Some of the sports stories The Associated Press is covering Wednesday. A full Sports Digest will be sent about 3 p.m. All times EDT:

- KAZAN, Russia - Katie Ledecky wins the 200-meter freestyle at the world swimming championships against a stellar field that includes defending champion Missy Franklin and two-time winner Federica Pellegrini. The 18-year-old American rallies from fourth after the first two laps for her second gold medal of the championships, with Pellegrini second and Franklin third.

- OXNARD, Calif. - Charles Haley still moves along the sideline with a gruff look on his face, chiding reporters and team personnel. There's always a hint of a smile now, though. It wasn't an act 25 years ago, before the pass-rushing standout was traded from San Francisco to Dallas in the middle of what turned into a Hall of Fame career for the only player with five Super Bowl rings.

- NEW YORK - Prized pitching prospect Luis Severino makes his much-anticipated major league debut for a first-place New York Yankees team that could use help in the rotation. On the mound for the rival Boston Red Sox is knuckleballer Steven Wright. Game starts 7:05 p.m.

- NEW YORK - With next year's Olympics in Brazil, NBC will be able to show many major events live in prime time in the U.S. It's an appealing proposition but also offers challenges for a network that has continued to find success airing tape-delayed competition at night.

- Michael Phelps is still focused on going fast in the pool. Outside the water, he's made some big changes.

- PITTSBURGH - The Chicago Cubs look to extend their winning streak to seven games against the Pittsburgh Pirates. Dan Haren will make his first start for Chicago against Pittsburgh's Jeff Locke. Game starts 7:05 p.m.

- NASHVILLE, Tenn. - Dick LeBeau's love of guitars makes him a perfect fit in Music City, and the history buff is a short drive from a handful of Civil War battlefields. But the Hall of Fame player and defensive coaching whiz hasn't had much time for either with Tennessee putting him to work for his 57th season in the NFL overseeing the Titans' defense.

- ST. JOSEPH, Mo. - On the first day of training camp, Jeremy Maclin hauled in a long touchdown pass from Alex Smith. Just like that, the Chiefs' new No. 1 wide receiver had more TD catches than their entire wide receiver corps last year.

- BOURBONNAIS, Ill. - Adam Gase is quarterback Jay Cutler's fifth coordinator with the Chicago Bears, and so far the pairing seems to be off on the right foot, even with injury concerns at the wide receiver position limiting the offense at times.
