Many of the other problems for the Argylls were self-induced.
Bishop Noll led 20-18 in the first set then scored four of its final five points on service errors by Madison-Grant. The Argylls finished with 13 service errors overall.
The Warriors were playing further back in serve return — as much as seven feet at times — and Holloway said his players did not do a good enough job adjusting.
"We just didn't execute our serves very well," he said. "We cut back on the errors (in the third set), but we didn't execute well."
The finish to the first set actually gave Madison-Grant confidence. The Argylls counted on improved serving and felt like they were playing as well or better than the Warriors in other areas.
But the second set played out almost as a replay of the first.
Madison-Grant fell behind 10-4 but rallied to take a 17-15 lead. The Warriors answered with a four-point run to regain control, and the Argylls pulled as close as 22-21 before Bishop Noll served out the set.
"They served extremely well," Holloway said. "That was probably the difference in the match. They executed their serves, and we didn't."
Cappello led the Warriors with 19 kills, and Asya Hobbs added nine. Madison-Grant senior Jessica Hull had 16 kills in the final match of her high school career, and freshman Chloe Stitt added 10. Senior Bethani Herniak added five blocks, and freshman Kenzie Stitt had 11 assists.
The Argylls lose five seniors — including Kayla Martin, Ballie Havens and Kayla Stanley — but also have several young players returning next season.
"I don't know if we're a young team or an old team," Holloway said. "All I know is we're a team. We'll see what happens (next year). We do have some talent coming back. You just never know."
