It’s a case of no pain, no gain for Optimo…

The Bachata singer has notched his first Billboard chart-topper, as his single “Duele” rises 3-1 on the Tropical Airplay chart.

The song is the first official single from his set Amor De Guerra, which will be released on June 17.

The song grows by 32 percent in plays, with WXDJ Miami leading in spins (68) during the chart’s tracking week.

A recently released remix of the song featuring urban star J Alvarez has helped champion it on-air.

Optimo previously existed as a band under different formations, but has since been continued as a solo effort by vocalist Alixandro R. Sanchez under the same moniker.
