Austria's Andreas Haider-Maurer heads the field for a fairly weak challenger on the clay courts of San Benedetto.
The entry list reflects that this is one of the weakest challengers being held this week. The presence of the Olympics later this month has squashed the calendar so much that there are six events (ATP and challengers) being held in Europe this week.
Ranked 159 in the world, Haider-Maurer would not normally expect to be top seed in a challenger but he finds himself with a fantastic opportunity to move back into the world's top 150. The tall Austrian has shown some decent form over the past couple of months, qualifying for the French Open and making the final of an event in Marburg.
Look out for Canada's Peter Polansky this week, the in-form player in the draw. Polansky made the final of a challenger in Panama City at the weekend before hopping on a quick transatlantic flight. Providing he can survive the first couple of rounds, he should be a threat this week.
There are numerous former junior stars in this draw. Belarus' Uladzimir Ignatik was highly rated a couple of years ago but appears to have become stuck at this level and fifth seed Gianluco Naso was a junior rival of Andy Murray back in 2005 but while the latter has just been competing in his fourth Grand Slam final, Naso has never made the top 100.
