Danny Garcia ceased Brandon Rios with a correct submit the ninth round Saturday night in their WBC welterweight world title end session.
Garcia (34-1, 20 KOs) beat Rios (34-4-1, 25 KOs) at Mandalay Bay Events Center to set up a potential rematch against WBC and WBA champion Keith Thurman or a battle against IBF champion Errol Spence Jr.
Garcia battled out of the blue since losing the WBC title in a unification battle with Thurman in March.
"I felt the ring rust a tad initially," the Philadelphia contender said. "He's a decent inside warrior and he was giving me some great uppercuts. He came to battle. I came to box, and I did that. I came to blast, and I gave the fans what they needed — a knockout."
Rios could get recovered, yet lurched toward arbitrator Kenny Bayless, who waved off the battle at the 2:25 characteristic of the round.
"I'm distraught," Rios said. "I don't care for going out that way. I'm a warrior, I got go down and I needed to proceed. I figure the corner halted it yet I'm distraught. I'm distraught on the grounds that I got up still. I'm a warrior. I'm still in the diversion. I didn't figure he did much to hurt me."
Garcia, from Philadelphia, was the title holder for a long time dating to his prevail upon Hall of Famer Erik Morales in 2012 through the March misfortune. Rios, from Oxnard, California, is a previous lightweight champion.

The judges scored it 120-108, 120-108 and 119-109. The battle was a rematch of last September's session in which Benavidez won the world title.
Benavidez, from Phoenix, landed 315 punches to Gavril's 176 and associated on 41 percent of his energy shots.
"I knew he would turn out forceful," Benavidez said. "I knew I could hit and box him throughout the day. When I saw the opening I took it. I didn't thump him out however. He's an extreme child of a weapon."
In an undercard IBF 147-pound title eliminator between two welterweight contenders, Yordenis Ugas (21-3, 10 KOs) ceased Ray Robinson (24-3, 12 KOs) in the seventh.
