That's interesting from Tignor, but one wonders how he could observe both matches at the same time since they were played simultaneously. From reading the piece, I don't think he was at Raonic's match -- at least not more than momentarily.
It was interesting to read what Raonic said about not cranking his first serve. What we saw were mainly serves in the 130 range. Raonic's forehand was working some magic. But, he did boom one at 148. It came out of nowhere, and didn't even seem that fast, but then 148 popped up on the board and the crowd ooohhhhhhhed.
He made a rookie mistake in the second. He was cruising to the win and only had to break Ilhan again. Ilhan stiffened. He's a competitor too. Raonic lost focus. That's the only thing that can account for that sloppy game. So, someone once said that everyone loses focus somewhere during a match. It's not possible to concentrate 100%. The great ones get focus back after maybe a point or two, and that's the difference -- how quickly do you regain concentration? Raonic, unfortunately, did not regain concentration quickly enough. Ilhan had gotten some confidence back by holding and Raonic had mentally already won the match and had let up. So he got broken. Hope he learned a lesson.
I left before the tiebreak. I had another match to go see and didn't want to get held up on Court 2.
