Stick with you on this one. CAn someone analyse what a miracle has to happen in order for fed to pick up another USO and nadal to finish at nr1 ? Especailly now, hard court competition is getting better, tennis is a fun sport now compared to record breaking, boaring but yet must watch federer 2006 display of dominance.
Easy enough. This is Federer's current points break down:
Masters Cup
13-Nov-06 Tennis Masters Cup China W 750
Slams
25-Jun-07 Wimbledon Great Britain W 1000
15-Jan-07 Australian Open Australia W 1000
28-Aug-06 US Open NY, U.S.A. W 1000
28-May-07 Roland Garros France F 700
Masters
13-Aug-07 ATP Masters Series Cincinnati OH, U.S.A. W 500
14-May-07 ATP Masters Series Hamburg Germany W 500
16-Oct-06 ATP Masters Series Madrid Spain W 500
5-Aug-07 ATP Masters Series Canada Montreal, Canada F 350
15-Apr-07 ATP Masters Series Monte Carlo Monaco F 350
7-May-07 ATP Masters Series Rome Italy R16 75
19-Mar-07 ATP Masters Series Miami FL, U.S.A. R16 75
5-Mar-07 ATP Masters Series Indian Wells CA, U.S.A. R64 5
30-Oct-06 ATP Masters Series Paris France - 0
Best Five others:
26-Feb-07 Dubai U.A.E. W 300
23-Oct-06 Basel Switzerland W 250
2-Oct-06 Tokyo Japan W 250
Total: 7605
So assume that Federer wins the US Open but does not participate or loses the first round of any further events he enters, he'll have 5700 (slams) + 1855 (masters) + 300 (other) = 7855
-------------
Now Nadal's current points:
Masters Cup
13-Nov-06 Tennis Masters Cup China S 200
Slams
28-May-07 Roland Garros France W 1000
25-Jun-07 Wimbledon Great Britain F 700
15-Jan-07 Australian Open Australia Q 250
28-Aug-06 US Open NY, U.S.A. Q 250
Masters
7-May-07 ATP Masters Series Rome Italy W 500
15-Apr-07 ATP Masters Series Monte Carlo Monaco W 500
5-Mar-07 ATP Masters Series Indian Wells CA, U.S.A. W 500
14-May-07 ATP Masters Series Hamburg Germany F 350
5-Aug-07 ATP Masters Series Canada Montreal, Canada S 225
19-Mar-07 ATP Masters Series Miami FL, U.S.A. Q 125
16-Oct-06 ATP Masters Series Madrid Spain Q 125
13-Aug-07 ATP Masters Series Cincinnati OH, U.S.A. R32 5
30-Oct-06 ATP Masters Series Paris France - 0
Best Five Other
23-Apr-07 Barcelona Spain W 300
16-Jul-07 Stuttgart Germany W 250
26-Feb-07 Dubai U.A.E. Q 75
1-Jan-07 Chennai India S 75
11-Jun-07 London / Queen's Club Great Britain Q 55
Total: 5485
So his current points not counting what he has to defend: 4910
Now let's add 700 for a final showing in US Open, 1000 for wins in Madrid and Paris and 750 for the Master's Cup. Now in his best five let's substitute Dubai, Chennia and London with wins in say, Moscow, St. Petersburg and Basel for 250 each (750 total).
Final totals in our hypothetical:
Federer: 7855
Nadal: 7905
Basically, it's possible but EXTREMELY unlikely to happen. Nadal will literally have to win two masters, the masters cup and three top tier events
and Federer would have to not play after winning the US Open. What are the odds?
