MIRAMAR, Fla. -- The fastest early-season women’s 100m performance in history brought the large crowd at the inaugural Miramar Invite at Ansin Sports Complex to its feet, and was only one of many impressive efforts on the second stop of the USATF Journey to Gold - Tokyo Outdoor Series, a World Athletics Continental Tour Silver Label meet. Sha’Carri Richardson (Dallas, Texas) didn’t get the best start, but she showed incredible top-end speed to blast a jaw-dropping 10.72 and move to No. 6 on the all-time world performer list and No. 4 on the all-time U.S. performer list. Only world record holder Florence Griffith-Joyner, Carmelita Jeter and Marion Jones have ever run faster as Americans, and no woman has ever run faster as early as the month of April. A fantastic matchup in the women’s 400m produced the fastest time in the world for Shamier Little (Louisville, Ky.), but it didn’t come easy. Little, best known previously as a 400m hurdler, was on the inside of Quanera Hayes (Hope Mills, N.C.) and was chasing Hayes for much of the race. In the closing stages Little powered through and had just enough to edge Hayes 49.91 to 49.92. It was a lifetime best for Little, and Hayes clocked her best time since 2017. In the men’s 100m, Kyree King (Ontario, Calif.), a 2017 World Championships 200m semi-finalist, broke into the sub-10 club, winning in a lifetime best 9.97 over 2017 world champion and 2019 World Championships silver medalist Justin Gatlin (Brooklyn, N.Y.), who closed well to clock 9.98. World record holder Keni Harrison (Clayton, N.C.) was pushed by an illegal breeze in the women’s 100m hurdles, but was impressive nonetheless with a 12.38w aided by 2.7 mps wind. Harrison was solid out of the blocks and kept her poise through the race, backing up the 12.54 world-leading time she put up in the heats. British sisters Cindy Sember and Tiffany Porter went 2-3 in 12.55w and 12.57w, while heptathlete Taliyah Brooks (Wichita Falls, Texas), who shattered her lifetime best with a 12.70 in the heats, was fourth in 12.75w. Unchallenged from the gun, Grant Holloway (Chesapeake, Va.) won the men’s 110m hurdles in 13.04w (+2.2 mps), showing he hasn’t lost anything from the form that carried him to a world indoor record in the 60m hurdles in February. Holloway didn’t touch any of the 10 barriers and looked comfortable as he stamped his early claim to the role as Tokyo favorite. 2019 U.S. champion Daniel Roberts was second in 13.30w. Last week’s USATF Athlete of the Week, Kenny Selmon (Mableton, Ga.), took a two-stride lead through the first half of the men’s 400m hurdles and held that lead despite clipping the eighth barrier, sprinting on to lower his own world-leading performance with a 48.81. Craig Allen (Carrollton, Ga.) outleaned Amere Lattin (Missouri City, Texas) by .01 for the runner-up spot in 49.70. Upsetting reigning Olympic champion Elaine Thompson-Herah of Jamaica in the women’s 200m, Jenna Prandini (Clovis, Calif.) drove out of the blocks and controlled the race all the way to win in 22.29w, aided by a 2.2 mps wind. 2019 World Championships silver medalist Brittany Brown was second in 22.39, with Candace Hill (Conyers, Ga.) clocking her fastest time since 2016 in third at 22.43. A massive 4.0 mps wind pushed Kenny Bednarek (Rice Lake, Wis.) to a 19.65 win in the men’s 200m, well clear of runner-up Emmanuel Matadi of Liberia, who was second in 20.20. Fresh out of high school, 2019 Pan American Games bronze medalist Justin Robinson (St. Louis, Mo.) took down some of the top one-lap runners in the U.S., fighting off Kahmari Montgomery and Wil London to win the men’s 400m in 45.23. Montgomery was the leader down the backstretch into the teeth of a strong wind, and he and London were side-by-side coming off the last bend. Robinson moved up on their inside and went ahead with about 10m remaining, while London took second in 45.31. Traditionally a frontrunner, Jamaica’s Natoya Goule went to the lead in the women’s 800m and was in prime position with 150m to go when Ajee’ Wilson (Neptune, N.J.), the fastest woman in the world outdoors in 2021, pulled up on her shoulder and moved past her in the last half of the final straight to win in 2:00.57. Kameron Jones (San Diego, Calif.), the 600m bronze medalist at the 2019 USATF Indoor Championships, led the men’s 800m field through the first 400m in just over 53 seconds, trailed by Jamaican Rajay Hamilton and 2019 USATF Indoors bronze medalist Abraham Alvarado (Winston, Calif.). Jones stayed at the front for 799m, but Alvarado lunged past him at the line to win in 1:47.29, .04 ahead of Jones. Clearing her best height since 2016, Rachel McCoy (Fontana, Calif.) sailed over 1.90m/6-2.75 on her third attempt to win the women’s high jump. Last year’s Toyota USATF Indoor Championships runner-up Shelby McEwen (Abbeville, Miss.) was the men’s winner as the only person to clear 2.26m/7-5. Reigning world champion Tajay Gayle of Jamaica recorded the best outdoor long jump in 2021, winning with his 8.27m/27-1.75 in round two. Holland Martin of the Bahamas was second, with Damarcus Simpson (Lafayette, Ga.) the top American, placing third at 8.05m/26-5w. Canada’s Christabel Nettey, fourth at the 2015 World Championships, had her best effort of the day in round three to win the women’s long jump with a windy 6.63m/21-9 leap. Sha’Keela Saunders (Elizabeth City, N.C.) was second with a windy best of 6.57m/21-6.75, getting the nod over Taliyah Brooks (Wichita Falls, Texas) based on a better secondary mark. Silver medalist at Doha in the 2019 World Championships, Jamaica’s Danniel Thomas-Dodd uncorked a 19.17m/62-10.75 in round three to win the women’s shot put ahead of Americans Maggie Ewen (St. Francis, Minn.) and Jessica Ramsey (Boynton Beach, Fla.). Ewen’s 18.69m/61-4 is the best by an American outdoors this season, and Ramsey nabbed bronze with an 18.61m/61-0.75 on her final throw. Kenya’s Michael Saruni, best known as an 800m runner with a 1:43.25 PR, used his speed over the final 50m to win the men’s 1,500m in 3:45.84. Battling strong winds, the pack followed the pacemaker through the first three laps at medium pace before Nanami Arai of Japan sprinted to the lead coming into the final stretch. At that point, Saruni went wide and sped past Arai for the victory. Full results from today’s Miramar Invitational can be found here.
