Charl Schwartzel of South Africa has told golf officials he will skip the Olympics.

The former Masters champion is the second South African in the last week to pull out of this summer's Rio de Janeiro Games. Louis Oosthuizen cited family and scheduling issues.

Adam Scott and Vijay Singh previously said they won't be playing. That's four major champions who already have withdrawn as golf returns to the Olympics for the first time since 1904.

PGA Tour spokesman Ty Votaw says Schwartzel informed golf officials last week. Schwartzel was a strong candidate to make the team once Oosthuizen withdrew. That means Jaco Van Zyl would be next in line for South Africa.
