Katie Ledecky reached for the wall.
Someone else was already there.
For the first time ever at the world championships, Ledecky knows what it's like to lose.
Bidding to become only the second female swimmer to win six golds at a single worlds, Ledecky settled for silver in the 200-meter freestyle Wednesday evening when Italy's Federica Pellegrini surged to a stunning victory on the final lap.
Pellegrini, the world-record holder, avenged a close defeat at the hands of Ledecky two years ago in Kazan, Russia. This time, it was the Italian touching first in 1 minute, 54.73 seconds.
Ledecky and Australia's Emma McKeon tied for the silver at 1:55.18.
