Terrific race from Frerichs. She hadn't run fast this year. Now she has smashed the American record and backed up her silver medal last year. Coburn was only five seconds back, in a season best, and I don't know whether Coburn was starting too fast and dying while Frerichs ran an even pace or what, so hard to conclude that there is much of a real gap between them. Coburn thought her training had her ready to run sub 9. That will probably happen then. And you just cannot question her coaching right now, because she still ran 7 seconds under Simpson's old American record (pre-Coburn record) and she still won the gold at World's last year (she didn't just get a one year advantage from new stimuli in switching coaches--it is lasting).
