Former three-division world champion Miguel Cotto of Puerto Rico stopped Delvin Rodriguez in the third round of their junior middleweight main event Saturday at Amway Center in Orlando, Fla.

After hurting Rodriguez near the end of the second round, Cotto decked Rodriguez at the outset of the third, the fight ending only 18 seconds into the round.

Cotto, who was trained by Freddie Roach for the first time, is 38-4 with 31 knockouts. Rodriguez, of Danbury, Conn., via the Dominican Republic, is 28-7-3 with 16 knockouts.

Former world champion Miguel Cotto of Puerto Rico will get back into the ring for the first time since last December when he takes on Delvin Rodriguez in the super welterweight main event Oct. 5 at Amway Center in Orlando, Fla. (on HBO).

Cotto, 32, has won titles in three weight classes. But he has lost his past two fights – against Floyd Mayweather Jr. and Austin Trout – and is looking to get back into the win column and back in contention for another title.

“I am very happy to be back on Oct. 5 and fighting in front of all the great fans in Orlando,” said Cotto, who is 37-4 with 30 knockouts.

Whereas Cotto has won championships, Rodriguez (28-6-3, 16 KOs) is in search of his first.

“I’m going to go for the knockout,” said Rodriguez, of Danbury, Conn. via the Dominican Republic. “I will take advantage of the biggest opportunity of my life.”
