Jaron "Boots" Ennis defended his IBF welterweight title with a TKO victory over David Avanesyan Saturday night at the Wells Fargo Center in Philadelphia.

Ennis knocked down Avanesyan in the fifth round and the challenger looked spent as he headed back to the corner.

Before the sixth round started, the referee stopped the fight on the advice of the ringside physician.

"I knew I was too strong for him," Ennis said. "I should have listened to my corner a little more. Jabbed a little more, got to that body a little more, more angles. … It’s OK."

It was the first title defense for Ennis, 27, who improved to 32-0 and reinforced his status as one of the top rising stars in boxing. He has scored knockouts in 29 of his fights.

Ennis, a native of Philadelphia, was fighting in front of a hometown crowd of about 14,000 after a year-long layoff.

"I did feel a little off," he said. "That’s OK, I did get the job done."

Fighting, and winning, in his hometown "felt phenomenal," he said.

Ennis indicated he’d like to fight Terence Crawford even if it requires Ennis to move up to 154 pounds from his current spot at 147 pounds.

“I want the big names,’’ he said.

Avanesyan, 35, called this fight his last shot at a world title. He fell to 30-5-1.
