If the 6-foot-10 Isner he keeps serving the way he has been over the past 1-1/2 weeks, that's a real possibility.
He hit 25 aces and saved the only break point he faced against 2016 Wimbledon runner-up Raonic, and has won all 95 service games he's played across five matches.
“I didn’t have many chances,” said Raonic, who had his right thigh taped by a trainer after feeling something akin to a muscle tear in the first set.
“Wasn’t necessarily anything overly surprising. He's been quite disciplined when he’s come forward,” the 13th-seeded Raonic said. “I also saw he's been doing that much better over the last weeks and months.”
It’s the second year in a row a man from the U.S. made a breakthrough at Wimbledon. In 2017, Sam Querrey got to his first major semifinal in his 42nd attempt, the most on record.
For Isner, Wednesday’s match was only his second Grand Slam quarterfinal. The other came back in 2011 at the U.S. Open.
“Certainly the Grand Slam results haven’t been there,” said Isner, whose wife is pregnant with their first child.”"But now I'm sort of rectifying that, I think.”
Inser, winner of the 2017 BB&T Atlanta Open, will defend his title later this month at Atlantic Station.
In Friday's semifinals, he will see a friendly face across the net in No. 8 seed Kevin Anderson, a South African who saved a match point and came all the way back to stun eight-time champion Roger Federer 2-6, 6-7 (5), 7-5, 6-4, 13-11.
“He showed a lot of — what can you say? — gumption, I guess,” Isner said.
Isner leads Anderson 8-3 in head-to-head matchups on tour, but their rivalry goes back further than that. They faced each other as college players when Isner was at Georgia, and Anderson at Illinois.
“We've known each other forever,” Isner said.
