A Major League Baseball player is being investigated in an alleged sex assault.

FOX's Chris Hoenig reports:

Pittsburgh Pirates infielder Jung Ho Kang is a person of interest after a Chicago woman told police she was raped in a city hotel room. The incident happened June 17, hours after the Pirates lost to the Cubs.

According to the allegation, Kang met the victim through an online dating app and invited her to his hotel room where he served her a drink, 15 to 20 minutes later, she blacked out, drifting in and out of consciousness as she was assaulted.

The 23-year-old victim said she only became aware of her surroundings in a cab on her way home, and went to a hospital, where a rape kit was done.

Kang is a 29-year-old South Korean in the second year of a four-year, $11 million contract. He finished third in National League Rookie of the Year voting last year.
