Olympic champion hurdler Dayron Robles made it four wins from four races this season at the Aviva Grand Prix Saturday, while injury-hit Christian Olsson won his first triple jump competition for three years. Although beaten out of the blocks by Dutch hurdler Gregory Sedoc, Robles pulled away from the field to cruise to victory in 7.44 seconds. Petr Svoboda of the Czech Republic took second in 7.57. “That was very good for me today,” the Cuban said. “I am getting better and better with every race and feeling very confident. I'm sure there is more to come. It's looking good.” Hampered by a foot injury after the 2004 Olympics, Olsson has taken a long time to come back after having considered retirement. Against a high-quality field, however, he took the lead in the third round with a leap of 17.32 meters. His only other legal leap in the competition was 16.97 in round two, but his best was enough to beat Yoandri Betanzos of Cuba by two centimeters. “I'm really happy with that performance; 17.32 is my longest jump in all my injuries,” said Olsson, whose best was a world-record equaling 17.83 at the 2004 indoor worlds. With athletes warming up for the indoor worlds in Doha next month, American sprinter Carmelita Jeter edged rival Laverne Jones in the 60 meters despite both clocking 7.06. Jones, from the US Virgin Islands, was quicker out of the blocks and led virtually until Jeter got up on the the line. “I'm still working out some kinks but it was a great run,” the American said. “Last year, my personal best was 7.11.” Tirunesh Dibaba, the Olympic 5,000- and 10,000-meter champion, ran the second fastest indoor two miles ever in a thrilling victory over Kenya's Vivian Cheruiyot and Ethiopian countrywoman Sentayehu Ejigu. With the lead changing twice over the closing four laps, Dibaba hit the front chased by Ejigu. She then had to hold off a late charge by Cheruiyot and finished in 9 minutes, 12.23 seconds. Cheruiyot was 0.12 behind. The fastest ever two miles by a woman is 9:06.26 by Meseret Defar of Ethiopia in Prague a year ago.
