Isner, ranked 16th, fired 10 aces, the last of them on the penultimate point, in defeating Belgian eighth seed Xavier Malisse 7-6 (10/8), 6-2 in a match that lasted just 68 minutes.
World number 22 Haas, who ousted US wild card Steve Johnson 6-4, 6-2, has lost three of four career meetings to Isner.
Haas was last year’s ATP comeback player of the year after an injury-nagged 2011.
But they have not faced each other since a second-round match at Cincinnati in 2009.
