HS Boys 400m Elite -- Justin Robinson 44.84 Jun 8, 2019

Justin Robinson was waiting for the right time. And Saturday proved to be the perfect moment for the Hazelwood West (MO) High School junior. Robinson was absolutely incredible over 400 meters at The Great Southwest Classic, clocking a No. 2 all-time high school mark of 44.84 seconds, which solidified a new meet record and put Robinson, the New Balance Nationals Indoor champion at the distance, into the driver's seat toward a potential new national record. "I was just trying to hold on for the last 10 meters and finish things strong," he said. "I really didn't know how fast I ran until I passed the finish line." Robinson bypassed 45 seconds entirely, going from a previous outdoor personal best of 46.20 seconds to 44.84. His previous best 400m times in 2019 were 46.22 and 46.30.  In the process, he moved ahead of Jamal Walton, who became the second high school boy to go under 45 seconds in 2017 while competing for the Cayman Islands. He ran 44.99 seconds at the Pan-American Junior Athletics Championships. Robinson only stands behind Darrell Robinson, who scored the national record of 44.69 seconds in 1982. 

HS Girls Elite100 -- Briana Williams 11.02 Jun 8, 2019

Briana Williams is fast closing in on Candace Hill, and quickly moving up the Jamaican ranks.  The Oakland Park Northeast (FL) High School junior pocketed the No. 2 all-time high school effort and a new Jamaican U20 record at 100 meters on Saturday, going a wind-legal 11.02 (+0.8) seconds at The Great Southwest Classic. This came directly off a performance last weekend in Jacksonville, where Williams ran a wind-legal 11.10 seconds against top-level competition. She remains the No. 2 athlete at the distance all-time among American high school ranks and moves into sole possession of the No. 2 time in history, ahead of Kaylin Whitney's 11.10. While Williams' effort on Saturday was at altitude -- over 5,000-feet elevation -- it was directly in line with where her coach, Ato Boldon, suspected her ability could take her at this point in the season. And her season isn't finished. A few marquee meets, including qualifiers for the Jamaican Senior team, remain ahead of the World Championships. Hill was the last -- and remains the only -- high school girl to break 11 seconds in 2015. She did so at a national meet, scoring a time of 10.98 seconds at Brooks PR. It wasn't long before Hill, currently with Asics, turned pro soon after -- well before her high school graduation -- and jumpstarted her professional career. Williams, inarguably more accomplished than Hill at the same juncture -- in 2018 she won two golds at the IAAF U20 Championships in Finland and seems primed to represent Jamaica at the senior level -- is headed toward that direction.
