A look at the numbers and figures behind Juan Martin del Potro's run to the US Open semi-finals.
Juan Martin del Potro came through a tight battle with top American John Isner 6-7(5), 6-3, 7-6(4), 6-2 in sweltering conditions on Tuesday to reach the semi-finals of the US Open.
The 2009 champion fought off Isner in a 3hr 31min showdown and joked after the match about how tough it was playing through the heat.
Both players went off-court for a 10-minute break after the third set, since the extreme heat policy was in effect, and Del Potro was asked during his on-court interview what he did during that time.
“I took a shower, re-taped my ankles, and I didn’t want to come out again,” the world No. 3 said with a laugh.
He added during his press conference: “I think I played very solid this game. In particular I made good returns every service games. I had a lot of chances to break. I did couple of times during the game. I think I play on a smart game today. I saw John a little bit tired also. That’s give me a little bit more energy to keep trying.
“I played a good match. I don’t know if I’m playing my best tennis ever, but I’m feeling good. I reach another semi-finals in this Grand Slam, which means something big to me. I’m very happy for that.”
Isner, who now trails Del Potro 4-8 head-to-head, explained what makes Del Potro such a tough opponent to face.
“He’s so good, and especially when he gets control of the point, of course on his forehand side, he doesn’t miss that shot very often, if at all,” said Isner.
“He’s such a tough player and he’s playing well and he likes these conditions. He likes playing on a hard court like this. Yeah, I mean, again, when he gets control of the point, it’s very tough to wrest it back from him. Yeah, that’s what he does so well, and I think he’s exhibited that throughout this whole tournament. He’s been playing very well.”
