Wembanyama, 18, flew to Nevada with his French league team to showcase the skills that many informed observers believe will make him the number one pick in next year's NBA draft.
Around 200 NBA team representatives and more than 70 media outlets were on hand for the teenager's first ever match on US soil as he led the Metropolitans, based in the Paris suburbs of Boulogne-Levallois, against G League team Ignite.
Despite facing another hot NBA prospect, Scoot Henderson, the 7ft 4in Wembanyama grabbed 37 points and made five blocks as his team went down to a 122-115 loss.
Wembanyama followed up that eye-catching debut with another masterpiece on Thursday, scoring 36 points with 11 rebounds, four blocks and four assists in a 112-106 win over the Ignite.
