Weakest Seasons with 2 Majors of the Open Era

[McEnroeisanartist]

"Weakest" defined as Few Titles outside of the 2 or more Majors won in a Year:

1988 - Mats Wilander - 3 Grand Slams, only 3 other titles
1989 - Boris Becker - 2 Majors, only 3 other titles
1992 - Jim Courier - 2 Majors, only 3 other titles
1995 - Pete Sampras - 2 Majors, only 3 other titles
1999 - Andre Agassi - 2 Majors, only 3 other titles
2009 - Roger Federer - 2 Majors, only 2 other titles

If Novak wins the 2012 U.S. Open and doesn't win any other tournaments, it would be only his third title of the season, but two majors.
