With the Sox pounding the Cubs again on Sunday, tensions were high among fans.
Such a heated intra-city rivalry has led to fan violence during past Crosstown Classic matchups both on the North and South Sides.
On Sunday, tempers boiled over again in the left-field bleachers at Guaranteed Rate Park and multiple cellphone cameras caught the incident.
It’s difficult to determine what caused fight. In the minute-long video, we see finger pointing by a Cubs fan and another fan climbing up three rows to confront someone before getting pushed to the ground by a third fan, which became the spark to spur the fighting.
