SportyTV | NBA: Thunder, Spurs advance to NBA Cup semifinals

Shai Gilgeous-Alexander scored 28 points and the Oklahoma City Thunder matched the best 25-game start to an NBA season with an easy 138-89 rout of the Phoenix Suns in an NBA Cup quarterfinal on Wednesday night.

The Thunder's 24-1 mark ties the 2015-16 Golden State Warriors, who won their first 24 games before finally losing.

Chet Holmgren added 24 points and eight rebounds and Jalen Williams had 15 points for the Thunder, who set a franchise record with their 16th straight win. They advanced to the semifinals on Saturday against the San Antonio Spurs.

It seemed this could be a tough one for the Thunder. Oklahoma City’s 123-119 win over the Suns in NBA Cup group play on November 28 was its closest game during their win streak.

But Phoenix star Devin Booker missed his third straight game with a strained right groin. He scored 21 points in the previous matchup and said in the postgame that the “secret is out” about the Thunder’s league-leading defence.

It appears the Suns have more to learn. They shot 39.3% from the field and scored a season-low point total. Dillon Brooks led the Suns with 16 points, but he made just 4 of 16 shots.

It was Gilgeous-Alexander's 96th straight game with at least 20 points. He reached the total on a breakaway dunk that put the Thunder up 84-50 with 9:15 left in the third quarter.

Castle, Fox lead Spurs to semifinals

Stephon Castle scored 21 of his 30 points in the second half, and De'Aaron Fox added 20 points in the San Antonio Spurs' 132-119 victory over the Los Angeles Lakers in an NBA Cup quarterfinal.

Keldon Johnson had 17 points and eight rebounds as the Spurs maintained a healthy double-digit lead for most of the final three quarters to claim the last Cup semifinal spot in Las Vegas, where they will face the NBA-leading Oklahoma City Thunder on Saturday.

Luka Doncic scored 35 points and LeBron James had 19 points, 15 rebounds and eight assists for the Lakers, who lost for only the third time in 12 games. Los Angeles trimmed the deficit to eight points late in the fourth quarter but couldn't get closer.

Marcus Smart scored a season-high 26 points with eight 3-pointers for the Lakers, and Austin Reaves had 15 points.

San Antonio have won nine of 12 overall after steadily controlling this meeting of two Western Conference teams hoping to challenge the defending champion Thunder, both this week and in the postseason.
