As of my last update in September 2021, Phil Mickelson joining LIV Golf, a proposed Saudi-backed golf league, was a significant development in the golfing world. However, the specific reasons behind his decision were not extensively covered in the public domain up to that point.
If there have been new developments or information regarding Phil Mickelson’s decision to join LIV Golf after September 2021, such as specific motivations or factors influencing his choice, I would not have access to that information.
To understand the real reason behind Phil Mickelson’s decision to join LIV Golf, it would be advisable to consult recent and reliable sources for up-to-date information on the subject. Golf news outlets, interviews with Mickelson, or official statements from involved parties may provide insights into his rationale for becoming a part of the LIV Golf venture.
