Forgive me for quoting my own post, but the main AO thread is closed, and I didn't think it my place to post this in the Fed Fans thread. I was thinking more about this today, and wondering if it isn't part of why Tsitsipas upset Roger. I know some fans said he played poorly. He didn't convert any BPs. But, Roger looked like he was about to go up 2-0 in sets when I went to bed. I thought he had that match. A reason that fans get so mad at up-and-comers pulling off the upset is that they sort of have "nothing to lose," and throw it all at the more top guy. (Which is why they often fail to back it up in the next round.) Roger, as defending champ, would have been timing his performances to peak later in the second week. Obviously, he hasn't been in the best patch of form, and he ran into someone who was more than just a random comer. But I wonder if he wasn't holding a bit back in part of that match, keeping his powder dry for later, when the Greek did really have nothing to lose, or no way of knowing how to think like that...meaning saving it for later rounds. For him, it was beat Roger or go home. I'm just suggesting that the elite players time their tournaments differently, believing that they showed up to be there on the last Sunday. But someone can sneak up on you that way. I dunno. Just a thought.
