Powell celebrates his 100m win

Powell, the world record holder from Jamaica, won the 100m in 9.86 seconds from American Tyson Gay.

American Wariner, the 400m World and Olympic champion, held off Congo's Gary Kikaya to win in 44.26secs.

Richards, another American, won the women's 400m in 49.81secs in front of a 48,000 crowd at the Olympiastadion.

Richards finished just over a second in front of compatriot Dee Dee Trotter.

The trio shares a $500,000 purse, working out at $166,666 apiece, for winning all six of their races in the Golden League meetings provided they appear at the World Athletics Final in Stuttgart next weekend.

They will add that to one-sixth shares in a separate $500,000 jackpot ($83,333 each) for athletes winning their events in at least five of the six meetings.

Tirunesh Dibaba, who was also in line for the double jackpot going into the Berlin meet, was edged out by world record holder Meseret Defar in a thrilling finish to the women's 5,000m.

Dibaba held a slight lead going down the final straight, but a devastating late kick form her Ethiopian compatriot Defar saw her take the lead inside the final 10 metres.

Dibaba had to settle for the $83,333 on offer for five wins.

Two other athletes clinched shares of that part of the pot when they recorded their fifth victories on Sunday.
