In game two, the score was tied 5-5, but Hachmann's serves gave the Bobcats a 8-6 lead. North Harford battled to stay close and on Becca Simon's serve, drew even at 15 all.
The serves down the stretch by Hachmann and Daley, however, and kills by Roland and Tia Williams, propelled the Bobcats to the second game win.
Bel Air also led early in game three (5-2), but North Harford rode the serves of Sydney Billings to keep it close early. But with more serves from Billings, the Hawks took a 19-18 lead, their first lead in three games.
Morgan Knox (three aces and five kills) served the final five points of the game to put the Hawks in the win column.
In game four, Amanda Rodriguez (two kills, 22 assists and five aces) jumped Bel Air to a 6-2 lead with strong serves. The Bobcats maintained that four to five point advantage throughout and led 17-12 on the best point of the match that ended with a Williams kill. She had six kills in the match.
The Bobcats pulled away after that on Daley's serves and Daley's lone kill from the back row.
Hachmann then served out the match.
Jackie DeLuise added five kills and four aces in the win. Coach Markland also noted outstanding back row defense from Samantha Liberto and Consuelo Ezcurra.
Allyson Meil had 13 digs for the Hawks and Sam Pappas added two aces and four kills. Billings finished with three kills two aces and three assists.
"I think we played well, I think it's a good indicator of what we need to work on," Hawks coach Sheri Billings said. "We had a lot of nerves, they were very nervous."
