‘‘It wasn’t a perfect race, but the good thing was that I won and I came out injury free,’’ said Bolt, who got away slowly but powered home, catching the field at about 50 meters and celebrating as he got to the line first to the delight of a big crowd at the national stadium in Kingston.
The sprint superstar led three compatriots under 10 seconds in a race run in a wind of one meter per second.
Nickel Ashmeade and Yohan Blake were both timed in 9.94sec, with Asafa Powell finishing in 9.98.
The race was only the fourth time that Bolt, former world record holder Powell and 2011 world champion Yohan Blake have clashed in Kingston and more than 30,000 fans turned out for the warm up for Jamaica’s Olympic trials later this month.
Powell had hoped for better, running fourth despite what he described as a calf cramp.
Running before his home crowd for the first time in about two years, Bolt said: ‘‘It’s good to be back, it has been a while since I ran here.’’
While Bolt said execution was key in the 100m, he was pleased to overcome his technical flaws on the night.
‘‘Even when you don’t get it right you have to stay strong, composed and run through,’’ he said.
‘‘I was not completely happy with execution as the start was horrible and did not set up the race, but I won and that is good.’’
Bolt improved on the 9.98sec he posted in Ostrava on May 20.
With the August 5-21 Rio Games less than two months away, Bolt moved ahead of US rival Justin Gatlin on the 2016 world list, the American owning a time of 9.93 that puts him fourth-fastest in the world this year.
France’s Jimmy Vicaut owns the fastest time in the world in 2016, 9.86sec at a meeting in Montreuil on June 7.
World and Olympic champion Shelly Ann Fraser-Pryce won the women’s 100m in a subdued 11.09sec, coming back from a toe injury that has hampered her training.
