21. Kurt Angle vs. Rey Mysterio: SummerSlam 2002
One of the best opening matches in SummerSlam history, Kurt Angle and Rey Mysterio put on an excellent match in 2002 in Uniondale, N.Y.
Mysterio hit Angle with everything, but he couldn’t put him away. Kurt would counter a top-rope frankensteiner attempt and then lock in his vaunted ankle lock, forcing Mysterio to submit.
This was a great way to open what would go on to be one of the better overall SummerSlam events in WWE history.
