If this is in the wrong section feel free to move it. This is what I know...... 19 - Richard Krajicek (1998 Wimbledon SF 5th set vs Ivanisevic 13-15) 16 - Goran Ivanisevic (1994 Wimbledon F 1st set vs Sampras 6-7) 16 - Pete Sampras (2000 Aus Open SF 4th set vs Agassi 6-7) 13 - Pete Sampras (1995 Aus Open F 4th set vs Agassi 4-6) 12 - Michael Stich (1993 ATP World Champ F 4th set vs Sampras 6-2) 12 - Pete Sampras (2002 US Open F 1st set vs Agassi 6-3) 11 - Pete Sampras (1995 US Open F 4th set vs Agassi 7-5) 10 - Pete Sampras (2002 US Open F 3rd set vs Agassi 5-7) Ivanisevic, Philippoussis, Karlovic and Johansson are are going to have a few entries on this list, so if you know of any please add. Please keep it 10+ aces a set. I know Sam Querry hit 10 in a row, but don't how how many he finished the set with. Ivanisevic had 35 in 3 sets (1996 YEC SF vs Sampras) so he should be on the list again. Sampras opened his 1998 Wimbledon match vs Enqvist with 7 straight aces, and in 1995 Grand Slam Cup had 24 aces in 2 sets P. McEnroe. Roddick hit 24 in 2 sets in Cincinnati 2005 vs Hewitt, so that puts him on the list, as does his 31 aces in 4 sets vs Hewitt in 2005 Aus Open. Philippoussis had 29 in 3 sets vs Sampras in 1996 Aus Open, and 28 in 3 sets later that year vs Pete at Wimbeldon. Johansson's 51 aces (in 4 sets) effort vs Agassi puts him on the list, but I dont how many he had in a any singular set. The same with Krajicek's 49 aces (in 5 sets) vs Kafelnikov at the US Open.
