by International Tennis Hall Of Fame/Hall Of Fame Open

John Isner said he’s “nowhere near” in the shape he wants or needs to be as he works his way back from a broken foot. The No. 1 seed at the Hall of Fame Open, however, was able to grind out a victory against Kamil Majchrzak of Poland on Wednesday.

Isner will face Matthew Ebden of Australia in the quarterfinals on Friday. Isner is 4-1 in his career against Ebden, whose only win in the series came at last year’s Australian Open.

“It wasn’t easy. The conditions were brutal — it’s windy and like 90 percent humidity — but I’m happy to claw through that, because it wasn’t pretty at times,” Isner said of his victory. “Movement isn’t the best part of my game, but when I’m at my best, I’m at least able to play some defense and I don’t feel like I’m able to do that right now.”

As he always does, Isner relied on his offense, serving 25 aces and saving all five break points he faced.

Isner said he is pain free after breaking his left foot in Miami in March, but aside from fitness, his biggest issue in the comeback is on the mental side.

“It’s more of a confidence thing, because for so long, my foot was just hurting,” he said. “I was scared for the longest time to do anything. When I finally got the OK to practice, I was still scared to move and try to cut. I’m just trying to get confidence in my foot.”
