This one has come up before because the published stats are a little confusing. I've got my own stats below and the boxscore. Sampras d. Moya 6-2, 6-3, 6-3 Sampras had 24 clean winners apart from serves: 10 FH, 1 BH, 6 FHV, 5 BHV, 2 overheads. Moya had 10 clean winners apart from serves: 7 FH, 3 BH. Sampras had 12 aces and 18 other unreturned serves, 2 of which I judged as service winners. Moya had 2 aces and 21 other unreturned serves, 1 of which I judged as a service winner. LA Times: I have Sampras at 11 volley winners, not including 2 overheads. I’ve got him at 38 total winners if I include his 12 aces and the two service winners I gave him. And I’ve got Moya at 13 total winners if I include his 2 aces and the one service winner I gave him. Daily Telegraph (Sydney): Again, including my judgment calls I've got Sampras at 14 "service winners" and Moya at 3, with the term understood here to include aces. The Telegraph (UK): In the opening game Moya did have an ace and three other unreturned serves; here those serves are casually referred to as service winners, though I didn’t judge any of them to be more than ordinary unreturned serves. New York Times: The Age (Melbourne): THE MEN'S FINAL Sampras Moya 1st serve % 72% 63% Aces 12 2 Double faults 2 3 % won on 1st serve 82% 58% % won on 2nd serve 53% 41% Winners 38 13 Unforced errors 22 18 Break-point conversions 100% 50% Net approaches 80% 20% Total points won 89 59 Match time: 1hr 27mins (sets 23, 28, 36) (The ATP has higher figures for Total Points Won because they counted the aces and df's twice). Note to 380: I think in this match when Sampras is credited with 14 "service winners", and Moya with 3, the term includes aces -- something I think also happened around this time with NBC in the 1998 W final and CBS in the 2005 USO final. When we debated this before I think both of us had assumed that Pete's 14 service winners were separate from his 12 aces, and technically that's possible; there are enough unreturned serves to fit them in. But if that happened, there are a few problems. For one, I don't see why 14 of Sampras' serves would be judged as service winners, while Moya would be credited with only 3. If you look at my count, Moya actually drew more return errors than Sampras did. Yet he gets only 3 winners on those serves while Sampras gets 14? There is no difference in how those serves looked, at least none that I could judge. The substantial difference between the two men was in the aces. Including them would explain why Sampras had so many more "service winners" than Moya. Also, if the service winners and aces are separate, Sampras stands at 36 winners overall (12 aces, 24 volleys and groundstrokes). To get him to 38, someone still has to give him two more judgment calls, as I did. So rather than assume that someone gave him two judgments while someone else gave him 14, I think it's simpler to read the service winners as including aces -- particularly because my judgment calls line up precisely with the totals. Now, this is different from an older match like the 1990 USO final. That boxscore did not combine the category of service with the other winners. It just reports placement winners on the one hand and service winners and aces on the other. And in that boxscore, the "service winners" are separate from the aces. As you wrote once, we know mathematically that Sampras' 12 service winners in that boxscore can't include his 13 aces. Sometimes in older matches you find the service winners explicitly described as separate from the aces, for example the 1986 W final: "Becker laid the strong hand of his service game on Lendl, 15 aces and 23 other service winners" (Atlanta Journal Constitution). But whenever the reported "service winners" are higher than the aces I think you'd have to consider the possibility that they include the aces. The Sampras-Moya service winners are mostly aces, next to just a few judgment calls. But most stats that I see nowadays are done similarly. Anyway that's my best explanation.
