Jonas Valanciunas was the best player on the floor as Lithuania humiliated the United States 108-75 in a tuneup for the FIBA under-19 championship, which gets underway on Thursday in Latvia.

The fifth overall selection by the Raptors imposed his will on the smaller Americans, compiling a game-high 23 points and 11 rebounds, along with two blocks and a steal.

Valanciunas is rail-thin and must pack on 15-25 pounds before he can compete effectively in the NBA, but against those his own age, he has consistently dominated.

Previously, Valanciunas was named MVP of FIBA’s under-18 and under-16 tournaments.
