The scary moment happened at San Diego's Petco Park on Saturday.
Stay safe, Taylor Swift!
The singer's security got a major workout in on Saturday when they were forced to intercept a man attempting to charge the stage at Swift's 1989 Tour stop in San Diego. The scary moment was caught on camera by fans in the audience.

ET has confirmed that the stage crasher is 26-year-old Christian Ewing (who, like Swift, was also born in 1989). He was arrested in the early hours of Sunday and charged with entering a venue without a ticket, along with felony and misdemeanor battery, and obstruction.
