Night match delayed, as heat/rain/lightning play havoc with schedule. Five of the serious contenders in the top half should complete their matches: Nadal, Tsonga and Federer are done; Monfils is on court against Sock; and Murray is the night match. Young and Nishikori are also through. But no one in JMDP's section will have finished, and no one else in Mr Murray's section. Potentially gives quite an advantage to all the main contenders except del Potro (though wouldn't be surprised if his match got stuck on Hisense if Monfils/Sock finishes early enough) ... bit rough on the others.
