Victor Wembanyama delivered the kind of highlight that reminds the NBA why he is one of basketball’s most extraordinary talents. The San Antonio Spurs center threw down a one-handed alley-oop dunk through contact from P.J. Washington, converted the and-one opportunity and helped his team secure its first victory of the season. Wembanyama connected with De’Aaron Fox on a give-and-go before soaring toward the rim and finishing the lob with one hand over Washington. The spectacular play gave the Spurs a statement moment in their 122-106 victory over the Dallas Mavericks on Saturday night at American Airlines Center.
