DALLAS, Feb. 12, 2022 – No. 2 seed Reilly Opelka and No. 4 seed Jenson Brooksby each won their semifinal matches on Saturday in an incredible day of competitive tennis, setting up the final match of the inaugural Dallas Open on Sunday, set for 1 p.m.
Opelka defeated No. 3 seed John Isner, 7-6(7), 7-6(22), highlighted by an incredible second-set tiebreak – the longest in ATP Tour history with 46 points combined, an ultimate 24-22 decision for Opelka. Isner and Opelka also stretched their head-to-head current streak of consecutive sets going to tiebreak to 12. Today’s match featured 60 total aces, 39 by Opelka – an ATP record for aces in two sets, dating back to 1991.
The previous ATP record for longest singles tiebreak was 20-18, which occurred seven times.
“It was bizarre,” Opelka said of the tiebreak. “It’s just next point, you know, back to the guessing game. I have to take care of what I do and hopefully guess right, and I did. I guessed wrong a lot, obviously, and [Isner] was in more points than I was. I really hit some big shots. I stayed tough. I also served extremely well.”
The energy in the Styslinger/Altec Tennis Complex on the campus of SMU was palpable, with a large contingent of the fans rooting for Isner, a Dallas resident.
“The crowd was definitely behind me,” said Isner. “It’s kind of extra disappointing to not be able to get over the line in my backyard. That match was two guys serving big. [Opelka] is serving just massive. I don’t think anyone can break him out there.
“If I win that match there’s a good chance I win this tournament. Reilly is going to be tough to beat tomorrow, that’s for sure.”
The 21-year-old Brooksby, ranked No. 54 in the world, saved four match points in the third set to defeat No. 7 seed Marcos Giron in the second semifinal of the day, 6-4, 6-7(4), 7-6(5). Brooksby rallied in the third set tiebreaker after appearing to lose momentum in dropping the second set, also in a tiebreak. He ended up saving six-of-eight break points, which were key in the win.
Brooksby is projected to break into the ATP top-50 rankings on Monday.
In semifinal doubles, Great Britain’s Lloyd Glasspool and Finland’s Harri Heliovaara defeated Isner and fellow American Jack Sock, 6-7(4), 7-5, 10-8.
Glasspool and Heliovaara advance to the doubles final on Sunday afternoon, where they will face top seeds Marcelo Arevalo and Jean-Julien Rojer, who defeated the American duo of Sam Querrey and Jackson Winthrow in the other doubles semifinal, 7-5, 7-6(4). Sunday’s doubles final match will take place after the singles final match.
Doors open for Sunday’s final session at 12 p.m., with the singles final at 1 p.m., followed by the doubles final.
