Gun Runner arrives on a three-race winning streak, all Grade 1 stakes, for trainer Steve Asmussen. The 4-year-old posted dominant victories in the Stephen Foster at Churchill Downs and the Whitney and Woodward Stakes at Saratoga. His last defeat was to Arrogate in Dubai.

WNBA: Seattle Storm star Breanna Stewart says she was sexually abused as a child.

Stewart describes the abuse in an essay posted Monday on the Players’ Tribune website.

Stewart says she was first molested at a relative’s house in upstate New York when she was 9 by a man who continued the abuse for two years.

Stewart says she eventually told her parents, who called police. She says the man was arrested and confessed but doesn’t indicate what happened to him.

Her essay is titled “Me Too,” a nod to the social media movement started following abuse allegations against Hollywood mogul Harvey Weinstein.
