I have a copy on DVD and recall that the quality of play was very high. Just didn't remember if it was semis or final.
Agassi played very well. He came to the net a lot and with much success. He just wasn't fit enough to maintain the high level of play into the fifth set.
Wilander was very good in 1988. Just ask Ivan Lendl. Lendl beat Agassi in the US Open semis in four sets (dropped the first set to a red-hot Agassi) only to be out-played by Wilander in an excellent final.
Wilander was very fit, and he just made so few errors from the baseline or at net. Very smart, very stingy player in '88.
