Coin toss for an Olympic spot? Felix, Tarmoh in dead heat
The scenarios involve either a coin toss or a runoff to decide which athlete will earn the third and final spot on the team for the London Games.
If both athletes choose the same option, it will determine the tiebreaker. If the athletes disagree, the tiebreaker will be a runoff. If both athletes decline a preference, the tiebreaker will be a coin toss.
Bobby Kersee, the coach for both athletes, told The Associated Press the sprinters won't make any kind of decision until after they complete the 200 later this week.
Being the coach of both, Kersee said he had a conflict of interest in this situation and just wanted to do right by his runners.
The USATF said in a release that two cameras are used to determine photo-finishes, one on the outside of the track and another on the inside.
In Saturday's race, the image from the outside camera was inconclusive for determining the finish because both runners' arms obscured their torsos.
The torso position is used to determine the finish.
The Cheap Oakleys from the inside camera, shot at 3,000 frames per second, was analyzed by timers and referees, who declared the tie.
Tarmoh, 22, would be in line to claim her first ever Olympic spot. Felix has won Olympic relay gold to go along with two silvers in the 200.
Both are entered in next week's 200 at the trials, with Felix having made the decision to forego the 400 for the 100.
Carmelita Jeter won the race, with Tianna Madison also booking her place for London.
