10. Noah Lyles proves 100m dominance, turns pro
Was there a more ubiquitous face at the U20 Championships than that of Noah Lyles? The 19-year-old 200m national record holder stole the show in the 100m final by clocking 10.17 (+0.2) over runner-up Filippo Tortu of Italy's 10.24. Lyles later led Team USA with the same dominance in the 4x100m relay. He received the baton from Brandon Taylor just behind Team Japan, but quickly made up the deficit and blasted through the line in 38.93 as Japan ran 39.01.
The biggest non-Poland-specific news to break during the championships was his decision to forego his scholarship to the University of Florida in favor of signing an eight-year professional contract with adidas. He made the announcement late on Friday night via Twitter along with his brother, Josephus; they chose that date because it was Josephus' 18th birthday.
