ROME — Not content with setting the best 100-meter times in the world this year, American sprinter Justin Gatlin is aiming to run even faster in Rome. The Diamond League returns to Europe Thursday, and the 100 will again be one of the highlights of the Golden Gala, the fourth event of the league. Last month, Gatlin ran the 100 in 9.87 seconds in Beijing and 9.92 in Shanghai, before running a wind-aided 9.76 in the Prefontaine Classic. “My whole motto this year is just go,” the 2004 Olympic gold medalist said. “I've got Rome now and I want to go even faster.” Gatlin edged Usain Bolt on the line by 0.01 seconds last season. Bolt, the world and Olympic champion, will not be at Stadio Olimpico this year, but the likes of former world champ Kim Collins, Jamaicans Nesta Carter and Kemar Bailey Cole, and world indoor 60 champion Richard Kilty will be aiming to take Gatlin's title. In the women's event, Shelly-Ann Fraser-Pryce will be looking to bounce back from a disappointing 200 in Eugene, where she finished last. Fraser-Pryce is the most titled sprinter in history in the 100, with two Olympic gold medals and two world titles. — AP
