WRONG!!!!
Agassi won 4 AO titles (rebound ace)
2 US Opens (hard court)
By the way, your list is a joke.
No dominance at any major event or in the #1 ranking for Agassi ... the closest would be the Australian Open.
Agassi has had a little success in several areas of the sport ... no, he has never won a 2nd, 3rd, 4th, 5th, 6th or all-time record 7th Wimbledon ... no, he has never won a 2nd, 3rd, 4th or all-time record 5th ATP Championship ... no, he has never finished a 2nd, 3rd, 4th, 5th or all-time 6th year ranked #1.
Agassi did manage to fluke into a lucky draw at the 1999 French Open and Sampras came up 2 matches short of this when he had to beat the top clay court champions of the Open Era from the United States and Spain in 5 set battles before the semifinals.
Sampras came within 2 matches of matching Agassi in singles titles at the French.
