ゲリー・ウェバー・オープン
Entering the grass court season, Millman had disappointing results in the Stuttgart Open, Halle Open and Eastbourne International enduring first round exits in all three. However, he found form at Wimbledon, progressing to an equal career-best 3rd round with victories over Hugo Dellien and 31st seed Laslo Đere before falling to Sam Querrey in straight sets. At the Rogers Cup, Millman reached the second round as a lucky loser.
