Surrounded by jubilant Acalanes classmates and pelted by the pouring rain, senior lineman Jack Manful proudly waved a large white flag emblazoned with the Dons’ signature “A” logo before spearing it into Campolindo’s soggy logo at midfield.

After watching the Cougars plant their flag at Acalanes a season ago, Manful and the rest of the Dons seniors had waited a whole year for revenge, which came in the form of a 21-12 victory in Moraga on Friday night.

It was the Lafayette school’s first win over its rival since 2019.

“This felt so good,” Manful said. “We lost to these guys three years in a row, and it felt great, in my senior year, to just put that flag down and show them what we worked for all season.”

The win for Acalanes (7-2, 3-0) clinched at least a share of the Diablo Athletic League Foothill Division title. The Dons can capture their first unshared league crown since 1981 with a win over Las Lomas next week.

Acalanes relied on running back Josh Elerts and his 182 rushing yards to help lead the way.

“This was very sweet,” coach Floyd Burnsed said. “Especially here on their senior night and all that good stuff, that makes it extra special.“
