Federer was tested by Sock in the tournament opener but ultimately came through and claimed what was his 50th tour victory in 2017.
Federer is an even bigger favourite for the title now that Nadal has withdrawn from the competition, but Zverev is now arguably the biggest obstacle in his way.
The Swiss has found Zverev a difficult opponent in the past and will need to be at his best if he is to claim a first hard court victory over the German youngster.
Zverev showed his fighting qualities against Marin Cilic on Sunday to bounce back from being 3-1 down in the deciding set to win on his competition debut.
The German is one of the few players to have beaten Federer this year and that was on a hard court in the Canadian Open final so he is more than capable of victory.
His performance on the big points has been notably impressive this season, and he edges Federer on both break points converted (45% vs 42%) and beak points saved (68% vs 66%) on hard courts.
Roger Federer and Alexander Zverev have met on four occasions with each player winning two matches apiece.
Three of the four matches between the two players have been won in straight sets.
The player winning the first set in the four matches played between these two players has gone on to win the match.
There has been only one tiebreak in nine sets played between the two players.
They have met only once on a hard court and Zverev emerged victorious in the final of the ATP World Tour Masters 1000 in Canada earlier this year.
Roger Federer has only lost four of his 54 matches played in 2017.
In one of the most intriguing match-ups of the round-robin stage, Federer and Zverev meet for the third time this season after sharing the first two encounters. The German youngster now represents Federer's biggest threat for the title and will provide a stern test for the six-time champion, but the Swiss maestro remains the man to beat and is expected to secure qualification from the group here.
