LOS ANGELES — As track and field athletes from around the world gear up for the USATF Los Angeles Grand Prix, below is an event-by-event preview. 100m: One week later and 3,000 miles to the West, Christian Coleman continues his quest for sprint supremacy after a wind-blown 9.78w at the USATF Bermuda Grand Prix gave him his first 100m win of the year and his fifth victory in an undefeated campaign across all distances. Coleman, the 2019 world champion and one of the fastest men in history with a 9.76 PB, faces a formidable challenger in the shape of 2022 World Championships silver medalist Marvin Bracy-Williams. Bracy-Williams has run only twice in 2023 and was third at the Nairobi Continental Tour meet in his most recent outing, but with a PB of 9.85 and a history of rocket starts he will not let Coleman get a jump on him. Ronnie Baker is another man with sub-9.9 speed and was fifth at the Tokyo Olympics, setting his PB of 9.83. The runner-up at the Olympic Trials in 2021 has run 10.01 in 2023 after not running any 100s last year. Looking to add another major win to his resume, Cravont Charleston will try to capitalize on the windy 9.87 that carried him to victory at the Mt. SAC Relays last month, while Kendal Williams will be seeking his first wind-legal sub-10 clocking of the season. Jamaica's Ackeem Blake, who was third in Bermuda at 9.87w, will be in the mix with a legal best of 9.99 thus far. 200m: Last year's World Indoor champion at 400m, Jereem Richards of Trinidad, is a pretty fair hand at half that distance with a sixth-place finish at the World Championships and an eighth-place effort at the Tokyo Olympics, and he has a career best of 19.80 from last year. While he may enter as the paper favorite, many eyes will be on Terrance Laird, the 2021 NCAA 100m champion for LSU who has a pair of sub-19.9 clockings to his credit and is on the comeback trail after battling injuries. Laird was fourth in the 100m at Bermuda last week in 9.94w and is showing flashes of brilliance again. Nairobi Continental Tour winner Aaron Brown of Canada was sixth at the last Olympics and has a PB of 19.99, while his Canadian relay teammate, Jerome Blake, is knocking at the door of sub-20 territory. Fast-improving Elijah Morrow won at Bermuda in a very-windy 20.11 and has run a legal 20.15 already, in addition to a windy 9.97 in the 100m. Also a sub-10 100m man, Kyree King finished second at Nairobi behind Brown and was fourth at the Doha Diamond League meet. 400m: Grenada's Kirani James won Olympic gold in 2012 at London and 11 years later he hasn't lost too much of the speed that carried him to his 43.74 PB lo those many years ago. James took bronze at the Tokyo Games and won last year's Diamond League title after earning silver at the World Championships. Fastest among the American contenders is Trevor Stewart, who has twice broken 45 seconds in 2023 with a best of 44.92. Stewart, who has a 44.25 PB, picked up gold on the U.S. 4x400m relay at Tokyo and earned bronze in the mixed 4x400m. Better known as the 2019 NCAA 400m hurdles champion for South Carolina, Quincy Hall also has serious credibility without the barriers, winning the SEC flat 400m in 2019 and setting his PB of 44.53 that year. He has run three very respectable quarters this season, the fastest a 45.30 at the Jones Memorial meet in Florida. Wil London has a pair of World Championships relay golds for Team USATF and was the Diamond League second-place finisher last year. A 45.62 at the Seiko Golden GP in Japan last week indicated that Paul Dedewo is rounding back into the form that saw him to a superb 2018 season that included nine sub-45 outings, a 44.43 PB, a World Cup victory and a runner-up finish at the USATF Championships. 800m: Last year's USATF champion and the bronze medalist at the 2022 World Indoor Championships, Bryce Hoppel sits atop the U.S. list for 2023 at 1:45.59 and won the USATF Indoor title in February. Hoppel has four national titles to his credit, plus a pair of NCAA wins for Kansas, and has run 1:43.23. He will need to be in tip-top form against Kenyan youngster Noah Kibet, a 19-year-old who won the Millrose Games in a world indoor-leading 1:44.98 and was the World Indoor Championships silver medalist in 2022. Also lurking is 2016 Olympic bronze medalist Clayton Murphy, who was a Tokyo Olympics finalist and has a 1:42.93 PB. Murphy was fourth at the Doha Diamond League meet at the beginning of this month. A pair of Isaiahs, Jewett and Harris, will also be in the mix. Isaiah Jewett, owner of a 1:43.85 PB, was the NCAA champion for USC in 2021 and placed second at the Olympic Trials, while Isaiah Harris was seventh at the 2022 World Indoor Championships and won the 2018 NCAA title for Penn State. Harris was runner-up at this year's USATF Indoor Championships and has a lifetime best of 1:44.42 from 2018. 1,500m: A galaxy of stars converges for this metric mile, including Timothy Cheruiyot of Kenya, the seventh-fastest man in history and the 2019 world champion, 2016 Olympic champion Matthew Centrowitz, and 2023's fastest man, Reynold Kipkorir Cheruiyot of Kenya. Sprinkle in a handful of top Americans and this one promises to be compelling. Timothy Cheruiyot has run 3:28.28 in his career and was the silver medalist at Tokyo. He has only raced twice this year, at 800m and 3,000m, but can never be discounted. Centrowitz scored a historic win at Rio in 2016, the first American to win Olympic gold at 1,500m in more than a century, and his PB of 3:30.40 in 2015 ranks him among the fastest Americans ever. Reynold Cheruiyot won the Nairobi Continental Tour in 3:32.01 and is still eligible for U20 competition. Reigning USATF champion Cooper Teare has a PB of 3:34.81 and nearly beat that with his 3:34.96 to win the Bryan Clay Invitational in mid-April. The man who was third behind Teare at the USATF meet, Josh Thompson, ended up 12th in the World Championships final at Eugene, while Johnny Gregorek was a semifinalist at that meet and is a sub-3:50 miler. USATF indoor champion Sam Prakel set his PB of 3:34.92 last summer and captured the USATF Road Mile title last month. Hobbs Kessler is a precocious talent who just turned 20, and he holds the U.S. U20 record at 3:34.36 from 2021, and 2019 USATF indoor two mile winner Drew Hunter clocked 3:34.86 in 2022. One other youngster to keep an eye on is Kenya's Vincent Keter, the 2021 World U20 champion. 400m Hurdles: World Championships bronze medalist Trevor Bassitt had a breakout season in 2022, lowering his PB to 47.39 to move into the all-time world top 20. Kyron McMaster of the British Virgin Islands is the only faster man in the field, bringing a PB of 47.08 that he set to take fourth at the Tokyo Olympics. Fifth behind Bassitt at the World Championships last year, Khallifah Rosser has a best of 47.59 and was fourth at the Doha Diamond League meet three weeks ago. CJ Allen made a big breakthrough at that Doha meet, taking second in a PB 47.93, and gained notoriety for clocking 48.88 in the rarely run indoor version of this race in January. Tokyo Olympian David Kendziera won his first and only race of 2023 in 48.74 and has a best of 48.38 that earned him bronze at the 2021 Olympic Trials. Jamaica's Jaheel Hyde took sixth at Eugene last year in a PB 48.03 and was the Commonwealth Games silver medalist, and Gerald Drummond of Costa Rica slashed his PB to 48.11 earlier this month. Pole Vault: Every time he straps on his spikes and steps on a runway, Sweden's Mondo Duplantis is a threat to his own world record. Duplantis, the reigning Olympic, World and World Indoor champion, has cleared 6.00m/19-8.25 a mind-boggling 60 times in his career, and his PB of 6.22m/20-4.75 came indoors in February and raised his own WR once again. Should Duplantis falter, the top two Americans ever, Sam Kendricks and Chris Nilsen, will be happy to supplant him, as will KC Lightfoot and France's 2012 Olympic champion, Renaud Lavillenie. This year's USATF Indoors champion, Kendricks holds the American record at 6.06m/19-10.5 and won world titles in 2017 and 2019 as well as earning bronze at the 2016 Rio Games. Nilsen was the silver medalist at Eugene and Tokyo and is only a hair behind Kendricks with a 6.05m/19-10.25 indoor PB. Lightfoot joined the 6m club in 2021 and won the NCAA indoor title for Baylor before turning pro and placing fourth at the Olympics. In the twilight of a brilliant career, Lavillenie has won nine global medals and held the world indoor record with a 6.16m/20-2.5 clearance in 2014. Shot Put: Much as Duplantis has dominated the pole vault, Ryan Crouser has been The Man in shot put circles of late. With a staggering 203 career throws of 22m or better, Crouser is the two-time Olympic champion, reigning world champion, and world record holder. His PB of 23.37m/76-8.25 won the 2021 Olympic Trials and he has topped 23m in six meets in his career. New Zealand's Tom Walsh won the 2017 World Championships and has a pair of bronzes from the past two Olympics, and he threw his PB of 22.90m/75-1.75 at the Doha World Championships four years ago. Up-and-coming Josh Awotunde was a bit of a surprise last year when he took bronze at the World Championships with a big PB of 22.29m73-1.75, and this will be his 2023 debut. Last year's World Championships eighth-place finisher, Tripp Piperi, is a fiery competitor and has a best of 21.74m/71-4i, while Tokyo finalist Payton Otterdahl has introduced fashion options to the shot put ring and placed second at last week's USATF Throws Festival. He has a PB of 21.92m/71-11. Returning from injury, Darrell Hill was the 2018 USATF champion and has a PB of 22.44m/73-7.5 to rank in the all-time world top 20. Discus: 2019 World Championships silver medalist Fedrick Dacres of Jamaica and Alex Rose of Samoa have both surpassed 70m in their careers and will be looking for a friendly wind to near that distance again. Dacres is a two-time Olympian and four-time World Championships finalist who has a PB of 70.78m/232-3 from 2019. Rose won the USATF Throws Festival last week and has a best of 70.39m/230-11. Reigning USATF champion Andrew Evans threw his PB of 66.74m/218-11 last year, while Brian Williams made the U.S. squad for the past two World Championships. Josh Syrotchen upped his PB to 66.21m/217-2 in Oklahoma earlier this season. Hammer: Olympic champion Wojciech Nowicki of Poland and silver medalist Eivind Henriksen of Norway went 2-3 at last year's World Championships, and they will face American record holder Rudy Winkler, the winner at last week's USATF Throws Festival who has the best throw in the world in 2023 at 80.88m/265-4. Reigning USATF champion Daniel Haugh is one of only six Americans ever to top 80m, going 80.18m/263-1 to win the U.S. title, and he was eighth at the World Championships in Eugene. Canada's Ethan Katzberg has emerged as a world medal threat with a best of 78.41m/257-3 already at age 21. Other American contenders include 2022 USATF Championships bronze medalist Alex Young, a finalist at the World Championships who has a PB of 78.32m/256-11, and Sean Donnelly, the 2019 Pan American Games bronze medalist who has thrown 79.27m/260-1 in his career. Morgan Shigo is a steady hand who has a best of 76.10m/249-8. Javelin: Reigning world champion Anderson Peters of Grenada has a cannon arm and has surpassed 90m in four meets, topped by a 93.07m/305-4 at the 2022 Doha Diamond League meet that ranks him No. 5 on the all-time world performer list. Peters, who also won the 2019 world title, was the 2018 and 2019 NCAA champion for Mississippi State. Last year's USATF runner-up, Curtis Thompson, is the third-best American ever with a PB of 87.70m/287-9 and won the USATF Throws Festival last week. Capers Williamson was fourth at the USATF Championships last summer, and Michael Shuey was seventh. Shuey is fifth on the all-time U.S. list at 85.67m/281-1. Ethan Shalaway and Donavon Banks are also hovering around the 80m mark. Watch the competition live on NBC and Peacock on Saturday from 4:30 to 6 p.m. ET.
