Shaun White finishes 4th in halfpipe at his final Olympics

In Shaun White's farewell performance on Friday, Ayumu Hirano of Japan won an elusive Olympic gold in the halfpipe with a boundary-pushing final run.

There was no doubt about the winner after Hirano's electric performance as the last rider to go. His run included an intricate and unprecedented series of flips and spins that pushed a sport obsessed with progression to new heights. His score of 96 reflected that and the two-time Olympic silver medalist moved past Scotty James of Australia, who scored 92.50. Jan Scherrer of Switzerland took bronze.

White finished in fourth place as he fell on the final run of a career that's seen the American star win three Olympic titles. He lifted up his goggles and waved to the crowd on his way down the halfpipe. He teared up as the sparse crowd bid adieu to the 35-year-old and fellow riders lined up to hug him.
