Share Updated: 8:51 PM CDT Aug 3, 2021 By JENNA FRYER, AP Sports Writer The main action for Day 12 of the Tokyo Games is at Olympic Stadium with live track & field events. A world record could be set in primetime when defending Olympic champion Ryan Crouser tries to break the shot put mark. Nevin Harrison is the only athlete representing the United States in canoe sprint and the gold medal favorite in the women’s canoe 200, and April Ross and Alix Klineman will play for a spot in the women's beach volleyball gold medal match.Here are some things to watch (all times Eastern):Track & FieldIt will be a world record watch at Olympic Stadium in Wednesday's track and field competition.Ryan Crouser will attempt to break his own world record and win a second consecutive gold medal in the shot put.To comprehend Crouser’s record, try throwing a 16-pound bowling ball from one free throw line all the way to the opposite end of a basketball court. That’s essentially what he did at the U.S. Olympic trials in June, when he broke a 31-year-old record with a throw of 23.37 meters (76 feet, 8¼ inches).U.S. teammate Joe Kovacs won silver at the Rio Games, but at the 2019 world championship in Doha the duo flipped the finishing order with Kovacs beating Crouser, who wound up second.In the 110-meter hurdles, world champion Grant Holloway will be the one to catch. He turned in the second-fastest time in the history of the event in the Olympic trials, running 12.81 seconds — just 0.01 seconds behind the time Aries Merritt set in 2012.And in the 200-meter final, Erriyon Knighton could be in the mix for a medal. The 17-year-old from Florida is the youngest male track Olympian to represent the U.S. since Jim Ryun in 1964, and at trials Knighton broke the under-20 world record held by none other than Usain Bolt.During his first-round run in Tokyo, Knighton was caught mid-yawn before his heat in the first round. His biggest rival will be teammate Noah Lyles, who is the reigning world champion. Canoe SprintNevin Harrison is the only athlete representing the United States in canoe sprint and the gold medal favorite in the women's canoe 200.Harrison won the 2019 world championship at just 17 years old, and she won a world cup series title in May. She took up the sport at the urging of a summer camp counselor when she was 12 years old.She also has a chance to be the first female Olympic champion in the event. The canoe 200 was added this year as part of the Olympics’ efforts at gender equity. It has been part of the canoe world championships for several years. Beach VolleyballApril Ross and Alix Klineman will play for a spot in the women's beach volleyball gold medal match against Switzerland.The Americans knocked out Germany and defending Olympic champion Laura Ludwig in the quarterfinals, leaving Ross as the only woman remaining in the beach volleyball tournament with an Olympic medal on her resume.Ross won silver in London in 2012 and bronze in Rio de Janeiro in 2016. Women's Golf The second round of women's golf features the top 14 players in the world, led by top-ranked Nelly Korda. The 23-year-old Floridian is the daughter of tennis player Petr Korda, who won the 1998 Australian Open.Of the 60 players, 29 have returned from the Rio Games, the first time golf was played in the Olympics in more than a century. All three medalists from Rio are back, including winner Inbee Park of South Korea.The Americans and South Koreans are the only countries that have the maximum four players. It has been a strong year for the American golfers with six LPGA wins — the most of any country on a tour that has been dominated by the South Koreans for the past decade.The rough has been trimmed significantly since American golfer Xander Schauffele won the men's tournament at 18-under par. The men required a seven-way playoff to determine the bronze medalist and a playoff of some variety for the women would not be a surprise. Women's BasketballThe U.S. women's basketball team will face Australia in the next step toward a seventh consecutive Olympic gold medal.Australia beat the U.S. in an exhibition last month in Las Vegas and will challenge a U.S. team that hasn't been quite as strong in the Tokyo Games as past years. The U.S. and Australia are ranked No. 1 and 2 in the world, but Australia has never beaten the U.S. in the Olympics.The Opals lost to the Americans in the gold medal game in 2000, ‘04 and ’08. The Australians also lost in the semifinals of the 1996 and 2012 Olympics to the U.S. as well.The Americans have won 52 consecutive Olympic contests going back to the bronze medal game of the 1992 Olympics. Sport Climbing The Olympic debut of sport climbing continues with women's qualifying, which includes an element of surprise in that the climbers won’t get a chance to see the wall in two of the three disciplines until right before their first attempt.Climbing at the Olympics will have three disciplines: lead, boulder and speed.Lead is pretty much what recreational climbers face at climbing gyms, only on a much higher wall (15 meters) and far more difficult. There’s a six-minute limit, whoever climbs highest wins.Bouldering is a set of four "problems" on 4.5-meter walls where turning upside down is sometimes the solution to reaching the top. Climbers have five minutes — four in the final — to solve each boulder in as many attempts as they want.Speed is a race to the top of a 15-meter wall on a standardized route.
