Ledecky wins again

Katie Ledecky led wire-to-wire in the 400-meter freestyle Friday night for her third title of the week in the U.S. National Championships at Indianapolis. Ledecky broke her own U.S. Open record with a time of 3 minutes, 58.44 seconds. Leah Smith was second in 4:03.77 — the third time this week the duo went one-two. Ledecky has qualified in four individual events for the world championships next month. Lilly King raced to her third victory in three nights, setting a championship record with a time of 1:04.95 in the 100 breaststroke. She swept the three breaststroke titles. The other winners were Kevin Cordes, who retook the American record in the men’s 100 breast at 58.74, 32-yearold Matt Grevers in the men’s 100 backstroke, and Kathleen Baker in the women’s 100 back.
