Total Nonstop Action stages its annual day of reckoning, with scorpion master Sting and former teammate A.J. Styles resuming their off-again-on-again death duel for the world heavyweight championship. Bat-swinging vet Sting is eager to strike, but will upstart Styles grind him down for good? Held this year in Irvine, Calif., the colossal event also sees TNA warhorses Kurt Angle, Abyss and Samoa Joe stoking rivalries with a host of young turks.
