Watch List: Bonjour Paris; London scenarios

Last chance for glory: It's the last tournament of the regular season for the ATP, which means any attempt to predict what will happen is a futile endeavor. Heck, we don't even know who's going to be playing! Rafael Nadal has already withdrawn from the Paris Masters and Juan Martin del Potro announced his withdrawal over the weekend, citing a shoulder injury.
But all eyes are on Novak Djokovic, who lost only his fourth match of the year, to Kei Nishikori, on Saturday, and seems to have picked up a right shoulder injury. No one would begrudge him a decision to skip Paris (well, except maybe the tournament director and ticket-buying fans). He's already locked up the year-end No. 1 ranking and doesn't want to carry an injury into the ATP World Tour Finals in London.
So with most of the players either limping, streaking or slumping, it will be interesting to see who's still vested and who's already checked out into the offseason.
Last gasp for London: We know that at least five men are still vested (six if you count Gael Monfils, who still has a long-shot chance), as they try to clinch their place in the World Tour Finals. Three spots remain open going into Paris, with Tomas Berdych, Jo-Wilfried Tsonga and Mardy Fish in pole position. With a more than 500-point lead on the remaining contenders, their spots are safe so long as they post better results than Nicolas Almagro, Janko Tipsarevic and Gilles Simon -- who would have to make the finals to even have a chance.
Here are the updated point scenarios for the final three spots:
Follow-up Federer: Roger Federer won his first title in 10 months in Basel, Switzerland, over the weekend, and don't be surprised if he runs the table through Paris and London. That said, anything can happen on these quick courts. Federer has never won in Paris and he has Richard Gasquet and Fish to contend with in his quarter (both of whom could either crash out or contend), and he's been drawn into Andy Murray's half. Federer looked to have shaken off any rust in Basel and seems motivated to make a strong push through the end of the season. That's bad news for the beleaguered and depleted field.
Gluteus-free: Leave it to Murray to suffer one of the more bizarre injuries in recent memory. The Scot was fine as he practiced in advance of last week's tournament in Basel, only to go to bed and wake up with a broken butt (strained glute) that forced him to withdraw from the tournament. He seems to be fine now, arriving to Paris early in the week to resume training.
