Victor Wembanyama garners a ton of hype — rightfully so — for his unprecedented offensive skill set.

On Sunday, the French phenom showcased his defensive prowess to secure a spot for Boulogne-Levallois Metropolitans 92 in the Ligue Nationale de Basket (LNB) Finals.

Wembanyama tallied 5 blocks as Metropolitans 92 defeated Lyon-Villeurbanne (ASVEL), 71-69 in Game 4 of the semifinal series. With the victory, they secured a 3-1 series win to advance to the championship series of France's top basketball league against Monaco.

Wembanyama's final block helped fend off an ASVEL rally from a 55-43 third-quarter deficit. ASVEL posted a 24-10 run to briefly take the lead at 67-65 late in the fourth quarter. But Metropolitans 92 scored 5 unanswered points, and Wembanyama sent back an Alex Tyus layup attempt that would have cut his team's lead to 70-69 in the final minute.

Instead, Metropolitans 92 maintained the 3-point edge and held on for the 2-point victory down the stretch.

Wembanyama showcased his otherworldly athleticism earlier in the game with a two-handed block to send back a dunk attempt that had intentions of putting him on a poster.

He finished with 15 points, 7 rebounds, 5 blocks and 1 steal.

After the game, he posted a celebratory message on Twitter.

Game 1 of the best-of-five championship series against Monaco is scheduled for Saturday.

Former Kansas State standout Barry Brown Jr. led Metropolitans 92 with 18 points, while Bilal Coulibaly added 16 points, 4 assists, 2 rebounds and 2 steals. A 6-foot-6 shooting guard, Coulibaly is a rising NBA prospect who's expected to join Wembanyama in the first round of the June 22 NBA Draft.

As for Wembanyama, there's not doubt about his status. The San Antonio Spurs won the draft lottery and will select the generational prospect with the No. 1 overall pick and hope that he anchors the franchise for the next decade or more.
