MESA, Ariz. (AP) — Olympic gold medalist Katie Ledecky won the women's 1500-meter freestyle Wednesday night in the Arena Pro Swim Series event at the Skyline Aquatic Center.

Ledecky, the world record-holder in the event, finished in 15 minutes, 42.23 seconds, touching nearly a full 50 meters in front of second-place Kristel Kobrich of Chile.

"I think it was really good for me to swim it just because I haven't raced in two months," Ledecky said. "I sort of shook the cobwebs off and got a jump on the meet tonight."

Marcelo Acosta of El Salvador won the men's 800 free in 8:10.85.
