Joan Benoit Samuelson night at Pre looks fantastic as a couple of world record holders (Ruth Jebet and Genzebe Dibaba) will be racing as will a couple of American record holder (Emma Coburn and Molly Huddle). Might some WRs and ARs fall?

Ajee Wilson, Alysia Montano and Brenda Martinez have all starred on the international stage before. Will they make it to Rio? Not necessarily, as 12 Americans this year have run between 1:59.72 and 2:00.82.

Six weeks from the Olympic Trials and a lot of things are still up in the air. Will Leo Manzano put it together in time in the 1500? Can Andrew Wheating stay healthy? Will Laura Roesler or Brenda Martinez wind up missing out in the uber-competitive women's 800? We'll start to get some answers on Friday at Oxy, which also features Robby Andrews, Shannon Rowbury, Emma Coburn and Eric Jenkins in their outdoor openers, plus Evan Jager in the steeple. *MB: Official 2016 Hoka One One Oxy Live Discussion Thread

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.

Wilson had the lead early, but she wasn't ready for an aggressive move at the halfway point by Niyonsaba, who claimed her first global medal. Kenya's Margaret Wambui was third and the U.S.'s Laura Roesler fourth.

The women's 800 was the lone distance event in the Saturday morning session, but there was excitement for American fans as both Wilson and Roesler came away with heat victories.

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?

Laura Roesler (800) and Cory McGee (1500) also made it onto Team USA but men's 800 runner-up Erik Sowinski will have to wait to see if he'll get an at-large bid from the IAAF for World Indoors.

Laura Roesler and Ajee Wilson both faced some trouble in their prelims but ultimately advanced to Saturday's final unscathed. Boris Berian and Erik Sowinski had an easier time of it on the men's side.

Wilson, Roesler and Treniere Moser are the only women with the IAAF standard, so two of those three women will be your team for World Indoors.

Millrose is the jewel of the US indoor season for a reason.

Hunter would join Alan Webb as the only two high schoolers to go sub-4 indoors. Chris O'Hare and Cristian Soratos are also in the mile, Jordan Hasay, Nicole Tully and Emma Bates are in the 3000, Ajee Wilson, Morgan Uceny and Laura Roesler in the 800 with Robby Andrews in the men's 800.

What a week. In the WTW, we give Ryan Hall some more praise, introduce you to Sammy Wanjiru's wife, who just ran one of the greatest races ever on US soil, tell you why Jenny Simpson's and Matthew Centrowitz's gold medal dreams just took a hit, and break down the fast and slow half marathons for Puskedra and Estrada.

Mark Wetmore's two biggest stars will make their season debuts - Jenny Simpson (800) and Emma Coburn (1,500) - while Kara Goucher (5,000) will run her first track race since 2013 and Mary Cain will look to regain her "teen phenom" label.

Ajee Wilson, Laura Roesler, Mary Cain and Natoya Goule are all entered in the women's 800. Rupp & Levins will attempt the mile/2 mile double with less than 30 minutes rest and new pros Abbey D'Agostino and Marielle Hall will face Jordan Hasay in the women's 2 mile. The meet concludes with a WR attempt in the DMR (Team USA features Matthew Centrowitz, Mike Berry, Erik Sowinski and Pat Casey).
