Detroit police revealed in April that they were investigating a sexual assault claim against Reed.
According to Wayne County Prosecutor Kym Worthy, Reed met a 45-year-old woman at a bar outside Detroit around midnight on March 30.
"At some point, the (woman) finished an alcoholic drink and began to feel odd," a news release from Worthy's office said (via the Detroit Free Press).
Reed left the bar with the woman and took a cab to a downtown Detroit hotel, where the woman alleges Reed sexually assaulted her at 7:30 that morning.
Reed faces a maximum of 15 years in prison.
Reed pitched the seventh inning of Detroit's season opener on March 31. He appeared in 27 games before he was designated for assignment on June 18. Reed was then sent to Triple A Toledo, where he has appeared in eight games.
