Coleman, Marquez score impressive KOs on ShoBox

Roger Mayweather is 2-0 as a trainer this weekend.On Thursday in Los Angeles, the former two-division titleholder's junior welterweight prospect Jessie Vargas scored a first-round knockout over a veteran opponent. On Friday, Mayweather's <i>other</i> 140-pound up-and-comer Tim Coleman scored an impressive third-round stoppage of seasoned Venezuelan spoiler Patrick Lopez in the main event of a Showtime-televised card in Santa Ynez, Calif.Coleman (18-1-1, 5 knockouts) stood his ground against Lopez (20-3, 9 KOs) and dropped the aggressive two-time Olympian in the second and third rounds with accurate right-hand counter punches. The second knockdown was produced by a powerful bolo-style right uppercut that landed flush on Lopez's chops, causing the game southpaw fall face-first to the canvas.Lopez, who scored well to Coleman's body after getting up from his second-round knockdown, made it to his feet but could not recover. Referee David Mendoza waved the bout off at 2:13 of the round when Lopez staggered forward and fell into the ropes during the 10 count.Coleman, a Las Vegas-based Baltimore native who sparred with Mayweather gym mate Vargas coming into Friday's bout, retained a regional title with his most impressive victory of his career.In the co-featured bout of the <i>ShoBox</i> broadcast, lightweight prospect Archie Ray Marquez stopped bigger but lesser talented Juan Santiago in the third round of an entertaining shootout.Marquez (11-0, 8 KOs), a 22-year-old Albuquerque native, dropped Santiago (13-5-1, 8 KOs) with a right hand at the end of the second round after backing the 25-year-old Denver native to the ropes with a two-fisted assault. Marquez quickly picked up where he left off in the third, overwhelming Santiago 11 seconds into to the round.
