Donald Curry, 24, knocked out Eduardo Rodriguez, 26, with a combination to the head in the second round and kept his undisputed welterweight title before a loud crowd of 8,000 hometown fans in Fort Worth. Rodriguez was counted out at 2:29 and was down five minutes after that. Curry is 25-0 with 20 knockouts. . . .

Yoo Myong-woo, 21, of South Korea won a unanimous 15-round decision over Jose de Jesus of Puerto Rico and retained his World Boxing Association junior flyweight crown in Seoul. . . .

Left-hander Robbie Sims, 26, of Brockton, Mass., looking to build his reputation as someone other than Marvelous Marvin Hagler's half-brother, put John Collins down twice and bloodied his nose, all in the 2:46 before the fight in Las Vegas was stopped. Sims (26-4-1) earned the USBA middleweight title.

"No excuses. I didn't fight my fight," Collins said. But he got $60,000 to Sims' $35,000. That will change, promoter Bob Arum said. "Anybody who wants a crack at Marvin Hagler has to go through Robbie Sims," Arum said. . . .

Lightweight Pernell Whitaker broke his left hand but still won a unanimous decision over John Montes in Hampton, Va. Whitaker is 8-0 after going 10 rounds for the first time.

"I hurt my hand around the fourth round," he said. "It kind of froze up from that point on. I never stopped throwing it. I just wasn't throwing it with authority."

On the undercard, junior lightweight Floyd Favors of Capitol Heights fought Kent Hardy of Detroit to an eight-round draw. Favors is 8-0-1.
