No. 13 Stanford women overpower Arizona 77-47

After starting the first 10 games, Stanford forward Erica “Bird” McCall was relegated to a reserve role. Maybe part of the problem was she couldn’t see the basket.

The 6-foot-3 sophomore forward had ditched her goggles before the season started because they felt uncomfortable, and she said she had trouble finding suitable contact lenses.

In the past two games, though, she has worn horned-rim glasses. Against Arizona on Friday night, she said, they helped greatly in the No. 13 Cardinal’s 77-47 victory at Maples Pavilion.

“They give me confidence — they help me see better,” she said after posting her first collegiate double-double (13 points, 16 rebounds). She also blocked three shots.

“I’m excited about how Bird played,” coach Tara VanDerveer said. “She had a great week of practice. … When people practice well, they play well.”

McCall entered the game averaging 4.9 points and 5.1 rebounds, both numbers below what Stanford had expected of her in her second year.

Maybe Friday’s game marks the beginning of an upturn for McCall. She said she “really got down on myself” this season, but her coaches and teammates have helped pick up her spirits, she said.

The Cardinal (13-4, 5-0 Pac-12) enjoyed their first Pac-12 rout of the season at the expense of the Wildcats (7-9, 0-5), who haven’t beaten Stanford in their past 25 tries.

Next up for Stanford, though, is a 3 p.m. game Monday against No. 14 Arizona State, with whom it shares first place in the conference.

Sisters Bonnie and Karlie Samuelson each hit four three-pointers as Stanford won its seventh straight game. Stanford, the fourth-best three-point shooting team in the country at 40 percent, sank 9 of 19 long-range shots.

Until Friday night, guards Lili Thompson and Amber Orrange had scored 51 percent of Stanford’s points in conference play. But this time, Bonnie Samuelson had 14 points, while Karlie Samuelson, Thompson and backup guard Briana Roberson — who matched her career high — had 12 points each.
