JOHNSON CITY — The effort was there, but this time there was no magic. Two nights after the East Tennessee State volleyball team beat Tennessee, the women’s soccer team faced a tougher task. Tennessee, ranked ninth in the country, remained undefeated as international star Bunny Shaw scored her first two goals of the college season in a 4-0 victory over the Bucs on Thursday night at Summers-Taylor Stadium. Shaw plays for the Jamaican national team and leads the entire world in goals during World Cup qualifying with 16 in eight games.
