MIRAMAR, Fla. -- Even if track and field fans weren't starved for high-level competition in the last year, Saturday's Miramar Invitational at the Ansin Sports Complex in Florida would have them salivating at the incredible array of talent set to compete on the second leg of the USATF Journey to Gold - Tokyo Outdoor Series. The event is a World Athletics Continental Tour Silver Label meet and features possibly the strongest outdoor collection of the sport's luminaries thus far this year. Watch the Miramar Invitational live Saturday, April 10 starting at 1 p.m. ET on USATF.TV+ in the U.S. and Canada. Any talk of athletes with a hot hand begins with Team USATF's Grant Holloway (Chesapeake, Va.), who is making his '21 outdoor debut in the 110m hurdles after blitzing the world indoor 60mH scene on an undefeated slate of races that saw him break one of the oldest world indoor records, clocking 7.29 at Madrid. Holloway was the 2019 World champion in the 110mH and set a collegiate record and PR of 12.98, but former SEC rival Daniel Roberts (Atlanta, Ga.) handed him a loss at the 2019 Toyota USATF Outdoor Championships in Des Moines. Roberts is returning to the outdoor track for the first time since 2019 and will look to challenge Holloway for the win. Not to be outdone, the women's sprint hurdles will showcase world record-holder Keni Harrison (Claytom, N.C.), who was the silver medalist at the last World Championships. She faces British duo Tiffany Porter, a three-time World Indoors 60mH medalist, and Cindy Sember, who was fourth at Rio in 2016, along with Olympic sixth-placer Pedrya Seymour of the Bahamas and American Payton Chadwick (Springdale, Ark.), who enjoyed a successful overseas swing last September that included wins at Zagreb and Doha. Ageless wonder Justin Gatlin (Brooklyn, N.Y.), the 39-year-old who won world gold in 2017 and silver in 2019, is one of nine entrants who sport sub-10 personal bests in the men's 100m, and the women's field is equally as impressive as seven of them have dipped under 11 seconds. Sha'Carri Richardson (Dallas, Texas), will line up against Rio 4x100m relay gold medalist English Gardner (Vorhees, N.J.) and 2018 USATF indoor 60m winner Javianne Oliver (Monroe, Ga.), as well as Doha 4x100m bronze medalist Dezerea Bryant (Milwaukee, Wis.), who was also fifth in the 200m. Double the distance brings double the excitement, with Jamaica's double Rio gold medalist Elaine Thompson-Herah topping the women's 200m field. She will have her hands full with Doha silver medalist and reigning USATF champion Brittany Brown (Upland, Calif.), plus the duo of 2015 Pan American Games silver medalist and former collegiate record holder Kyra Jefferson (Detroit, Mich.) and Olympic veteran Jenna Prandini (Clovis, Calif.). Youngsters Candace Hill (Conyers, Ga.), the fastest U18 100m runner ever, and Jamaica's double world U20 sprint champion Briana Williams are the emerging stars. Reigning Olympic 1500m gold medalist Matthew Centrowitz (Beltsville, Md.) drops down to run the men's 800m, where his 1:44.62 PR puts him in good stead against much-traveled Erik Sowinski (Waukesha, Wis.), one of the most consistently good half milers on the international scene. Olympic and World Championships semifinalist Robby Andrews (Manalapin Township, N.J.) is another man to watch. American record holder and two-time World Championships bronze medalist Ajee' Wilson (Neptune, N.J.) has already run sub-1:59 this year and will again match up in the women's 800m with Jamaica's Natoya Goule, a 1:56.15 performer. Wilson and Goule have run against each other more than 20 times since 2014, and the only time Goule beat Wilson was when she set that PR at Monaco in 2018. Ce'Aira Brown (Philadelphia, Pa.), eighth at Doha, and 2017 World Championships seventh-placer Charlene Lipsey (Hempstead, N.Y.) are also sub-2:00 performers in the field. Both long jumps feature defending global champions. Reigning Olympic gold medalist Tianna Bartoletta (Elyria, Ohio) has been among the crème de la crème of the women's event since she won her first world title at Helsinki in 2005. Malaina Payton (Vallejo, Calif.) set a lifetime best last weekend in California to move up among the world leaders in 2021, and Britain's Lorraine Ugen won NCAA indoor and outdoor gold when she was at TCU. France's Yanis David was the 2019 NCAA outdoor winner. A big winner at Doha in 2019, Jamaica's Tajay Gayle leads the men's long jump field. Gayle jumped well in limited action last summer and if he is anywhere near the form that carried him to global gold two years ago it will be tough for Americans Marquise Goodwin (Garland, Texas) and Marquis Dendy (Middletown, Del.) to topple him. Goodwin has had a few years away from the sport playing in the NFL, but showed he is still to be reckoned with following an 8.12m/26-7.75 last week in his first competition since 2016. Dendy is also a comeback story after injuries hampered him the last couple years, and he would love to be back in the form that made him the world indoor gold medalist in 2016. Relative newcomer Kenny Bednarek (Rice Lake, Wis.) at 19.80 is the fastest man in the field in the men's 200m, but an interesting foe comes in the form of Doha 400m bronze medalist Fred Kerley (Morgan City, La.), who lowered his lifetime best in the 100m to 10.03 last week and seems due for a sub-20 effort over half a lap. Another youngster with Olympic aspirations heads the men's 400m field, as Justin Robinson (St. Louis, Mo.) hopes to pick up right where he left off last year. Robinson, still just 19, led the world list for one lap at 44.91 last season, and was the 2019 Pan American Games bronze medalist. Doha 4x400m gold medal teammates Wil London (Waco, Texas) and Michael Cherry (Chesapeake, Va.) have the speed and experience to take the top spot, as does 2018 U.S. and 2019 NCAA outdoor champ Kahmari Montgomery (Plainfield, Ill.). Perhaps better known as a 400m hurdler, Quincy Hall (Kansas City, Mo.) is also speedy without 10 barriers in his path, bringing a 44.53 lifetime best into this meet. This year's fastest woman, Shamier Little (Louisville, Kentucky), has clocked 50.19 and is favored against five-time Olympic and World finalist Stephenie McPherson of Jamaica. Quanera Hayes (Hope Mills, N.C.) has won three world indoor and outdoor 4x400m golds and has improved her short speed recently. Four of Team USATF's best women in the shot put will go up against Doha silver medalist Danniel Thomas-Dodd of Jamaica. Maggie Ewen (St. Francis, Minn.) was fourth at Doha in 2019 and won NCAA gold in three throwing events during her collegiate career, while three-time U.S. champ Chase Ealey (Los Alamos, N.M.) has emerged as a medal contender and was seventh at Doha. Explosive Raven Saunders (Charleston, S.C.), fifth at the Rio Games and the 2017 USATF outdoor champion, and 2019 Pan American Games bronze medalist Jessica Ramsey (Boynton Beach, Fla.) give the field superb depth, and this looks to be a great preview of the Olympic Trials for the American quartet. Other top names to keep an eye on are Kenny Selmon (Mableton, Ga.), this week's USATF Athlete of the Week after clocking a world-leading 48.87 in the men's 400m hurdles at the USATF Sprint Summit in Prairie View, and high jumpers Trey Culver (Lubbock, Texas) Jeron Robinson (Angleton, Texas) and Ty Butts-Townsend (Alexandria, Va.). Culver has the highest clearance by an American man this year at 2.33m/7-7.75 and Robinson is a three-time USATF champion. Butts-Townsend was eighth in the women's high jump at Doha in 2019.
