Jonah Koech wasn't even supposed to be in Sunday's 1500. As they approached the bell, he was in 13th out of 17. A lap later, he was the champion. He is just the third American man to win a Diamond League 1500/mile and the first runner sponsored by Under Armour to win a DL race. His 3:37.27 pre-race pb is also the slowest of any man to win a DL 1500/mile.
