SYDNEY, Australia (AP) -- Jermain Taylor, an auto mechanic from Little Rock, Ark., knocked down his Bulgarian opponent with a crunching right Tuesday and became the eighth American boxer to advance at the Olympics.

 As Dimitriy Usagin started to throw a right, the 22-year-old Taylor whipped his right to the jaw and Usagin crashed to the canvas. He struggled up, took a few tottering steps, fell into the ring post, and the 156-pound bout was over with 10 seconds left in the first round.

 Jose Navarro of Los Angeles advanced at 112 pounds by outpointing Hermensen Ballo of Indonesia 16-10. Watching and shouting instruction was Navarro's older brother, Carlos, who failed to make the 1996 Olympic team, but who is 22-1 as a pro featherweight.

 Ricardo Williams Jr. of Cincinnati boxes Henry Collins of Australia at 139 pounds Wednesday (Tuesday night EDT); heavyweight Michael Bennett of Chicago boxes Wojciech Bartnik of Poland Thursday (Wednesday night EDT); super heavyweight Calvin Brock of Charlotte, N.C., meets Paolo Vidoz of Italy Saturday, and Olanda Anderson of the Army fights Rudolf Kraj of Czech Republic on Sunday (Saturday night EDT).

 The first seven Cubans to box also have won. The last two both won easily: Juan Hernandez, an Olympic silver medalist in 1992-96 and a four-time world champion at 147 pounds, boxing at 156, and Manuel Mantilla at 112.

 The great heavyweight Felix Savon, who could box Bennett in the quarterfinals, also fights Thursday afternoon (Wednesday night EDT).

 Taylor, who says "I can fix anything," wrecked Usagin's medal hopes with five rights to the head, the last ending the match in spectacular fashion.

 While the 19-year-old Navarro, the youngest of 12 children, needs to win more bouts to get a gold medal, he already has achieved one goal.

 "When my brother didn't make it, it was the last chance in my family, and I wasn't going to let them down," he said upon qualifying for the Olympics.

 Navarro said he could hear his brother during the bout.

 "I could hear him telling me to throw the 1-2, and I did that," Navarro said. "He knows what he's talking about."

 Navarro, however, was lacking fatherly advice, because Carlos Sr. missed his flight.

 The left-handed Navarro led only 7-6 after two rounds,

 "I felt a little tense at the beginning of the fight," he said. "I picked it up in the third round. These are the Olympics. I have no choice but to pick it up or you go home."

 Navarro found the range with his right in the third round and outscored Ballo 6-1 to make the scored 13-7.

 Navarro's second-round opponent will be Hickem Mesbahi of Morocco.
