Riasco made his professional debut on 25 August 1968 with a four-round draw with Carlos Mendoza and after winning the featherweight national championship, he fought Alexis Argüello, who defeated him with a second round technical knockout.
After his defeat, he defeated previously unbeaten Luis Ávila and Puerto Rican Santos Luis Rivera, who had knocked him out in the first round in Puerto Rico. Those victories earned him the chance to fight for the newly created WBC championship belt.
On 3 April 1976, Riasco defeated Kenyan Waruinge Nakayama for the WBC and Lineal Super bantamweight titles. He made two successful defenses against Livio Nolasco and Dong Kyun Yum before losing his belt in his third defense against Japanese Royal Kobayashi in Tokyo on October 9, 1976.
He announced his retirement in 1981, but returned later. After three consecutive defeats, Riasco officially announced his retirement in 1982. He left with a record of 29 wins with 13 KOs, 9 losses, and 4 draws.[3]
