Sam Querrey continues to play seed exterminator on Wimbledon's lawn.

The 65th-ranked Querrey toppled Roland Garros runner-up Dominic Thiem, 6-7 (4), 7-6 (1), 6-3, 6-0, to roar into the Wimbledon second round for the ninth time.

Though Thiem is ranked 61 spots higher, Querrey has won 51 more grass-court matches in his career than the Austrian, who struggles to return serve on lawn.

Querrey cracked 22 aces, denied all six break points he faced and permitted just seven points on first serve in a two hour, 29-minute conquest, denying Thiem his 250th Tour-level victory.

A framed shot from Querrey fell in right in front of the baseline, rattling Thiem in the second set. That funky shot helped spark the American.

"The second set I played one breakpoint too defensive," Thiem said. "I really go for it on the second. He frames it in like right before the line. That was, of course, little bit tough to handle.

"I mean, I played a pretty bad tiebreak. I started the third set okay. I was serving really good. Then 3-All, what I said, I had again this break chance where I should make this return because I had it clean on the racquet. Of course, it hit me a little bit that he converted his first break chance.

"After that, he was on fire. Was really tough to come back."

The fifth-seeded Thiem is the fourth Top-20 seed to fall at the first hurdle, joining No. 6-seeded Alexander Zverev, No. 7-seeded Stefanos Tsitsipas and 16th-seeded Gael Monfils in bowing out in the opening round.

Querrey, who toppled Andy Murray en route to the 2017 Wimbledon semifinals, said he felt the pressure was on the two-time Roland Garros runner-up.

"Playing Dominic, you want to say you treat every guy the same but you don't," Querrey said. "He is ranked five in the world and seeded here and had a great run at the French.

"I know grass is not his preferred surface but I felt the pressure is on him."

Next up for Querrey is a second-round match against either Andrey Rublev or Cristian Garin.

Meanwhile, Thiem suffered his third opening round exit in six career appearances at The Championships. Thiem's expansive backswings can create timing issues on the lower-bouncing lawn and he's been a victim of his own clay-success as going deep in the Roland Garros draw in recent years left him little preparation for grass.

"All the clay court season it takes a lot out of me," Thiem admitted. "I gave everything what I had physically and also mentally in all these six weeks until the end of the French Open. Then I had to take the decision to come here without any preparation.

"Of course, it's very tough to face Querrey, who loves grass, to face him in the first official grass court match for me of the year. It's a lot of experience also. I'll see how I do it next year. I mean, I like to play on grass. Of course, I would love to do better here especially than I did the previous like last year and this year. With playing that deep in the French Open, it's a tricky situation."
