DELRAY BEACH, Fla. — After securing his second berth in a final this year, Jack Sock took a brief break in the locker room, stopping only to change his socks. He shed the neon-orange ones that matched his equally blinding orange sneakers and went for bland white. The sneakers remained the same.
Sock had just completed a 6-4, 7-6 (2) semifinal win over his fellow American Donald Young on Saturday to reach the championship match of the Delray Beach Open, but neither he nor his traveling coach, Troy Hahn, was particularly thrilled with his performance.
