Freshman guard Brandon Randolph scored 21 points off the bench to lead Arizona in a 113-44 rout of Combinado Valenciano on Sunday in the Wildcats’ first game of their Spanish exhibition tour.

Dusan Ristic added 14 rebounds, while Allonzo Trier had 16 points, Dylan Smith scored 14 and both Rawle Alkins and DeAndre Ayton had 10.

The win was UA’s biggest victory margin ever in a foreign exhibition game.

A big scoring guard from Yonkers, New York, Randolph is expected to compete for considerable playing time in reserve next season while UA coach Sean Miller went with the same starting lineup that he’s expected to in November: Parker Jackson-Cartwright, Trier, Alkins, Ayton and Ristic.

Arizona will next face another collection of players, the Mataro All-Stars, on Wednesday at 10:10 a.m. Tucson time. The Wildcats will travel to Barcelona on Monday and visit the 1992 Olympic facilities on Tuesday. Games will not be televised on broadcast on radio, but can be streamed on FloHoops.com for a fee.

• Duke basketball coach Mike Krzyzewski has undergone knee replacement surgery. Team spokesman Cory Walton says the procedure on his right knee was performed Sunday by Dr. Michael Bolognesi at the university’s hospital.

Bolognesi says the surgery went “very smoothly,” and doctors hoped to have the Hall of Fame coach walking later in the day. He’s expected to be released within one to three days to begin a rehabilitation program at Duke.

The surgery led Duke to cancel the exhibition trip to the Dominican Republic that was scheduled to begin this week. Krzyzewski opted for surgery after determining his knee condition “wouldn’t be sustainable” through the season. Krzyzewski has had both of his knees replaced in the past 17 months, with six total surgeries in that span.

Larson continues Michigan mastery

BROOKLYN, Mich. — Kyle Larson slipped between cars on an overtime restart, capping his wild weekend with a victory in Sunday’s NASCAR Cup Series race at Michigan International Speedway.

Larson was in the spotlight after team owner Chip Ganassi allowed him to go to Iowa to compete in the Knoxville Nationals on Saturday. He finished second at that sprint car event before returning to Michigan and earning his third Cup victory of the season. He has won the last three Cup races at MIS, the first driver to do that since Bill Elliott, who won four straight from 1985-86.

Furniture Row Racing teammates Martin Truex Jr. and Erik Jones finished second and third. Larson won by 0.31 seconds in his No. 42 Chevrolet. Brad Keselowski and Truex won the first two stages.

Zverev upsets Federer for title

MONTREAL — Alexander Zverev kept his winning streak alive with a 6-3, 6-4 victory over Swiss ace Roger Federer in the Rogers Cup final on Sunday.

The 20-year-old Zverev, the winner last week in Washington, D.C., posted a 10th straight match victory and ended the 36-year-old Federer’s winning streak at 16. The German also tied Federer with a fifth tournament victory this year.

Zverev, the youngest Rogers Cup finalist since Novak Djokovic in 2007, was coming off an emotional victory over Canadian teenager Denis Shapovalov in the semifinals.

Allyson Felix earned a second gold medal on Sunday and highlighted the overwhelming performance of the United States at the 10-day world championships.

In doing so, Felix made sure she became the most decorated athlete in the history of the event — and that includes Usain Bolt.

Felix won gold in the 4x400-meter relay a day after winning the same color medal in the 4x100 relay. She also earned a bronze medal in the 400-meter race to give her 16 in her career. Bolt finished his career with 14.In a world championship of upsets right up to the last event, Trinidad and Tobago beat the United States in the men’s 4x400, producing only a little dent in an all-powerful performance.

The Americans finished with 30 medals, 10 of them gold. That was only one short of the overall record held by East Germany.
