The Dons (27-0, 14-0 in league) made a pair of first-inning runs hold up, backed by strong defense and another stellar outing from senior pitcher Johanna Grauer, who gave up just two runs and threw one no-hitter during the CIF North Coast Section Division I championship tournament.
"We've had many tight games this year, and it's only fitting that the championship game would take this shape," Amador coach Teresa Borchard said. "In the end, it's the combination of hard work, athleticism and mental toughness that produces a perfect season like this one."
Grauer's two-out double got the Dons offense going in the bottom of the first inning. Shortstop Ashley Lotoszynski drove in Grauer with a triple, and catcher Victoria Molina followed with an RBI single to plate Amador's second run.
That proved to be all the scoring Grauer and the top-seeded Dons would need against the No. 3 seed from Livermore.
Grauer scattered five hits and struck out 11 Granada batters during the complete-game effort.
The Matadors' only run was a solo home run by Taylor Zehr in the top of the sixth inning. The deep ball followed a 10-minute delay after Zehr hit her head in the dugout just before her at-bat, Borchard said.
Infielder Malory Masajilo helped seal the game for the Dons in the seventh inning by making a tough catch on a foul pop up between third base and home plate.
The victory over Granada (19-9) Saturday was Amador's seventh one-run win of the season.
Lotoszynski led the way at the plate, going 2-for-2 with a walk in the title game. Grauer and Molina also had two hits.
Amador's shortstop starred offensively throughout the tournament, batting 6-for-7 with four walks, six RBIs and three extra-base hits, including a home run against Castro Valley High in the quarterfinals.
Grauer no-hit Castro Valley in that opening game, an 11-0 victory in six innings on May 23. The Dons then beat crosstown rival Foothill High 7-1 in the semifinal round on May 28.
Amador finished its dominating 2014 campaign with 15 shutouts, including four 1-0 wins. The school last won a softball sectional title in 2011.
