LOS ANGELES – Diego De La Hoya shook off some ring rust and recorded a knockout Saturday in his first fight in 2½ years.

De La Hoya, a cousin of Oscar De La Hoya, stopped Mexican journeyman Enrique Bernache in the fourth round of a featherweight fight scheduled for 10 rounds on the Ryan Garcia-Javier Fortuna undercard at Crypto.com Arena. Bernache was hurt, but still on his feet when referee Ray Corona halted the action with nine seconds to go in the fourth round.
