Alexander Blockx was the reigning champion, but was no longer eligible to participate in junior events. He received a wild card into the men's singles qualifying, where he lost to Zachary Svajda in the first round.

Cruz Hewitt, the son of two-time major champion and former ATP world no. 1 Lleyton Hewitt, and Jagger Leach, the son of three-time major champion and former WTA world no. 1 Lindsay Davenport, made their junior major debuts in this tournament.
