LONDON — Andy Murray was struggling, both with his serve and his hair.
He gave himself a little trim during a changeover in the first set, but on the court he found it difficult to improve.
Taking advantage of it all was Rafael Nadal, who ended up with a 6-4, 6-1 win Wednesday for his second straight victory at the season-ending ATP finals.
Murray and Nadal traded breaks to open the match, and then Nadal held to make it 2-1. During the changeover, the second-seeded Murray pulled out a pair of scissors and clipped off a few strands of hair.
