When Davies, 54, opened the door to greet the men, one of them immediately punched her in the eye. That's when she remembered her son's bat.
"Next thing I knew, it was in my hand," she said. "I just swung as hard as I could."
She connected, hitting the closest thug in the shoulder. The duo fled immediately, and Davies ran upstairs, "into the arms of my daughter," she said.
"I was just in shock," she said. "I'm still trying to process what happened."
Davies said she walked away from the encounter with some bruising around her eye. A trip to Aria Health's Frankford hospital revealed she sustained a concussion during the attack.
Cheryl Davies, who comforted her mother after the attack, was furious that the thugs would be so bold.
"My mother has Crohn's disease; she's clearly a sickly woman," Davies said. "Never in a million years would I expect someone to punch someone so frail in the face."
Police yesterday said they were looking for the two suspects. Cheryl Davies said footage from her neighbor's private surveillance cameras was turned over to police.
But until these men are caught, Diane Davies has one piece of advice for city residents:
"Unless you specifically call for utility workers, don't open your door for them," she said.
"Otherwise, they shouldn't be showing up at your house."
