Rolando Romero simply had too much power for Anthony Yigit.
Romero put his Swedish opponent down three times and stopped him in Round 7 in a scheduled 12-round lightweight bout Saturday on the Jermell Charlo-Brian Castano card at AT&T Center in San Antonio.
Yigit, who took the fight on short notice and came in overweight, began taking heavy punches early in the fight but used good movement to stay out of serious trouble.
However, by Round 5, the hard blows began to break Yigit down. Romero lost a point in that round for punching on the break but moments later put Yigit down and hurt him with a right hand that landed a split second before the bell.
Yigit (24-2-1, 8 KOs) was able to survive in Round 6 by holding and moving but the writing seemed to be on the wall. In the following round, Romero (14-0, 12 KOs) put Yigit on the canvas again with a short right and then stopped him with a right-left combination.
The official time of the knockout was 1:54 of Round 7.
Romero was asked afterward who he would like to face next and he mentioned one of the most-dangerous fighters on the planet, fellow 135-pound contender Gervonta Davis.
Power vs. power. Something would have to give.
