Day 4 of track and field at the Tokyo Olympics was Monday in Japan, or Sunday night into Monday morning stateside.
There were finals in the women's 100m hurdles, women's discus, women's 5000m, men's long jump and men's steeplechase.
Other notable events included: semifinals in the women's 400m hurdles, men's 400m and women's 200m; first rounds in the women's 1500m and women's 200m; and qualifying in men's hammer and women's pole vault.
Four-time reigning world champion Pawel Fajdek of Poland, who's yet to earn an Olympic medal, advanced to his very first Games final with a 76.46m toss on his third attempt.
Fajdek threw 74.28m on his opener, short of the 77.50m auto-qualifying mark, then fouled on his next attempt. His third was still shy but ultimately sent him through as the ninth best.
His compatriot Wojciech Nowicki had the top overall throw in 79.78m. In Rio he took bronze, a medal he also won at the last three world championships behind Fajdek from 2015-2019.
Behind him in the second-best qualifying spot was U.S. champion Rudy Winkler with 78.81m. He who broke the American record at U.S. Olympic Trials in June, heaving 82.71m.

1st Round (8:35pET)
Reigning world champion Sifan Hassan of the Netherlands continued her historic quest to triple with her second event's prelim following the 5K, winning her heat in a uniquely extreme way.
Headed into the first turn of the bell lap the mile world record-holder met the end of a chain-reaction jostle, tripping over another runner and falling to the track. About 35 meters back, she got up and dropped the hammer, striding to reel the field back in by the homestretch and claim the lead right before finishing 4:05.17. She split 43.7 on the final 300m.
There's no rest for Hassan who's competing in her first of three finals around 12 hours later in the 5000m, an event in which she took bronze at the 2017 World Championships.
Defending Olympic champion Faith Kipyegon of Kenya, runner-up to Hassan at the most recent world championships, won her heat in 4:01.40, the fastest of the prelims round.
All three Americans — Heather MacLean (4:02.40, fifth overall), Cory McGee (4:05.15, 16th) and Elle Purrier St. Pierre (4:05.34, 19th) — made it through to the semifinals.

Men's Long Jump
RECAP | START LISTS | STREAM
World leader Miltiadis Tentoglou won gold on his final attempt, leaping 8.41m (24 ft, 3.75 in) to match 2019 world bronze medalist Juan Miguel Echevarria of Cuba, then assumed the lead on a countback tiebreaker based on his second-best jump of 8.15m.
Echevarria, who had a season-best 8.50m (27 ft, 10.75 in) to top the qualifying round, still had another attempt remaining but was clearly battling an injury. He struggled to the board and dropped to his knees before takeoff, visibly in pain and frustration.
Tentoglou won gold in his best global event finish, previously 10th place at the 2019 World Championships. Echevarria earned silver, and his teammate Maykel Masso, who entered as the lowest ranked athlete in the field, took home bronze with 8.21m.
American JuVaughn Harrison finished in fifth place. He took seventh in the high jump on Sunday night. It's only the fourth time in Olympic history the U.S. hasn't produced a medalist.
1st Round (9:30pET)
Tokyo Olympic 100m bronze medalist Shericka Jackson of Jamaica didn't advance out of her first-round heat after appearing to take it too easy while crossing the finish. She and Italy's Dalia Kaddari both clocked 23.26 in a photo-finish for the third and last auto-qualifying, and Kaddari ultimately got to the line first by four milliseconds.
Namibian Christine Mboma won heat four, the fastest of the prelims, to equal Allyson Felix's world under-20 record from 2003 in 22.11. American Gabby Thomas was second in 22.20.
Shelly-Ann Fraser-Pryce, who took silver in the Tokyo Olympic 100m, won heat three in 22.22. Switzerland's Mujinga Kambundji, Ivorian Marie-Josee Ta Lou, Jenna Prandini of the U.S., Canada's Crystal Emmanuel and Bahamian Anthonique Strachan were the other prelim winners.
Strachan's compatriot Shaunae Miller-Uibo, the defending Olympic 400m gold medalist, and Tokyo Olympic 100m champion Elaine Thompson-Herah also made it through safely.

Jamaican Elaine Thompson-Herah, who already successfully defended her 100m title, appeared well on her way to repeating her sprint double from Rio after winning the second semifinal in a blistering 21.66, equaling her personal best from the 2015 World Championships.
Namibia's Christine Mboma was second in 21.97, breaking Allyson Felix's 22.11 world under-20 record from 2003 after matching it in the first-round prelims. Her compatriot Beatrice Masilingi was also second, in heat one, clocking a personal-best 22.40.
Gabby Thomas of the U.S. was third in the section running 22.01, but easily made it to the final on time as semifinal two was the fastest.
Thompson-Herah's fellow countrywoman Shelly-Ann Fraser-Pryce, the 100m silver medalist and third-fastest of the prelims, comfortably won the first semifinal in 22.13. Thomas' teammate Jenna Prandini took fifth and did not advance.
And after edging her in the first-round prelims, Ivorian Marie-Josee Ta Lou again defeated Shaunae Miller-Uibo of the Bahamas in the third semifinal, running a season-best 22.11.

Women's 100m Hurdles
Puerto Rico's Jasmine Camacho-Quinn redeemed an early exit in Rio, defeating world record-holder Keni Harrison of the U.S. to win her nation's first women's track and field gold medal.
The winning time of 12.37, while still incredibly respectable, wasn't as fast as her semifinal in which she broke the Olympic record in 12.26.
Harrison's silver capped a five-year quest since missing the U.S. Olympic team in 2016, after which she took down the all-time record weeks later and watched as the U.S. swept the podium.
Women's Pole Vault
Heavy rain complicated the competition, which was briefly suspended.
Among those who qualified, all clearing 4.55m: defending Olympic champion Katerina Stefanidi of Greece, reigning world champion Anzhelika Sidorova of the ROC, 2015 world champion Yarisley Silva of Cuba and U.S. champion Katie Nageotte.
Nageotte's teammate Sandi Morris, silver medalist at the last three global championships, struggled in the rain and even snapped her pole, clearing just one height 4.40m to miss the final. Australian Nina Kennedy and Canadian Alysha Newman also did not advance.
Kirani James of Grenada, the 2012 Olympic champion and 2016 runner-up in Rio, blasted through his semifinal section in 43.88 – the second-fastest time this year at the distance – to make his third straight Olympic final.
Reigning world champion Steven Gardiner of the Bahamas won a loaded section in a season-best 44.14, beating American Michael Norman and defending Olympic champion and world record-holder Wayde van Niekerk of South Africa, who missed the final in fifth.
American Michael Cherry won the second semifinal in 44.44.

Women's 400m Hurdles
In a torrential downpour, world record-holder Sydney McLaughlin (53.03), defending Olympic and reigning world champion Dalilah Muhammad (53.30) and No. 4 all-time 400m hurdler Femke Bol (53.91) of the Netherlands all won their respective semifinals to make the final.
It marks the first Olympic final for Sydney McLaughlin, who didn't make it out of the semifinal round at the 2016 Rio Games.
American Anna Cockrell also made it through to the final.
