#T4 Simone Bolelli
Like Thomaz Bellucci, Simone Bolelli has also endured defeats in all 14 matches he has contested against Federer, Nadal and Djokovic.
Bolelli is 0/4 against Federer, losing two Davis Cup matches (2009 and 2014), the 2008 Basel quarterfinal and in the second round at the 2015 Australian Open. The last one was right before Federer went on to lose to another Italian, Andreas Seppi, in the next round in Melbourne.
Against Nadal, the Italian is winless in six matches - twice at the French Open, and once each in Madrid, Doha, Basel and Rotterdam.
Bolelli hasn't managed to take a set off Djokovic in four tour-level clashes - Australian Open, Cincinnati, Halle, and in their most recent meeting at 2015 Beijing.
#3 Potito Starace
Potito Starace is winless in 15 cumulative matches against Federer, Nadal and Djokovic.
In seven meetings with Federer between 2004 and 2013, Potito Starace has never taken a set off the Swiss maestro. The two have met twice at a Masters 1000, once in the Davis Cup, and four times at the ATP 250 level.
Starace is 0/6 in clashes with Nadal spanning between 2005 and 2010 - once apiece at a Masters 1000 and the Beijing Olympics, twice in Barcelona and twice at the ATP 250 level.
Both of Starace's meetings with Djokovic have happened in the opening round at Grand Slams, with the Serb emerging unscathed without dropping a set on each occasion.
