(Reuters) – World number one Andy Murray started his new season with a surprise 7-6(4) 6-4 loss to David Goffin in the semi-finals of the Mubadala World Tennis Championship in Abu Dhabi on Friday. After losing the opening set at the year-ending exhibition event, Murray, twice winner of the tournament, recovered to go 3-2 up in the second set but Goffin broke back twice and held serve to progress to the final. Goffin will face either Milos Raonic or Rafael Nadal in Saturday’s final, with Murray, who lost just nine matches in his entire 2016 season, up against the loser of the semi-final.
