British number one Andy Murray overcame Jo-Wilfried Tsonga to reach the last four at the ATP World Tour Finals this evening.
The Scot began the match needing to win just one set in order to progress beyond the round robin stage - and he achieved that goal by taking the opener 6-2.
Murray then continued his dominance by breaking serve again at the start of the second set.
Tsonga fought back and forced a tie-break, but Murray comfortably sealed victory 7-3 in the breaker.
Murray will face Roger Federer in the semi-finals on Sunday, unless the world number one loses to Juan Martin del Potro in straight sets tomorrow.
