Last week, the first salvo in the expected legal battle between the PGA Tour and LIV Golf Invitational Series was fired when Phil Mickelson and 10 other LIV players sued the PGA for antitrust claims.

The lawsuit, filed Aug. 3 in the U.S. District Court for the Northern District of California in San Francisco, was brought by 10 of the 24 players who have been suspended from the Ponte Vedra Beach, Florida-based PGA for defecting to the LIV tour and one (Jason Kokrak) who is expected to be suspended soon. The players had requested releases from the PGA so they could play in LIV tournaments on the same weekends as scheduled PGA events, and were denied.
