Roger Federer is going for a record-extending ninth Wimbledon title this fortnight.

Five Keys To Federer's Wimbledon Domination

Infosys ATP Insights explains how the Swiss has won eight titles at SW19

Strawberries and cream are a delicious combination at Wimbledon. So is Roger Federer’s serve with the perennial rye grass that covers Centre Court like a lush carpet.

An Infosys ATP Insights deep dive into Federer's serve at The Championships from 1999 to 2018 uncovers five keys to his unprecedented success of winning eight titles at the home of tennis.

1. First Serves Made = 65.4%
Federer has made more first serves than the field over the past decade. From 2009-2018, the average for the tournament is 63.4 per cent (182,068/286,946). Federer is a full two percentage points higher than that at 65.4 per cent. Two more first serves in play out of every 100 may not seem like a big deal, but it’s a small advantage that snowballs.

2. Unreturned Serves = 4,120
More than 4,000 times Federer has sent a first or second serve barreling down at The Championships since 1999, and it has not come back. When hitting first serves, almost half have failed to make it back in the court, while around a quarter of his second serves have needed no more attention from the Swiss.

First Serves Unreturned = 48.6% (3323/6839)
Second Serves Unreturned = 23.1% 797/3443)

3. Double Faults = 173
Federer has hit 3,567 second serves at SW19, and committed only 173 double faults, which means he has hit a double fault just 4.9 per cent of the time. What does that really mean? He averages one double fault about every 20 second serves. That is way above what the rest of the field produces.

For example, there were 1,032 double faults at The Championships in 2018 out of 7,238 second serves, which means, on average, there was one double fault for every 14 second serves. Federer finds a way NOT to beat himself way better than his opponents.

4. Aces = 1,349
Federer has hit 1,311 aces from 8,839 first serves. That means he averages an ace one out of every 6.7 first serves, or around once every two service games. Federer has chipped in for 38 aces behind his second serve, which is also no mean feat.

5. 80 & 60
Federer has won 80 per cent of his first-serve points and 60 per cent of his second-serve points at Wimbledon. Both of those metrics are exactly three percentage points higher than his career average, and substantially higher than the round one statistics from Wimbledon this year.

2019 Wimbledon Round One (64/128 matches)
First-Serve Points Won = 72% (6316/8753)
Second-Serve Points Won = 52% (2682/5203)
