Martin Klizan squares off against Germany's Andreas Beck in a crucial Green Group match at the ATP Challenger Tour Finals.
Former French Open junior champion Klizan has enjoyed the best season of his career and he's currently ranked 90 in the world. The Slovak is seeded third this week but he'll need to show that he can produce his best tennis away from the European clay where he's made his name in 2011, reaching three challenger finals and a host of semis.
With a decent serve and an aggressive game he's got the tools to do well on faster surfaces but it'll be interesting to see how he fares against the experienced Beck.
The German was ranked 33 in the world two years ago but he plummeted down the rankings in 2010 before enjoying a mini-resurgence this season. He's had decent results on all surfaces and has been finishing the year strongly indoors, reaching semis in Orleans and Eckental.
It will be interesting to see how quickly Beck has managed to acclimatise as he was competing indoors in Loughborough only a few days ago.
If Bellucci finds his best form this week, this match could well be the decider for who finishes top of the group. Look for Beck to pull through in three.
