He made an uncertain start. After only dropping serve twice in the whole week – and not at all until the semifinal – the 23-year-old was broken in his first service game.
He also struggled in the next one, fending off a couple of break opportunities, and that unfortunately set the tone for the match.
Norrie, who had been so precise throughout the week, couldn't find his range and made a mountain of unforced errors in his first ATP decider. There were moments of brilliance, but not quite enough.
Norrie broke back in the first set, but was immediately broken again, and the 27-year-old American was good enough to serve out the set.
Norrie couldn't shift the momentum in the second set. He was broken twice – in one game saving three break points – and couldn't take advantage of his few opportunities on the Sandgren serve.
Norrie fought to the end, staving off a match point at 4-5 down before forcing a break point of his own. But he dragged consecutive returns wide, before Sandgren converted his second match point.
