The Ceres Sizzle eight-and-under travel softball team had a breakthrough performance when it placed first at the Hilmar tournament on July 7.
The Sizzle won their second straight title this past weekend, finishing 6-0 at its home event.
Ceres totaled 58 runs.
"Winning at home was emotional and exciting for everybody," head coach Misty Roton said. "It's by far the best we've played all year. Our defense was 100 percent on. We were hitting so well."
The Sizzle exacted revenge, beating the Modesto Fusion 8-1 for the title on Sunday at George Costa Ball Field Complex.
Modesto edged Ceres 5-4 in the championship game of the Newman tournament earlier this summer.
"We redeemed ourselves," Roton said. "The girls stepped up."
The Sizzle held a slim 2-1 lead through four innings during the rematch.
Ceres broke the game open with a five-run outburst in the fifth inning.
The Sizzle won their semifinal matchup versus Hilmar, 8-4, on Sunday.
Ceres defeated Hilmar (11-1), Newman (12-0) and Atwater (13-3) by the four-inning mercy rule on Saturday.
"We were unstoppable," Roton said. "We expected them to do well. We didn't expect them to be this good."
The Sizzle improved to 19-2 on the season.
Ceres might sign up to play in a tournament in Brentwood the weekend of July 27-28.
"I don't think any of these girls will forget this summer," Roton said. "They made friends and had amazing games."
