Victory gave the fifth-seeded American his third ATP tour title but first on grass, with Queen's long one of the leading warm-up events for Wimbledon.

The 27-year-old raced through the first set of this 88-minute encounter before Italian opponent Musetti worked his way back into the match.

Paul failed to serve out the match at 5-4 up in the second set. He then came from 1-4 down in the tie-break and saved a set-point at 6-7 before taking the title.
