There's a heavyweight clash to savour at the World Tour Finals on Saturday, as Roger Federer takes on Juan Martin Del Potro. Tennis expert Sean Calvert talks us through the best bets..
"With Del Potro needing a win to qualify for the last four the value has to be with him.."
Andy Murray didn't let me down on Friday, bringing home my recommended bet of the day by defeating Jo-Wilfried Tsonga in straight sets.
It wasn't without a little stress though, as the Scot let slip a 6-2, 4-2 lead to eventually take it on the tie breaker, but it was good enough.
Saturday sees the semi final lines up complete, with the deciding matches in Group A being played today and first up is Roger Federer v Juan Martin Del Potro at 1.45pm UK time.
Delpo is 3-13 lifetime against the Swiss maestro, but he did beat Federer on his home turf in Basel a few weeks ago and probably should have beaten him on the Argentine's least favoured surface of grass at the Olympics as well.
He was also in command in their match on clay at the French Open this summer before injury took hold of him, so this shouldn't be straightforward for the world number two.
Delpo did manage a win over today's opponent here at the O2 in 2009 and with him needing a win to qualify for the last four the value has to be with him at around 2.982/1.
The qualification scenario is simple for Delpo today - if he wins this match he qualifies for the semi finals, so his motivation should be high.
Both players have displayed some patchy form here in London so far this week, but I expect them to take it up a notch today and there could be some value in siding with a three set match at a price of 2.546/4 if you fancy Federer but don't like the 1.51/2 about him in the match odds market.
The overs is also a possibility or even the Del Potro 2-1 win at 6.411/2 has appeal if you're after a bigger priced wager today.
Back Del Potro to beat Federer at 2.982/1
