Men's 800 features Duane Solomon, Brandon Johnson, former NCAA champ Edward Kemboi, Lopez Lomong, Ryan Martin, Eliud Rutto and David Torrence while the women's has Roesler, Molly Ludlow, Oregon's Raevyn Rogers, former NCAA 1500 champ Shelby Houlihan. Vashti Cunningham makes her pro debut in the HJ, Allyson Felix highlights the sprints.

The biggest news was Mo Farah pulling out of the meet before hand, but on the track there was a thrilling women's 200m, in the infield one of the best javelins ever, and in the distances Hassan and Amos picked up their first DL wins of the year and Bernard Lagat another master's WR in one of his least impressive runs of the year.

Bolt vs Gatlin didn't happen but there was still drama in the 4x100, a disaster in the 4x200, and an apology from Tyson Gay.

Allen ran a slightly wind-aided 13.16 to beat defending champ Ryan Wilson by .005; David Oliver was 3rd. Jeneba Tarmoh (you remember her from the 2012 dead heat fiasco) won the 200 (22.06) as Curtis Mitchell ran 20.13 to beat Wallace Spearmon (20.19). Inika Mcpherson gets HJ title in 2.00m PR (previous best 1.96m) beating Chaunte Lowe and Brigetta Barrett. Kori Karter takes 400H as Johnny Dutch wins for the men (48.93). Sam Kendricks the PV (5.75), Jeffery Henderson the LJ, Gia Lewis-Smallwood the discus and Sean Furey the javelin.

The team of Tianna Bartoletta, Alexandra Anderson, Jeneba Tarmoh and Lekeisha Lawson ran 41.88 to beat Jamaica's 42.28.
