Athing Mu delivered an American record gold medal performance on the biggest stage possible while fellow 19 year-old Keely Hodgkinson got silver and American Raevyn Rogers PRd for bronze.

For the third year in a row, Caster Semenya was undefeated but was this the last of her dominance?  Domestically, Ajee Wilson was the best of a strong group of US runners. Should US#3 Ce'Aira Brown be ranked in the world's top 10?

Can Ajee Wilson get the elusive gold medal? How does Raevyn Rogers do? Does Niyonsaba stay undefeated lifetime indoors?

Boston is the PLACE TO BE this weekend as there are some great names entered in these two events. From sprint stars like Wayde van Niekerk, Yohan Blake, Toriw Bowie, and  Shaunae Miller-Uibo to mid-d and distance stars like Robby Andrews, Leo Manzano, Donavan Brazier, Dejen Gebremeskel, and Muktar Edris. Plus can HSer Casey Clinger break 4:00 in the mile?

Chanelle Price shocked the world with her gold medal two years ago in Sopot. Can Wilson come through as the favorite on home soil in Portland?
