The same arena where Rosado begged to fight on despite a bloodied face is where Gatti rose to fame in the late 1990s for displaying the same type of mettle.
"People are knowing me everywhere I go," said Rosado (21-7, 13 knockouts). ". . . A lot of people feel like I'm kind of like the modern-day Gatti in a way."
Saturday's 10-round bout will be televised on Showtime as Rosado returns to junior middleweight against 23-year-old Jermell Charlo (22-0, 11 knockouts) at the D.C. Armory in Washington.
In January 2013 - Rosado's first fight of the year - he forfeited his No. 1 International Boxing Federation ranking at junior middleweight to vie for a shot at Gennady Golovkin's pair of middleweight world titles.
But Rosado's night came to a halt when Golovkin's powerful right hand opened a cut near Rosado's left eye. Rosado fought on for a few rounds until his trainer, Billy Briscoe, threw in the towel.
HBO's cameras caught Briscoe telling Rosado's father that he had to stop the fight or "your son's going to die."
It was a loss - Rosado's first in almost two years - but he gained credibility for his fighting despite being almost blind in one eye.
Controversy came in Rosado's next fight, in May, when he fought on pay-per-view in Las Vegas against J'Leon Love.
Rosado controlled the fight and knocked down Love in the sixth round. But Rosado lost by split decision.
The loss - later ruled a no-contest after Love failed a drug test - only swelled Rosado's following.
It also kept Rosado on premium television. October's Atlantic City bout was televised by Showtime. Espinoza said Rosado has become comfortable on camera and knows how to sell a fight.
"Gabriel is one of those fighters that combines boxing skill with an aggressive action style," Espinoza said.
The cut that forced the ringside doctor to end Rosado's October fight against Peter Quillin was a different cut, Rosado said, from the one he received against Golovkin.
Rosado saw a surgeon, who told him that the eye was "healing really great."
