Britain's Gordon Reid missed the chance to finish 2016 on a winning note as he lost in the final of the NEC Wheelchair Tennis Masters in London.
The 25-year-old Scot was beaten 4-6 6-4 6-4 by defending champion Joachim Gerard of Belgium at the Olympic Park.
However, the 2016 Rio Paralympic champion still finishes the year as men's singles world number one.
"That was a really disappointing performance. My serve and return let me down a bit," Reid told BBC Sport.
"They were my two biggest strengths over the week and they are important on this surface and were the two things I did the worst today.
