Can Lyles dip under 9.80? Can Timothy Cheruiyot break 3:30 for the second time in 8 days? Plus we tell you why Michael Saruni didn't race for 5 months after running 1:43 indoors.

History very well may repeat itself in the men's 800 this year. But will it be David Rudisha winning again in London or might it be an upstart NCAA freshman star winning a global title? And don't sleep on Nijel Amos.

The greatest 800 runner ever is our pick for #1 again. There are two Americans in the top 10, but where do Murphy and World Indoor champ Boris Berian rank against the world's best?

Paul Chelimo headlines the men's 3,000 field, which includes fellow Olympic silver medallist Paul Tanui plus Ryan Hill, Hagos Gebrhiwet, Muktar Edris and Yomif Kejelcha. Olympic champ Faith Kipyegon could be capable of something really fast in the 1500 as she faces Jenny Simpson and Shannon Rowbury, while Ruth Jebet, Hyvin Kiyeng and Emma Coburn renew acquaintances in the steeple. Plus Berian vs. Souleiman vs. Bosse vs. Makhloufi in the 800.

No man has repeated in the 800 at the Olympics since New Zealand's Peter Snell in 1960 & 1964. Defending world champ Rudisha enters as the world leader and favorite, but he'll be challenged by Kenyan Trials champ Alfred Kipketer, 2015 Worlds runner-up Adam Kszczot, France's Pierre-Ambroise Bosse and many more.

The last Diamond League meet before a month long break features some great mid-d events. In the men's 800, Rudisha faces Pierre-Ambroise Bosse, Ferguson Cheruiyot and Adam Kszczot while Dawit Seyaum is entered in the women's 1500 against Laura Muir and Hellen Obiri. Plus Keni Harrison (100H), Christian Taylor (TJ), Renaud Lavillenie vs. Shawn Barber (PV) & Brittney Reese vs. Tianna Bartoletta (LJ).

That puts her #3 in the world this year only behind Caster Semenya and Francine Niyonsaba. Nicholas Kipkoech won the 800 in 1:43.85 with Pierre-Ambroise Bosse 3rd (1:44.53). France's Jimmy Vicaut equaled European 100m record with 9.96

Rudisha is back but beatable, Farah now owns all the British records, the 800m is a different event this year, and Caterine Ibarguen's 38 win streak in the triple jump came to an end.

The first-ever DL meet in Africa didn't disappoint.

Erik Sowinski was 4th (1:47.39). Augustine Choge ran 7:43 to win a close 3000 over a good field including Yomif Kejelcha, Caleb Ndiku and Yenew Alamriew. In the jumps, Renaud Lavillenie jumped through a painful ankle to beat Shawn Barber with 5.91m. Cuba's Alexis Copello set a TJ WL at 16.99m.

Choge won over Caleb Ndiku (2nd - 7:39.82), Yenew Alamriew (3rd) as well as many other top African stars. Elijah Manangoi won the 1500 (3:39.77) as Adam Kszczot ran 1:46.00 to win the 800 over Pierre-Ambroise Bosse and Eric Sowinski. Habitam Alemu won the women's 800 (2:01.99). *Full Results *Meet Videos

David Rudisha lost the most races of his pro career this year but he's our #1. We tell you why. How could we possibly rank Boris Berian as the US #1 when he didn't even make the final at USAs? Because Nick Symmonds told us to.

A big surprise came in the men's 800 where Italy's Giordano Benedetti got the win in 1:45.11 over favorites Pierre-Ambroise Bosse of France and Adam Kszczot of Poland.
