San Antonio Spurs: Keldon tomahawks Spain through the earth (VIDEO)

Team USA couldn't hit a three to save their lives to begin their game against Spain -- until San Antonio Spurs forward Keldon Johnson came to the rescue. A corner three by the newest Olympian triggered a run by the United States team that was badly needed at the time, and it wasn't even the biggest play in the game by the 21-year-old.

In the midst of a huge third quarter, Johnson ran the court on a fast break to extend the United States' run with a thunderous one-handed dunk off a Damian Lillard assist.

The basket counted for two of Keldon's 10 points in the third period, drawing a highlight package on the TV broadcast in the fourth quarter to show how he propelled the United States to a lead they wouldn't lose.

In his first game as an official member of Team USA's Olympic Team headed to Tokyo, Keldon was one of the best players on the court on both ends of the floor. Even when it looked like he was beaten on the defensive end, he showed the effort that got him selected in the first place.

By the end of the game, Johnson tallied 15 pts on a remarkable 7-of-8 shooting from the floor and nailed his only 3-pointer.

Johnson finished the night as Team USA's second-leading scorer to Lillard's 19, proving to the world that his promotion to the main team heading to the Olympics in a week was no mistake.

Johnson ended his night prematurely, fouling out on a defensive play in which he was hooked to the ground.

Gregg Popovich's Team USA squad finished their exhibitions 2-2 and will be facing France to tip of their official Olympic bid on Sunday, July 25 at 8 a.m. ET.
