PRAIRIE VIEW -- Strong fields in the men’s pole vault and women’s 400m and 100m hurdles top the card for Tuesday’s USATF Invitational, the ninth stop on the USATF Journey to Gold - Tokyo Outdoor Track & Field Series. The meet is also a World Continental Tour Silver event. UPDATE: Live webcast unavailable due to weather. Check back for on-demand. World leader Chris Nilsen takes on the collegiate indoor and outdoor record-holder KC Lightfoot who enters his second meet as a professional. Nilsen set the 2021 world outdoor lead of 5.91m/19-4.75 at the USATF Golden Games presented by Xfinity and Lightfoot is tied for the fourth best outdoor vault of the year at 5.80m/19-0.25 after an indoor campaign that saw him join the six-meter club. On the women’s side, Olivia Gruver enters with top clearance in the field at 4.70m/15-5, equal to the fifth best in the world this year. Three-time Olympic gold medalist Tianna Bartoletta returns to the long jump after her April 23rd winning leap of 6.20m/20-4.25 at the Oregon Relays. Sha’Keela Saunders enters with the best mark in the field, a 6.64m/21-9.5 leap. Likely the most loaded field in the meet, the women’s 400m has a world champion, a world record holder in the hurdles, the fourth place finisher at Doha in 2019, and a nine-time Olympic world and world indoor relay gold medalist to go along with the most recent Diamond League winner. Phyllis Francis won the 400m World Championships gold in 2017 and added golds at the Rio Games and the last two Worlds in the 4x400m relay. She placed fifth at Doha in the open 400m. World champion and world 400m hurdles record holder Dalilah Muhammad is also a force without the barriers as evidenced by her 50.60 PR. Veteran Natasha Hastings is one of the most decorated relay runners in U.S. history and was fourth at Rio in 2016 in the 400m. In the men’s 400m, 2016 Olympian in the 400m and 4x400 Gil Roberts highlights the field. Roberts garnered a gold on the U.S. 4x400m squad at Rio and owns a best of 44.22 among his 21 lifetime races under 45 seconds. Reigning national indoor 60m champion Mikiah Brisco won the USATF Open at Fort Worth last week, battling a hefty headwind to clock 11.42. The 2017 NCAA 100m champion for LSU, Brisco will see a familiar old Southeastern Conference foe in Kiara Parker, the former Arkansas star who picked up a World Championships 4x100 bronze at Doha. Parker zipped to an 11.07 Sunday in Boston to win the “B” section. Doing double duty is long jumper Tianna Bartoletta, who was fourth in the 100m at London in 2012 before running the opening leg on Team USATF’s stunning world record 40.82 4x100m relay. Four times a World Championships 100m representative for Team USATF, Mike Rodgers ran the third leg on the American record-setting 4x100 at Doha. He has a 100m best of 10.12 this year and leads men’s dash entries. As expected in an event that is dominated on the world scene by Americans, the women’s 100m hurdles will showcase several of the best in history. Rio bronze medalist Kristi Castlin has run 12.50 in her career, while Dawn Harper-Nelson won gold at the 2008 Olympics and added silver in 2012 at London with a 12.37 PR effort. 2015 Pan American Games gold medalist Queen Claye was third at Fort Worth last week and has a lifetime best of 12.43. Donald Scott enters the men’s triple jump as the fifth ranked leaper in the world following first and second place finishes on the World Athletics Continental Gold Tour at the USATF Grand Prix and USATF Golden Games. Scott has five U.S. titles to his credit and was sixth at Doha in 2019. In the women’s high jump, Rachel McCoy looks to build on her 1.93m/6-4 performance in Tucson on May 22 which tied her personal best. Doha women’s 4x100 bronze medalist Teahna Daniels and 2018 NCAA indoor men’s 200m champion Elijah Hall are two of the top Americans in the 200m.
