Cuba's Robeisy Ramirez has demolished Irish flyweight Michael Conlon to reach the gold medal bout.

Ramirez took his time in the opening round and studied the Irishman before unleashing a rapid torrent of combination punches, switching nicely from upstairs to downstairs.

Conlon made a strong start to the second, but the Cuban soon regained control of the bout and opened up a four-point advantage.

Ramirez did not let up in the third round and continued to pummel the Irishman, causing the referee to deliver a standing count.

The Cuban was very impressive in clinching a 20-10 decision.
