Harman did fine," said Stottlemyer. "We just have to catch the ball and make plays behind him."
Jordan Hatfield also got a look, pitching two innings but got into trouble with four walks.
"We're just not in sync right now," said Stottlemyer. "(Four) errors hurt us again, and we're still looking for clutch hitting."
The Rebels had 11 hits and received five walks but stranded 11 runners.
Presgraves, Adams, Cory Shank and Dwight Boward had two hits apiece for South.
