Tyus Jones hit two free throws with .4 seconds remaining as the Minnesota Timberwolves scored their most improbable victory in their unexpected run in the NBA Las Vegas Summer League tournament Saturday, beating Toronto 81-79.

Trailing the top-seeded and unbeaten Raptors by as many as 14 points in a quarterfinal game, Minnesota chipped away and eventually tied the game at 70 with 4:12 to play. Toronto scored the next six points and the Wolves followed with a 9-0 run before the Raptors' Norman Powell tied it with a 3 with 20 seconds left. After having the ball knocked away on a drive with 1.1 seconds remaining, Jones was then fouled on a shot, leading to the game-winning free throws.

The Wolves led 20-15 after one quarter but the Raptors used a 14-0 run to take the lead and outscored the Wolves 27-14 in the second quarter.
