Woodward, Okla. — LONDON (AP) — Michael Phelps has always said he wanted to do something that no one has ever done before.
He's all by himself now, and ready to go for more.
The world's greatest swimmer cruised through the anchor leg of the 4x200-meter freestyle relay to earn his record 19th career Olympic medal and 15th gold on Tuesday night, etching a place in history as the most decorated Olympian of all time.
"It has been a pretty amazing career but we still have a couple races to go," he said.
Now his remaining four days in the pool at the London Games are all about putting that mark even further out of reach. Phelps has three events to go — the 200 individual medley, the 100 butterfly and the 4x100 medley relay.
He won't be racing for a medal on Wednesday, when he competes in the preliminaries and semifinals of the 200 IM.
The big race on Day 5 of the swimming competition will be the men's 100 freestyle. James "The Missile" Magnussen of Australia owns the leading time going into the final. Nathan Adrian of the U.S. is next on the list, followed by Cuba's Hanser Garcia.
Other top contenders are world record-holder Cesar Cielo of Brazil and Yannick Agnel of France.
Kosuke Kitajima will try to make some history of his own in the 200 breaststroke. The Japanese star could become the first male swimmer to win the same event at three consecutive Olympics, although he's a long shot after qualifying fifth-fastest for the final. Kitajima's earlier attempt at a threepeat in the 100 breast fell short.
Leading qualifier Kathleen Hersey goes for the first U.S. gold medal in the women's 200 butterfly since 2000, when Misty Hyman stunned Susie O'Neill in Sydney.
