Basketball: Kiwi Charlisse Leger-Walker nails buzzer-beating lay-up as Washington State upset Arizona in NCAA

Kiwi Charlisse Leger-Walker has sunk a sensational buzzer-beater for Washington State in an overtime US college basketball win over Arizona.

The 19-year-old nailed a lay-up in traffic to secure a stunning comeback win and an excellent personal performance, finishing with 17 points and five assists.

Leger-Walker's Washington State trailed by as many as 16 points against the US seventh-ranked Wildcats. 

"Those who know me know I don’t get too high or too low, but when I made that shot, I was so high," she says.

"Just to get that final shot go in was so amazing, and I’m so glad my teammates had the trust in me to let me try and make that play."

Leger-Walker kept her side in the contest in regulation time, converting a lay-up with less than two seconds on the clock, after an assist from sister Krystal. 

The Waikato pair then combined for eight of Washington's 11 overtime points. 

The Cougars have now won their last four outings, after they were predicted to struggle in the Pac-12 conference this season, and they should now find themselves with a national ranking.

"I couldn’t be happier for this team, and where we are going and the future of this programme," coach Kamie Ethrdige says.

"We put the ball in Charlie’s hands and gave her space so she could at least attack the rim at the buzzer and it won us the game."

The sisters’ mother - Leanne Walker - captained the Tall Ferns at the 2004 Athens Olympics.
