since roddick never advanced past 4R at roland garros, we can leave that out (enough to say sampras has better stat at rg, 82.9% against 81.7% for roddick)

i got some really interesting results, here they are;

australian open


sampras 89.3%
roddick 90.5%

R1 to R4

sampras 90.1%
roddick 93.1%

QF to F

sampras 87.6%
roddick 82.3%



sampras 94.1%
roddick 93.4%

R1 to R4

sampras 94.2%
roddick 94.6%

QF to F

sampras 94%
roddick 90.2%

us open


sampras 91.6%
roddick 91%

R1 to R4

sampras 92.3%
roddick 93%

QF to F

sampras 90.2%
roddick 84.8%

- so roddick leads in their total at AO, and is only slightly behind at USO and W

- roddick leads at all 3 slams in first 4 rounds, even at wimbledon, and is quite better at AO

- sampras leads huge at all 3 slams from QF to F

i'll let you draw the conclusions, can't write anymore
The numbers you cite are indirect measures of the serve and are confounded by the other factors that affect service holds (ie, strength of ground game). They suggest Sampras is a better player, but do not really prove anything about the serve.

The stats that are most important for assessing the serve as a stroke are
- Aces
- Winners
- 1st serve %
- Double faults
