A woman has been accused of running down and killing a man in her car following a Yankees-Red Sox argument outside a bar in Boston.

“She never braked, and she accelerated at a high speed for about 200 feet. She went directly at this group of people,” prosecutor Susan Morrell said of Ivonne Hernandez, who is charged with reckless second-degree murder in the death early Friday of Matthew Beaudoin, 29.

Authorities won’t describe the argument beforehand in Slade’s Food & Spirits, but witnesses said it heated up when Hernandez identified herself as a New York Yankees fan. Like the rest of New Hampshire, Nashua, 45 miles northwest of Boston, is Red Sox country.

Bartender Tanya Moran said the argument spilled outside, and at least one person in a group that included Beaudoin began chanting “Yankees suck!” when they saw a Yankees sticker on Hernandez’s car.
