If Cooper Lutkenhaus isn't already on your radar, it's probably because he's too fast to catch. The 17-year-old American edged Olympic champion Emmanuel Wanyonyi by one-hundredth of a second in the 800-meter Diamond League competition in Oslo on Thursday, clocking 1:42.08—his personal best and the fastest time in the world this year—and sealing it with a headlong dive at the finish. The pair blasted through halfway in under 50 seconds before Lutkenhaus surged clear with 200 meters to go; the Kenyan clawed back ground but ran out of track. "To beat the Olympic champion is awesome," Lutkenhaus told the Guardian, adding that the dive left grazes he'd feel later.
Wanyonyi, fresh off the birth of his daughter, even sounded impressed: "This boy is in good shape," the 21-year-old said. Lutkenhaus brushed aside talk he's now No. 1, saying one win doesn't make him better than the Olympic champion. But the teen is on a roll, winning the world indoor title in March and debuting as the Diamond League's youngest ever winner last weekend, per the BBC. He's now undefeated in his last six 800-meter finals. "Every time I think I've reached a limit, I feel like I'm able to break it the next race I run," he said. The meet offered a reality check for another teenage standout, 18-year-old Australian sprinter Gout Gout, who finished sixth in his first senior 200-meter Diamond League race as Olympic champion Letsile Tebogo warned him not to rush his progression.
