As the sister of a Super Bowl-winning quarterback, Anna Wilson might be one of the more visible players on Stanford’s 14th-ranked women’s basketball team.

The sophomore guard played limited minutes in the Cardinal’s first three games, though, and she hadn’t scored entering Sunday’s game against Cal State Bakersfield. With Stanford’s top player, Brittany McPhee, out with a foot injury, Wilson came off the bench for nine first-half points in the Cardinal’s 57-34 win over Cal State Bakersfield.

Another guard, Alexa Romano, contributed a career- and game-high 13 points and the two combined to go 6-for-15 from three-point range.

“Anna and Alexa really helped us,” Stanford head coach Tara VanDerveer said, noting that neither had a turnover in a game in which the Cardinal gave away the ball 15 times. “Really knocking down some threes for us.”

Wilson, the younger sister of Seattle quarterback Russell Wilson, played only 48 minutes in six games as a freshman because of a concussion and then a foot injury, and she averaged 2.8 points per game. In Stanford’s first three games, she played 24 minutes and went 0-for-5 from the floor.

Wilson said last season wasn’t frustrating; she described it as “bumps in the road.” She added, “Seeing my shot fall after last year is obviously awesome. … I’m just trying to work hard and staying with things, and I’m happy we won.”

“She’s really special on our team,” VanDerveer said. “She has a great sense of basketball. There’s a plan and she believes in the plan and she’s making the most of it every day. She’s a leader on our team, as is Alexa, with how hard they work. Keeping her healthy is at the top of the list.”

McPhee injured her foot in Stanford’s exhibition game and played in subsequent games against Ohio State and UConn before sitting out Friday’s win over UC Riverside. VanDerveer said that McPhee is “day to day, week to week. It’s important for her to heal 100 percent because we’re going to need her down the stretch.”

That means more action for Stanford’s young players; McPhee is one of only two seniors. Nine players were on the court for 13 minutes or more Sunday.

“There are so many young players, and we’re asking them to do different things,” VanDerveer said. “For us to play nine people double digits. ... That’s not happened in a long time. It’s great other people are saying, ‘Hey, I want to be out there.’”

The Cardinal blazed to a 9-0 lead Sunday and held the Roadrunners without a point for the first 3:54, and kept pouring it on from there to go into the half with a 36-16 lead. Stanford’s one trouble area: The Cardinal committed 11 turnovers in the half.

“It was kind of a story of two halves,” VanDerveer said. “In the first half, we shot the ball really well and turned it over like crazy. In the second half, we took care of the ball and didn’t shoot as well.”

Sophomore guard DiJonai Carrington had a game-high seven rebounds and she and Marta Sniezek each had five assists.

Daije Harris came off the bench to lead Cal State Bakersfield (1-2) with 10 points. The Roadrunners shot 24 percent from the floor, making 12 of 50 shots, and Stanford held a 44-30 edge on the boards.

Stanford is 2-2 this season. The Cardinal are 4-0 all-time against Cal State Bakersfield.
