Obviously, John's service game was outstanding again.
Louk's serve was surprisingly good despite his 5'9 height disadvantage. I was impressed with how easily Louk held his own serve and how many aces and unreturnable serves he also had. Also, Louk doesn't hit many unforced errors and John really had to earn his points when he wasn't serving. These match stats are pretty revealing for both players:
Just about a 2:1 winner to unforced error ratio for Louk if you add the aces to the winners.
You can also see how close the match was (99 pts to 94).
Louk did lose his serve after scraping his leg in the 5-5 game in the third set when he had two break points to serve out the set. It seemed to take him out of rhythm on his next service game, and it was the only bad service game I witnessed today. He had some brilliant winners and played a solid match today.
The 70 extra points should improve his ranking to a career high, somewhere around #205. With a few more results like this he could break into the top 200 and set his sights on the top 100. Isner was very complimentary of Louk's efforts and it was nice to see him get some major television coverage and exposure. He handled the big stage pretty well.
One obvious complaint, Louk needs to play the big points a little better. He had a couple of bad misses at the net that could have turned the whole match around in his favor, but flubbed them. Unfortunately, this included the match point. Total points won was extremely close, only 5 points in Isner's favor. That margin is not usually indicative of a 3 straight set victory.
