Dallas Latos, who is married to Reds starting pitcher Mat Latos, tweeted out that she was punched three times and grabbed by the hair by an angry female fan at a sports bar outside Pittsburgh's PNC Park.
The Reds-Pirates game was Pittsburgh's first appearance in the playoffs since 1992 — and the end of 20 straight losing seasons.
Mrs Latos tweeted: "Look. Check the police report. I was ambushed in the Budweiser bar, grabbed by the hair, drug down & punched in the head multiple times."
A Pittsburgh police desk officer could not confirm whether Mrs Latos had filed a report of an assault on Tuesday night.
"Got punched in the head at least 3 times by a pirates fan so this has been cool," Latos tweeted.
She claims she was threatened by the boyfriend of the woman who attacked her. Latos, who married her husband in 2010, says she was appalled by how poorly the security at PNC Park and Pittsburgh police handled the alleged attack.

"Every opportunity was given to pirates security to deal with this before it happened. Unbelievable," she said.
"Only said something bc I’m shocked by how s****y that was handled by PNC security. Beyond," she added.
Mat Latos did not play in Tuesday night's Wildcard playoff game. The Reds lost 6-2, moving Pittsburgh into the NL Divisional Series against St. Louis — while Cincinnati's season is over.
