PARIS — Lauren Betts had 18 points and four blocks as No. 5 UCLA beat No. 17 Louisville 66-59 in a season-opening doubleheader in France on Monday.

Timea Gardiner had 15 points and Londynn Jones contributed 13 for UCLA.

Tajianna Roberts had a game-high 21 points for Louisville, which opened up an 18-13 lead at the end of the first quarter but then proved wasteful in attack.

Louisville was 6 of 29 from 3-point range compared to 8 of 23 for UCLA. Gardiner made five of them and Jones was a perfect 4 of 4 from the free-throw line.

The 8,000-capacity Adidas Arena, home to the men’s Paris Basketball team, was just over half full for the second game.

The imposing physicality of Betts and Gardiner on defense did much to contain Louisville’s speedy attacks. The standout pair also combined at the other end for Gardiner’s neat 3-pointer from wide right late in the game.

Betts shot 75% (9 of 12).
