Olympic silver medallist Thompson clocked 9.85sec to win the men's 100m, confidently following up on his blistering 9.75sec at the Jamaican national trials that made him the sixth-fastest man all-time at the distance.
Thompson easily out-paced Britain's Zharnel Hughes (9.91) and American Trayvon Bromell (9.94) and said the race was another learning experience as he gears up for an expected world title tilt against American Noah Lyles -- who bested him by just .005sec for Olympic gold in Paris.
"I'm the only one that can stop me," Thompson said. "I don't say that to brag but to be honest. Once I better my execution, amazing things are going to happen."
Jefferson-Wooden outdueled Olympic champion Julien Alfred in the women's 100m, holding off the Saint Lucia star to win in 10.75sec.
That was just outside her season-leading 10.73 set at the Philadelphia Grand Slam Track event, but impressive in a headwind of -1.5 meters per second.
Alfred was second in 10.77 and Ivorian Marie-Josee Ta Lou-Smith came third in 10.90.
American Sha'Carri Richardson, who revealed this week that an injury in February had slowed her season start, finished ninth in 11.19sec.
Sweden's two-time Olympic champion Armand "Mondo" Duplantis won the pole vault with a leap of 6.00m.
Duplantis finished comfortably ahead of Americans Sam Kendricks and Austin Miller, who took second and third with clearances of 5.80m, but he came up empty on three attempts to better the world record of 6.28m that he set in Stockholm three weeks ago.
In addition to records, there were multiple world-leading performances.
Rising Ethiopian talent Biniam Mehary, 18, won the 10,000m in 26:43.82. Botswana's Olympic champion Letsile Tebogo won the 200m in 19.76sec and Bahrain's Olympic champion Winfred Yavi threatened a world record on the way to a world-leading 8:45.25 in the 3,000m steeplechase.
Rudy Winkler set an American record in winning the hammer with a throw of 83.16m, American Joe Kovacs won the shot put at 22.48m and Olympic long jump gold medallist Tara Davis-Woodhall equalled the season's best with a 7.07m leap.
