BEIJING - (AP) - Michael Phelps has won a record 10th career Olympic gold medal, earning his fourth gold at the Beijing Games with a world record in the 200-meter butterfly.
The American touched in 1 minute, 52.03 seconds, lowering his old mark of 1:52.09 set at last year's world championships in Australia.
Phelps' win has broken a tie with Mark Spitz, Carl Lewis and two others for most Olympic golds in a career. He is 4-for-4 so far, setting world records in each of his events.
Laszlo Cseh of Hungary took the silver in 1:52.70. Takeshi Matsuda of Japan got the bronze in 1:52.97.
Phelps will compete as a member of the 800-meter freestyle relay team later in the day.
If the team wins, Phelps will still have a chance to win a record eight gold medals in Beijing.
