The war of words was over and the fight was on.
Miguel Cotto absorbed a relentless attack from Ricardo Mayorga, avoiding the urge to turn the fight into a brawl and saving his best punch for the final round as he knocked down Mayorga in the 12th round and retained his 154-pound title.
Cotto fought with discipline for 11 rounds before unleashing a vicious left hook in the 12th round Saturday night against the wild-swinging Mayorga.
The hook dropped Mayorga to the canvas and he quit a few seconds later, ending an entertaining bout between two boxers trying to resurrect their careers.
"It was a really good fight with an amazing finish," Cotto said.
Cotto was ahead by five points on all three ringside scorecards entering the final round and seemingly headed to a win by decision. But he caught Mayorga in an exchange early in the round and, though Mayorga got up, he told referee Robert Byrd when action resumed that he couldn't go on.
Mayorga said it wasn't the effects of the left hook that made him quit, but an injury to his thumb during the exchange.
"I hate the way this fight ended," Mayorga said. "I tried to finish the final round but the pain in my hand was too much."
Cotto made Mayorga fight on his terms much of the night, frustrating the Nicaraguan and piling up points. The fight had plenty of action, but Cotto landed the cleaner and more effective punches as he stuck to his boxing style despite Mayorga begging him to brawl on several occasions.
Cotto was a big favorite to retain the title, but Mayorga fought a competitive fight and landed well in flurries to the head. He took more punches than he gave out, though, with Cotto outscoring him 249-176 in total punches scored at ringside.
"The game plan was not to get caught up in any of his antics," Cotto said. "He was very heavy handed, I felt his punches the whole fight."
Before the final round, Cotto's trainer, Emanuel Steward, told his fighter to make sure he kept going forward and that he could stop a tiring Mayorga. He did just that, though Cotto only had to remain on his feet in the final round to win.
"I told myself, keep calm and be myself," Cotto said. "He has very strong hands and punches that hurt."
Cotto, who made $1 million, improved to 36-2 with 29 knockouts. Mayorga, who has now lost five of his last nine fights and may be at the end of his career at the age of 37, fell to 29-8-1.
