Brumbaugh (Scotts Valley HS) on her final hole, the par-four sixth, drove the green in one and two-putted for her second birdie in a row forcing a playoff with Northwestern's Lauren Weaver. Both players finished regulation play at seven-under par 209.
The final round playing partners each parred the first playoff hole, but after a tee shot in the water on the second hole, Weaver bogeyed and Brumbaugh rolled in a par to win the tournament.
"My confidence was definitely in my driver," said Brumbaugh, a junior from Scotts Valley, Calif., who won for the first time with her first 54-hole college tournament score under par. "I knew I needed the birdie on my last hole and I hit a great drive to the green. Then again on the second playoff hole I hit it right down the middle."
Freshman Kathleen Rojas shot a one-under 71 in the final-round and shot 215 (-1) for the tournament finishing in a tie for 7th place.
"More players on our team are starting to show that they can step up and perform at a high level," said San Jose State head coach John Dormann. "It's a great thing for our team."
