Kristin Castlin says the slight of being placed on the far outside lane was all the motivation she needed to snap Brianna Rollins' 19-race win streak in the 100 meter hurdles.
Castlin edged fellow American Rollins with a time of 12.571 to win the race on the second day of the Drake Relays Saturday.
"I had a little bit of a chip on my shoulder being in lane eight," said Castlin. "I had to execute my best race since I was out there on my own."
Rollins finished second in 12.576, halting a win streak that dated back the 2012 Olympic Trials.
"I was surprised. This was my first race of the season," said Castlin.
Rollins, who plans to runs next week in Jamaica, said she wasn't thinking about the streak.
"This was a great opener," Rollins said. "I just wanted to run a relaxed race and tried to focus on myself.
"Someone else beat me to the line but that's okay."
France's Renaud Lavillenie won the men's pole vault by clearing 5.70 metres at Drake Stadium. Steve Lewis matched his height but finished second because of more misses.
Mark Hollis finished third, soaring to 5.60 metres.
"I'm happy with this victory, because I managed some good jumps," Lavillenie said. "I took this contest as a challenge. It gives me confidence."
American Tiffany Ross Williams won the women's 400 metre hurdles with a time of 55.53 seconds while Chaunte Lowe took the women's high jump by clearing 1.96 metres.
