We are deeply saddened by the passing of Sam Wopat, said athletic director Bob Bowlsby. She was an integral member of the Stanford athletics family and a tremendous student and athlete...Stanford University and the women's volleyball program have lost a wonderful young woman.

The 19-year-old graduated from Dos Pueblos High School in Goleta (Santa Barbara County) and was considered one of the nation's top players. She joined the Stanford team in 2010 with her twin sister Carly as an outside hitter. As a freshman, she saw action in 11 sets, while she appeared in 25 sets as a sophomore.

Wopat played on the 2010 U.S. junior volleyball national team, a year after playing on the youth national team that competed at the world championships in Thailand. She was a member of three junior Olympic volleyball teams.

The 2011 Stanford volleyball team finished tied for fourth in the Pac-12 with a 15-7 record and was eliminated by Michigan in the second round of the NCAA tournament.

Wopat is survived by her parents, Ron and Kathy of Santa Barbara, her sister Carly and her younger brothers Jackson and Eli.
