Coming into Day 5 of the 2012 ATP World Tour Finals, the organizers have to be thrilled with what has transpired in London thus far.
With a field loaded with the top stars in tennis, we've seen epic clashes between players like Novak Djokovic and Andy Murray, and the doubles side of things has been captivating due to upsets.
Unfortunately for some players, the round-robin format is drawing to a close for two groups on Friday. That means each match carries a massive amount of weight, as very few semifinalists are set in stone. And even the ones that are guaranteed to continue their journey have to be worried about seeding so they draw the best possible opponent in the next round.
Half of the bracket will be solved on Friday. With that in mind, here is a preview for all of Day 5's slate of matches.

(1) Novak Djokovic vs. (5) Tomas Berdych - Not Before 7:45 a.m. ET
Staying alive past Friday will prove to be a daunting task for Tomas Berdych, who will have to face off against what seems to be a top-of-his-game Novak Djokovic.
The world's No. 1-ranked player somehow survived Andy Murray's best game on in his last match, winning in a three-set thriller. Following a disappointing season, Djokovic finally seems to be putting things back together and is considered the favorite by most.
Berdych, meanwhile, got soundly defeated by the home-crowd favorite Murray before defeating Jo-Wilfried Tsonga on Wednesday. To defeat Djokovic, Berdych will have to put together a career-best match, and even that may not be enough.
Nonetheless, anytime Djoker takes the court, it's must-watch television for tennis fans.
(3) Andy Murray vs. (7) Jo-Wilfried Tsonga - Not Before 1:45 p.m. ET
Though he's a massive long-shot and will need a ton of help, one cannot help but be intrigued by what happens if Tsonga pulls off the upset.
Tsonga is a fiery competitor who is among the world's best when he's on and seems like a lethargic waste of talent when he's off. In other words, the 27-year-old Frenchman is a wild card in nearly every tournament he enters.
That is certainly the case Friday, where a win from Tsonga would end the tennis world's hopes of an Andy Murray-Roger Federer semifinal clash. However, after what we saw from both Murray and Tsonga in their last matches, that seems extremely unlikely at this point.
(2) Max Mirnyi and Daniel Nestor vs. (5) Mahesh Bhupathi and Rohan Bopanna - 6 a.m. ET
The defending tournament champions have their backs pressed firmly up against the wall after a shocking upset loss against Jonathan Marray and Frederik Nielsen on Wednesday.
Nestor and Mirnyi made plenty of unforced errors but looked to be slowly recapturing the match, but Marray and Nielsen roared back and won the last set 12-10 before an enthralled crowd.
Bhupathi and Bopanna, on the other hand, kept themselves alive on Wednesday. With both duos coming into this match with 1-1 records, Friday will send one team home, so expect a scintillating contest.
(4) Robert Lindstedt and Horia Tecau vs. (8) Jonathan Marray and Frederik Nielsen - 12 p.m. ET
In Friday's other doubles contest, well, let's just say I wouldn't bank on this being the match of the day. Lindstedt and Tecau are already eliminated with an 0-2 record, while Marray and Nielsen are guaranteed a spot in the semis.
Obviously, the match has seeding implications, so look for Marray and Nielsen to stay undefeated and capture the Group B title.
