Two men have reached the third round without losing serve: Roger Federer and Milos Raonic. 

Federer has reached the final at Wimbledon for the last two years, dropping serve just once in each year. Raonic leads the ATP Tour in 2016, holding 90% of his service games. These are two very dangerous servers who look to be serving notice to the rest of the field.
