A minor league shortstop in the Pittsburgh Pirates organization has returned home to South Korea because of a police investigation into allegations he physically assaulted his ex-girlfriend.

Ji-hwan Bae, 18, left the team's training complex in Bradenton, Florida, where he was awaiting the start of the rookie-level Gulf Coast League season.

The woman filed a police report this week alleging that Bae slapped, choked and kicked her on New Year's Eve in 2017, according to Chinese reports.
