Isner may not be the best overall player without a Masters title, but he has performed better in these events than nearly any other player who has not captured a title.
"As always, I have been feeling tight in all my body for the last couple of weeks, but when I get into the court I love to play tennis", del Potro said.
Raonic will take on Del Potro (Picture: USA TODAY Sports) Will Del Potro keep his win streak intact? "He was too good for me".
"When he plays like that, he's one of the toughest guys on tour to beat", Del Potro said.
Raonic took the lead by winning the first set, but the Argentinean made a comeback and won two sets in a row. The American won 80 per cent of points on serve, claiming an astonishing 75 per cent of second-serve points against arguably the most in-form player in the world. "I also think he has a big potential to reach the final here, so it's going to be a hard challenge to me". He plays every time making winners.
"I think I missed more shots today than I did in the whole tournament", he said.
"I mean, look, it's going to be a completely different match", Zverev predicted. His semi-final result was not for lack of effort. "Zverev is a big server like Isner, but standing 4 inches shorter than the 6'10" Isner, plays a fairly different game.
"I was just ready for this moment", he said. "He was better than me, and he deserved to win".
A year ago, Zverev eliminated Isner from the Miami Open in the Round of 16, but Zverev says that has little bearing on Sunday's meeting. The string of victories on Key Biscayne surprised even him because he arrived with a record of 1-6 this year, including losses to players with rankings of 60, 62, 78 and 91.
Many readers may be surprised at this, because on the surface, three head-to-head wins in the last 18 months would appear to be pretty relevant, but upon closer examination, it is very evident that Zverev was not as dominant in these matches as the scorelines would have you believe. He then recovered from a poor start to defeat former world #3 David Ferrer in three sets 2-6 6-2 6-4. But the Argentine has announced loudly and clearly that he is once again a tremendous force to be reckoned with on the ATP World Tour. "I knew I had to focus on my side of the court and be exclusively focused on myself". The 20-year-old hit 42 unforced errors in an effort to blow Svitolina off the court, but offset that with an impressive 44 winners.
