In the bottom of the ninth inning, with the Yankees clinging to a one-run lead, Mariano Rivera stepped onto the mound. The stadium was electric, a sea of pinstripes and flashing lights. Rivera, the embodiment of calm, delivered his signature pitch. The ball spun rapidly, darting towards the batter before veering sharply inside. The bat shattered on impact, a helpless grounder rolled to second base. Game over. Another save. Another triumph for Rivera and his devastating cutter.
