Berlin (AFP) - Olympic 100m champion Lamont Marcell Jacobs marked his long-awaited return to the track with victory in the 60 metres at the Berlin indoor meet on Friday, while pole vault star Armand Duplantis agonisingly missed out on breaking his own world record.
Italian sprinter Jacobs won in a time of 6.51sec in his first appearance since stunning the sport at the Tokyo Games in August.
Jacobs, the European champion over 60m, had said on the eve of the event that he had come to Berlin "just to win".
He was as good as his word, seeing off Ivory Coast's Arthur Cisse (6.60sec) and Jimmy Vicaut of France (6.61sec) at the finish.
"I'm very happy with my feelings in this first race," Jacobs, who spent the last month in a warm-weather training camp in the Canary Islands, told AFP.
"I hope to run a little faster but after such a long period without competition it's normal to take time to rediscover the rhythm."
The 27-year-old Jacobs had not competed since he won double gold in the 100m and 4x100m relay in Japan and prepared for his return in Germany by addressing head-on the suspicions which lingered over his surprise Olympic triumphs.
"I would never do anything as an athlete competing for my country that would bring disrepute on me as a man or on my nation," Jacobs told the Daily Telegraph in an interview last week, when asked directly if he had ever taken banned performance-enhancing substances.
His stated goal for the indoor season is to break the European 60m record of 6.42sec, held since 2009 by Britain's Dwain Chambers.
"In Tokyo, in the semi-finals and final of the 100 metres, I had passed the 60 metre mark by breaking this record, so my goal is to find that form again," he added.
Meanwhile, Olympic champion and pole vault world record holder Duplantis improved on his best performance of the season.
The Swede cleared 6.03m, a centimetre more than he achieved at Karlsruhe last week in his first appearance of the year.
He then tried to set a new world record of 6.19m, hoping to beat his own mark of 6.18m.
He came agonisingly close on his third attempt with the bar wobbling before falling to the ground.
"I really liked my second attempt because I felt like I had the height to pass," said the 22-year-old Swede who rattled the bar.
He added: "I'm at a point in my career where I'm progressing in small steps.I know what I have to do, I have all the pieces of the puzzle to beat my personal record."
