Young American discus thrower Sam Mattis took the world lead with an amazing 67.45m. At Philadelphia College Classic, Sam had an amazing series - 67.45, 63.28, x, x, 66.51 and 67.21.

His previous PB was 62.48m from season 2015. That means he improved PB 4m and 97cm. It is a rare occiasion on that high level to improve so many meters. Only 7 discus throwers in the history have improved their PB more 5m during a competition. For example, Mike Hoffman improved his PB from 58.70m to 65.84m in 1971 in Lancaster California (7.14m improvement).
