Double Olympic gold medalist Usain Bolt, who won the 100 meters crown the day before, easily captured the 200m national title on the final day of the Jamaican Championships Sunday. World record holder Bolt posted a modest time of 20.25 seconds while running into a slight headwind. The 22-year old blazed off the curve, but eased up as soon as he hit the straight and realized he had a comfortable lead. “I ran the corner very hard because a lot of fast guys were in the race,” he said. “But when I came off the corner I looked back and just shut it down. “I was a little bit tired, but I am okay with the time.” He finished ahead of runner-up Steve Mullings (20.40) and third place Marvin Anderson (20.63). Bolt's victories qualifies him for the Berlin World Championships next month. In the women's event, Olympic champion Veronica Campbell-Brown cruised to victory in at time of 22.40. Campbell-Brown, who is recovering from a toe injury, said she is getting into shape. “I am confident that I will get in shape before Berlin.” Shelly-Ann Fraser, the Olympics 100m champion, and winner of the same event on Saturday night, returned to take second, running a impressive 22.58 out of lane two. Simone Facey was third in 22.96. In the one-lap events, Novlene Williams-Mills and Ricardo Chambers regained their national titles. Williams-Mills crossed the finish line in 50.21 ahead of Shericka Williams (50.39) and Christine Day (41.54). On the men's side, Chambers won the final straight battle with Allodin Fothergill, 45.55 to 45.57. Lansford Spance was third in 45.78. Delloreen Ennis-London took the women's 100m hurdles in 12.79 ahead of Brigitte Foster-Hylton (12.87) and Lacena Golding-Clarke (12.89). Jackson fastest in hurdles In Oregon, Olympic bronze medalist Bershawn Jackson ran the fastest 400m hurdles of the year on Sunday, then forecast an American sweep at the World Athletics Championships in August. “Most definitely a sweep,” said the head-band wearing Jackson after his victory at the US trials in 48.03 seconds. The 2004 Olympic gold medalist Shawn Crawford sped to a wind-assisted 19.73 seconds in winning the men's 200, while world champion Allyson Felix claimed the women's race in 22.02 seconds to set up another US-Jamaica sprint showdown in the Berlin world championships. Dawn Harper backed up her Beijing gold medal with a wind-assisted 12.36 seconds in the women's 100m hurdles, but there was disappointment in the heptathlon when Olympic silver medalist Hyleas Fountain withdrew after five events with a neck injury. Only the top three finishers in the cut-throat trials and defending world champions qualify for the American team for the Aug. 15-23 worlds. Young collegian Johnny Dutch claimed second behind Jackson in the 400m hurdles with a lifetime best 48.18 with Olympic champion Angelo Taylor third in 48.30. They will be joined on the US team by world champion and Olympic silver medalist Kerron Clement, who has a bye to Berlin as the defending global champion. Clement finished third in the 400 meters Saturday. World 100 meters hurdles champion Michelle Perry also took advantage of a bye and did not run the final after locking arms with hard-luck Lolo Jones in the semifinals. The collision knocked Jones out of the race and the championships. Ginnie Powell and Damu Cherry will join Harper and Perry in Berlin. Olympic silver medalist Christian Cantwell topped the men's shot put at 21.82 meters with Dan Taylor, world champion Reese Hoffa and former global winner Adam Nelson also making the team. Crawford's teammates in the men's 200 will be Charles Clark, Wallace Spearmon Jr. and Tyson Gay, who as the world champion has a bye to Berlin. Muna Lee, Marshevet Hooker and Charonda Williams will join Felix in the women's 200 at Berlin.
