The season was severely impacted by the COVID-19 pandemic, with half the scheduled tournaments being cancelled, including four of the five senior majors.

As a result the only major played in 2020 was the Senior Players Championship, which was won by Jerry Kelly, who finished two strokes ahead Scott Parel to claim his first senior major title.

The season was expanded to include all 2021 tournaments with the Charles Schwab Cup Playoffs events in 2020 returning to regular event status.
