1 Molly Huddle Saucony 15:10.01
2 Amy Hastings Brooks 15:14.31
3 Angela Bizzarri Brooks 15:16.04
4 Jennifer Rhines adidas 15:19.12
So if I am reading the USATF guidelines correctly (only runners in the top 4 of Nationals can go) the USA team will consist of one A runner and one B runner (i.e. AB).
If either Hastings or Bizzarri had run the A standard then it would have been an AAB team going.
So it looks like Huddle and Hastings are the team.
USATF could send a full team if they chose to but that would be against their own guidelines. Perhaps they should expand on the number of "time chasers" in the future or give themselves some kind of loophole to add a runner that performs some type of A+ performance when the team is not full.
