Our thoughts on what to watch and who might, maybe, could possibly win where on day six...
David Ferrer (ESP)  vs. Andy Roddick (USA) : Can you believe that this is a third round match? I can't. Both men are on a seven-match win streak on grass, with Roddick on a nice turnaround after going through a six-match losing streak after he beat Roger Federer at the Sony Ericsson Open in Miami in the spring. But can the 2009 finalist get past Ferrer, one of the most respected men in the locker room for his tenacity and competitive spirit? Roddick will need to serve well and amp up his aggression to really take it to the Spaniard. If Roddick gets stuck behind the baseline too much, he's in a load of trouble. Ferrer is not a guy who gives away the easy error.
Pick: Ferrer in four sets.
Did you know... Ferrer is the last Spaniard standing? When's the last time we've been able to say that at a Grand Slam?
Serena Williams (USA)  vs. Jie Zheng (CHN) : There's an air of desperation around Serena at this year's tournament and I suspect that she's beginning to feel a sense of urgency when it comes to when she might win another Slam title. She's done everything she's needed to do over the past year to get herself into shape and play lead-up events to prepare for Slams, yet she still hasn't won a major title since Wimbledon in 2010. Zheng reached the semi-finals here in 2008 and has the flat-hitting game that does damage on grass. Serena has never lost to Zheng and I don't expect her to do so today, but if Serena's off the boil, Zheng could cause some problems.
Pick: Serena in two sets.
Marcos Baghdatis (CYP) vs. Andy Murray (GBR) : The last time these two met at Wimbledon, Baghdatis beat Murray on his way to the semi-finals in 2006. Both men are markedly different players now than they were then, but we all know that Baghdatis has the talent and charismatic game that can beat almost anyone on any given day. The question here is whether he can tap into it when these two take Centre Court later today. I suspect Andy's focus and constency will carry the day. The only question left is whether or not Judy Murray will blow out Ivan Lendl's other ear drum with her support.
Pick: Murray in three sets.
Did you know... Baghdatis' current coach is Miles Maclagan, who was Andy Murray's long-time coach and friend. Well, they might still be friends. I don't want to start any rumours here.
Kei Nishikori (JPN) vs. Juan Martin del Potro (ARG) : Nishikori is the first Japanese man into the third round at Wimbledon since 1995 and he's bidding to become just the second one to make the fourth round in the Open Era. Can he do it? Not likely. Del Potro's power is a lot to absorb and Nishikori is just now coming back from an abdominal injury that has kept him sidelined since April. Big ask for Special Kei, but he did beat Jo-Wilfried Tsonga in Melbourne, his last win over a top 10 player. Does he have another one in him?
Pick: Del Potro in three sets.
Did you know... Del Potro has lost his last three five-set matches. Nishikori has won his last five five-set matches. So if this goes five...
David Goffin (BEL) vs. Mardy Fish (USA) : Fish came through a tough five set mach against James Ward just two days ago and the big question here is whether his body can recover in time for this tough match-up. Mardy hasn't been able to get much match play before The Championships, with a heart ailment requiring minor surgery just last month. He's up against the Baby Faced Assassin David Goffin, who continues to impress. Goffin is trying to become the first man in the Open Era to make the Round of 16 at his first two consecutive Slam appearances.
Pick: Goffin in five sets.
Five more to watch (because it's Middle Saturday!)
Marin Cilic (CRO)  vs. Sam Querrey (USA): Can the Queen's Club champion stop Querrey's resurgent run?
Philipp Kohlschreiber (GER)  vs. Lukas Rosol (CZE): A battle between the last two men to beat Rafael Nadal. Is Rosol for real?
Roberta Vinci (ITA) vs. Mirjana Lucic (CRO): A win for Mirjana would put her into the fourth round of a Slam for the first time since her semi-final run in 1999.
Maria Kirilenko (RUS) & Nadia Petrova (RUS)  vs. Serena Williams (USA) & Venus Williams (USA): A good test for the Williamses against a very solid doubles team.
Jo-Wilfried Tsonga (FRA)  vs. Lukas Lacko (SVK): Because who doesn't like to see Jo-Willy fly around a grass court. He says he won't dive anymore because he hurt his finger, but I don't know. Something tells me he just can't help himself.
