Add another gold medal to Katie Ledecky’s burgeoning collection.
The 18-year-old American won the 200 metre freestyle at the world swimming championships on Wednesday night against a stellar field that included defending champion Missy Franklin of the United States and two-time winner Federica Pellegrini.
Ledecky rallied from fourth after the first two laps to touch first in 1 minute, 55.16 seconds for her second gold medal of the championships. She already won the 1,500 free, lowering her own world record in the preliminaries and final.

Pellegrini of Italy finished second in 1:55.32, and Franklin was third in 1:55.49.
Femke Heemskerk of the Netherlands took it out strongly, dipping under world-record pace on the opening lap. She was still in front through the third lap before fading to eighth.
