Dimitrov may have to work hard to dismiss Sock
Goffin capable of making Federer pull out the stops

Dimitrov v Sock 2pm
Grigor Dimitrov has arguably played some of the best tennis of his career in the ATP Finals, to the delight of those who followed the pre-tournament advice of Racing Post's Aaron Ashley to back the Bulgarian each-way.
A repeat of the form Dimitrov has been producing could well see him reach the final at the expense of Jack Sock, but the Paris Masters champion has been digging deep in London and it could pay to expect another brave show from the American.
The afternoon semi-final could be long and punters could find a spot of value in backing over 22.5 games.

Federer v Goffin 8pm
David Goffin played a stinker when winning only two games in defeat to Grigor Dimitrov, but the Belgian was back on track when ousting Dominic Thiem 6-4 6-1 in his final round-robin outing on Friday.
At his best Goffin could be one of the performers capable of troubling the top brass and it may be worth backing him to win at least a set against Roger Federer on Saturday.
Federer is just 4-11 to take the title, but while he is the likeliest champion the Swiss legend may still have to toil in his bid to go all the way.
