Is the PGA Senior tour the same as the Masters?

Answer 1

A "PGA tournament" is any tournament on the PGA Tour while the Masters is a specific single tournament.

That said, the PGA Championship is a single event which is often referred to as "The PGA Tournament". The PGA Championship is played at a different site in the US from year to year - although several courses have hosted the Championship more than once. Some of the courses have been private clubs while others have been public clubs. The Masters is ALWAYS played at Augusta National Golf Club, a private club. Membership at Augusta National Golf Club is strictly by invitation; there is no application process.

Both tournaments are by invitation only, but the PGA does not explicitly invite any amateurs while the Masters invites both professionals and winners of amateur tornaments. The only way for an amateur to guarantee an invitation to the PGA Championship would be to win one of the other PGA majors - i.e. the Masters, the US Open, or the Open Championship. Realistically, if an amateur were to win the British Open they would probably also garner an invitation to the PGA Championship.

Answer 2

No. The Master is one of the Four majors played on the PGA Tour (British Open, US Open, PGA, and Master's), and is open to players of all ages who have qualified either by winning an event the year of the Master or are on the leading money list in other countries and all previous Master's Champions are allowed to played. The Champions (Senior) Tour is for Players 50 and over who must qualify to play in the events on this tour..
