Sean McGorty almost lost a shoe but didn't panic and advanced while Chris Nilsen pulled off another upset in the pole vault and Will Claye was clutch in the triple jump.

Christian Taylor gave some love to OBJ.

Taylor became the first man in 36 years to defend his Olympic triple jump title and now owns more global triple jump golds than any man in history. He's now in the conversation for the GOAT along with world record holder Jonathan Edwards and three-time Olympic champ Viktor Saneyev.

The best shot for a South American to win T&F gold in the first Olympics on South American soil comes in the women's triple jump, where there are not one, but two candidates. Ibarguen has won 36 of her 37 competitions since taking silver four years ago, while Venezuela's 20-year-old World Indoor champ Yulimar Rojas has improved markedly in 2016 and should push Ibarguen.

Team USA has struggled at these championships but Thursday night went very well for the Americans as Taylor (triple jump) and Felix (400) earned the U.S.'s 2nd and 3rd golds of the championships in impressive fashion -- an 18.21 jump (#2 all-time) by Taylor and a 49.26-second run for Felix (PB). Justin Gatlin couldn't complete a perfect night, which is understandable as he once again lost to the incomparable Usain Bolt (19.55 to 19.74) and had to settle for silver.

Running in his first race since the NOP doping investigation became public, Mo Farah celebrated his win as if he'd won a World title while Nijel Amos won a big battle in the men's 800 but limped off the track injured.
