Heritage won its third region championship in six years on Saturday, under head coach Steve Chattin.
The Lady Generals, which qualified for the state tournament earlier in the week, scored three runs in the bottom of the eighth inning to edge host Northwest Whitfield, 8-7.
Lauren Lawson (22-4) recorded the win by recording eight strike outs.
,Lawson has now set a new school record with 47 career pitching wins.
Chattin said he was thrilled his team was able to pull the victory out against a squad the Generals have faced nine times in two years.
"It always feels good to set goals and accomplish them," he said. "One of your goals in to the season is to win a championship ... even though it's our third time to win it, it's the first time for some of these kids.
Chattin said defeating Northwest Whitfield, again, was bittersweet.
"Ever since they realigned the region, we're one of the top teams in the region and have had quite a rivalry. They're a good solid program."
Chattin said his Generals were confident, but not overly confident heading into this week's first round of state playoffs with Carrollton on Wednesday.
"We're aware Carrollton has a very good ball club," he said. "They have a pitcher that has thrown very well and they have six seniors. She's also thrown two no hitters."
Ali Roberts had three hits in the championship game. That included one sacrifice fly, one run scored and an RBI.
Olivia Tamewitz had three hits and one run scored.
Sydney Smith had two hits, including a double and Hannah Wills, Shelby Hammontree, Katie Pritchett, Brooklynn Frazier and Krissi Prewitt and Shea Headrick all had one hit each.
