Federer comes into the season-ending championship as the tournament favourite and will be hoping to cap off his stellar year with a 7th Tour Finals title.
The world number 2 has a 3-0 career lead over Jack Sock in head-to-head meetings, the most recent of which was a 6-1, 7-6 (7-4) victory over the American in Indian Wells in March.
The 19-time Grand Slam winner has been dominant on serve throughout 2017, winning 90% of service games on hard courts so as always he will look to dominate in that department.
Jack Sock has enjoyed the best season of his career and is carrying form and confidence after winning his first Masters 1000 title earlier this month in Paris.
That win propelled him into the world's top 10 for the first time and gave him passage into this tournament so he knows he is in the best shape possible to test Federer in this opener.
The American has won 83% of service games on hard courts this year and he knows that area of his game must be on point if he is to have any success here.
Roger Federer has a 100% win ratio when playing Jack Sock having beaten him on three previous occasions.
Roger Federer won all three group matches in the last two ATP World Tour Finals that he has played in 2014 and 2015.
Roger Federer has beaten Jack Sock in straight sets on all three occasions that they have met.
Jack Sock has won four career titles and three of those have come in 2017.
Roger Federer's win ratio in 2017 to date is 92.5% compared to Jack Sock's 65.5% this season.

Federer is fully-focused on capping off his fairy-tale 2017 with victory at the ATP World Tour Finals - unofficially dubbed 'the fifth major'. Sunday's meeting with Sock will not be straightforward as the American won in Paris recently and is playing some of the best tennis of his career, but having failed to take a set off Federer in three previous meetings (all on hard court), the Swiss has to be considered a firm favourite in this tournament opener.
