Jack Sock's 2017 had everything: a Hopman Cup final, a title in Auckland, a walkover tournament win in Delray Beach, deep runs during the Sunshine Double, a whole lot of losing and then:
Moment of the Year
Sock took advantage of a depleted Paris ATP Masters draw to win the tournament and make an improbable run to the ATP Finals. In the second round in Paris, while ranked No. 22, he fell behind 1-5 in the third set to Kyle Edmund. He turned the set around to win it in a tiebreak, and went on to win the tournament.
Once he got to London, Sock beat both Alexander Zverev and Marin Cilic to become the first American to make the semifinals of the year-end championships since Andy Roddick in 2007
Hot Shot of the Year
Why hit a backhand volley when you can just go for a forehand behind your back?
