Chelsea Gray is going to play a big-time basketball game on Sunday with her very best childhood friend on the other side.

And that just adds a little extra spice to the mix, as No. 4 Duke (4-0) gets its first real home-court challenge this season when No. 10 California (6-0) visits Cameron Indoor Stadium at 2 p.m.

Gray and Calโ€™s 6-foot junior guard Afure Jemerigbe have been good friends since elementary school, and three years ago they experienced a real high when the McDonaldโ€™s All-Americans led Stockton St. Maryโ€™s to a 34-1 record and the Golden Stateโ€™s Class 6A state title.

Gray, an accomplished stat-sheet stuffer, is averaging 16.4 points, 7.0 assists, 5.0 rebounds and 3.6 steals. Jemerigbe averages 9.5 points and 2.5 rebounds on a team with five averaging in double figures.

โ€œWeโ€™ve never played against each other (at this level),โ€ explained Gray, whose cousin Alexis Gray-Lawson starred for the Bears before playing in the WNBA. โ€œBut Iโ€™m excited about it. My mom will be here โ€” Afure is like a second daughter to her.

โ€œCal was in my top five (on her recruiting list). The previous coach, Joanne Boyle (now at Virginia), and I have a pretty good relationship. And I always went to a whole lot of games with my cousin being there.โ€

Itโ€™s the first of a two-year contract with the Bears.

โ€œWeโ€™ve got to take Chelsea back (next season for a โ€˜homecomingโ€™ game) so that seemed like a nice match,โ€ Duke coach Joanne P. McCallie said.

โ€œChelsea is more mature than she was at this time last year. Sheโ€™s really dictating and making great decisions. Her assist-to-turnover ratio is 5-to-1. To be an All-American point guard youโ€™ve got to empower everybody. And sheโ€™s also mentoring Lex (freshman Alexis Jones). Chelsea is the best in the country. I donโ€™t accept that anyone is better than she is.โ€

Gray, of course, was happy to hear her coachโ€™s nice words.

โ€œThose are some big words to fulfill when she says that,โ€ Gray said. โ€œI thank her for that compliment. But thereโ€™s always room for improvement defensively and offensively.โ€

With an array of injuries Duke had been limited to nine players including scrappy, charismatic sophomore walk-on Jenna Frush through the first three games.

But forward Richa Jackson got on for one minute at Michigan on Wednesday night, and point guard Chloe Wells may be ready for some minutes against the Bears.

โ€œRicha (knee) is cleared to play but not quite in condition to play โ€“ she might play 10 minutes,โ€ McCallie said. โ€œIโ€™m trying to get Chloe (leg) cleared. She wonโ€™t play a ton of minutes, but weโ€™re kind of hopeful there. Iโ€™d like to see both of them, because they look great in practice.โ€
