Round 4 of the Zurich Classic suspended due to dangerous weather

The final round of the Zurich Classic has been suspended due to dangerous weather in the area.

Tournament officials moved up the Sunday tee times in hopes of avoiding the conditions, but were forced to blow the horn at 11:03 a.m. ET, and removed the players from the course.

Before play was called, Kevin Kisner and Scott Brown birdied their first six holes to sit at 21-under par, and take a one-shot lead over Jonas Blixt and Cameron Smith.
