From watching today's match streamed, Phil seemed tired today, likely from his run at Granby. He didn't have command of his forehand in particular (tired wrist, elbow, and shoulder will do that). Too bad he used up a PR
, but he wouldn't've known he'd make his run when he scheduled, and with a slightly better draw, Sandgren is solid, he could have survived today and then gotten over his fatigue. He was up 5-2 in the first set too, but couldn't close - I doubt it would've mattered though.
