The second-ranked Stanford women's soccer team extended the nation's longest active winning streak in Division I to nine games, earning a 3-0 victory over host Utah on Thursday in Pac-12 Conference play.
The Cardinal (11-1, 4-0) travel to Colorado for a noon contest on Sunday.
"When the ball goes into the back of the net all we want is to get another one," Carusa told Pac-12 Networks. "Our defense absolutely makes us a better offense."
After hitting the post in the 23rd minute with a driven effort from the top of the box, DiBiasi opened the scoring in the 27th minute.
Sacred Heart Prep grad Tierna Davidson switched the field to Tegan McGrady, who picked out DiBiasi's run into the box with a perfect cross. DiBiasi's powerful header left the keeper no chance, and it was her third goal in as many games.
It was DiBiasi's 16th career goal, of which nine have been game winners. Stanford has 51 goals on the year, matching its total from last season.
Stanford started the second half brightly, with two chances by Catarina Macario to make it 2-0. The Cardinal doubled its lead on 53 minutes through Xiao. Xiao picked up the ball at the halfway line, beat several defenders and thumped a shot inside the far post for her third strike in two games.
Four minutes later, Carusa put the game to bed with a calm finish in the box after Andi Sullivan's long attempt deflected off a Utah boot. It was Carusa's ninth goal of the season, tying her with Macario for the team lead.
"We have a deep bench," Carusa said. "We have girts going in who make a difference every single minute they're in the game. That makes you think ' have to be helping the team. I have to be playing well.'"
Macario led the Cardinal with five shots, including three on goal, and Xiao, DiBiasi and Sullivan each attempted two shots.
Melissa Lord dropped a 6-3, 6-4 decision to USC's Gabby Smith in her main draw singles opener on Thursday afternoon at the Riviera/ITA All-American Championships.
The lone Cardinal player remaining in the tournament, Lord moves into the consolation draw and will next face Georgia's Elena Christofi on Friday at 12:30 p.m.
