From AP's Paul Newberry at the swimming:

"Seventh at the turn, an Olympic champion at the end. Make it 17 gold medals for Michael Phelps.

What a way to go out in the final individual race of his career.

With those long arms whipping through the water, Phelps was next-to-last when he touched the wall at the far end of the pool in the 100-meter butterfly but in a familiar position when he made the touch that counted Friday — his name atop the leaderboard, a smile on his face, another gold medal around his neck."

And from Phelps: "I'm just happy that the last one was a win. That's all I really wanted coming into the night."
