MELBOURNE, Australia (AP) — Tennys Sandgren has heard all the jokes about his name. It’s reached the point where he doesn’t even use it anymore when ordering a coffee.

“I say ‘David’ or something like that. I don’t want to deal with the whole name thing … especially first thing in the morning,” Sandgren said.

With Sandgren’s upset win over former champion Stan Wawrinka in the second round of the Australian Open on Thursday night, his name is only bound to become better known. He just hopes people start talking about his actual tennis game, too.

Sandgren’s rise in the last year has been as sudden as it was unexpected. When Wawrinka was winning the 2016 U.S. Open, Sandgren remembers watching it on television while having beers at a bar. His ranking was No. 263 and he’d lost a couple weeks earlier in the first round of U.S. Open qualifying.

“I tried to put myself in those guys’ shoes, like what would that take, and could I ever play at a level like that?” he said.

Then, in early 2017, the Tennessee native started to find out. He won two tournaments on the lower-tier Challenger Tour and reached the final of another, earning him a wild card spot in the main draw at the French Open — his first Grand Slam event.

Sandgren lost in the first round at Roland Garros, but the results kept coming. Last summer, he notched a win over Nick Kyrgios when the Australian retired in their second-round match at Washington and cracked the top 100 for the first time.

Now, the No. 97 Sandgren has earned by far the biggest win of his career over the ninth-seeded Wawrinka, whom he beat 6-2, 6-1, 6-4, and is into the third round of the Australian Open — his best result…
