Dylan Alcott sealed a place in the US Open quad singles final after a straight-sets win over long-time rival David Wagner on Saturday.

Alcott’s 6-0 7-6(3) win over Wagner saw the Australian go undefeated in three round-robin matches this week at Flushing Meadows.

He will take on Andy Lapthorne in the final, who was the second-best performer in the round-robin stage of the event.

Alcott will be aiming for an historic calendar-year Grand Slam after scooping the Australian Open, Roland Garros and Wimbledon titles earlier in 2019.

Lapthorne, whom Alcott thumped for the loss of just two games in the Wimbledon final, was far more competitive in their US Open round-robin match on Friday, earning four match points before eventually going down 0-6 7-6(3) 6-3.

With that win, and his victory over Wagner, Alcott remains unbeaten in 2019 — in both singles and doubles — and extends his singles winning streak to 23 matches.

Alcott and Lapthorne will play their final in the first match of Sunday’s schedule on Court 17, before combining later in the day for the doubles final against Wagner and Bryan Barten.
