Great Britain's Andrew Osagie secured his best finish at a Diamond League meeting with second place behind Kenyan David Rudisha over 800m in New York.
The 25-year-old clocked one minute 46.44 seconds but could make no impression on the Olympic champion (1:45.14) at the Icahn Stadium.
Christine Ohuruogu struggled to sixth in the women's 400m, as Botswana's Amantle Montsho eased to victory.
British former world champion Phillips Idowu missed the men's triple jump.
The 34-year-old had been
expected to make his first appearance since the London Olympics,
but will now compete in Rome on 6 June.
What is the Diamond League?
- A total of 14 meetings around the world, finishing in Brussels on 6 September
- Visits Birmingham on 30 June for the British Grand Prix and London on 26-27 July for the 2012 Anniversary Games
- Each one of the 32 disciplines (sixteen for men and sixteen for women) is staged a total of seven times during the season
- The top three athletes at each meeting are awarded points, and the points are doubled in the final meeting
- The athlete with the highest number of points in each discipline at the end of the season wins their Diamond League event
Wet and windy weather in New York created tough conditions for the athletes in the third of 14 Diamond League meetings over the summer.
Osagie finished eighth of nine at the last event
in Doha a fortnight ago,
but despite running more than a second slower in America, he was second home.
A strong closing 200m combined with a collision between chasing athletes ended any challenge for his place while Rudisha, 24, eased clear.
It was a different story for Ohuruogu, who failed to find any rhythm and clocked 52.08 seconds, almost two seconds slower than her time in Doha.
With Olympic champion Sanya Richards-Ross failing to make the start line, Ohuruogu was expected to figure prominently, but as she struggled her fellow 29-year-old Montsho dominated to win in 49.91 seconds.
European indoor champion Holly Bleasdale, 21, was sixth in the pole vault - her 4.23m effort well short of American winner Jennifer Suhr (4.63m) - while her fellow Briton Eilish McColgan, 22, finished eighth in the women's 3,000m steeplechase, which was won by Lidya Chepkurui of Kenya.
With August's World Championships in Moscow drawing ever closer, the Diamond League meetings in Birmingham on 30 June and London on 26-27 July are expected to draw a stellar cast of athletes.
