Michael Phelps got up to leave his last news conference at the Olympic pool when his relay mates were asked if they thought he would really stay retired. Before they could answer, Phelps smiled and said emphatically: "Yes, yes." The most decorated Olympian called it a career last night with a fitting ending: a gold medal in the 4x100-meter medley relay. Phelps' totals in four Olympics: 22 medals, 18 golds, 51 races, and 9,900 meters of swimming. "I've been able to do everything that I wanted," he said. "If you can say that about your career, there's no need to move forward. Time for other things."
The 27-year-old has some ideas on what to do with his new-found free time: going cage diving among great white sharks in South Africa with Chad le Clos, the last man to beat him in the Olympics; playing golf and poker; and cheering on his hometown Baltimore Ravens. As for how that final race went, Phelps regained the lead in the medley relay with his trademark butterfly stroke, then handed it over to freestyle anchor Nathan Adrian, who brought it home in 3 minutes, 29.35 seconds. Japan took the silver in 3:31.26, and Australia got the bronze in 3:31.68. The team of Matt Grevers, Brendan Hansen, Phelps, and Adrian hugged it out before Phelps waved and smiled to the crowd. The Americans dominated the medal count at the pool, finishing with 16 golds and 30 overall. (Read more 2012 London Olympics stories.)
