Krista Dotzenrod, 24, said she was surprised when the ball fell into her cup during Saturday's game against the San Diego Padres.
"I was told they were amazing seats because you can catch a lot of foul balls," Dotzenrod, who has lived in Chicago for seven years, told the Chicago Sun-Times. "I was sitting there, and all of a sudden there is a ball in my cup. It fell straight in there. I didn't know what to do."
"Everyone behind me told me to chug my beer," she said. "So I did. It was a Green Line beer from Goose Island."
"I chugged the beer and wished the Cubs a great year. The ball is now sitting in my apartment," she said.
Dotzenrod's wish for the Cubs was off to a good start Saturday -- they beat the Padres 7-6.
