Marco Chiudinelli

He then fell to 25th seed Richard Gasquet in four sets, though the points accumulated from this event ensured he broke back into the top 200.

Marco Chiudinelli (born 10 September 1981) is a retired tennis player from Switzerland.

In 1993 he finished as runner-up to Federer at the Swiss 12-and-under indoor championship in Lucerne.

As a teenager he moved to Biel to further his tennis education, joining Federer and the older Yves Allegro, who were then staying in an apartment together, and the trio spent many hours playing video games when not practicing tennis.

Marco Chiudinelli played his first professional matches in 2000, but did not compete on a regular basis until 2002.

That year he won his first tournament on the third-tier Futures circuit in Dubai, defeating a 16-year-old Jimmy Wang in the final.

He finished as runner-up to Grégory Carraz at a Futures event in Poitiers in March and secured a second Futures title at Syros in April.

Over the following months he tried unsuccessfully to qualify for the main draw of the Gerry Weber Open in Halle, the Mercedes-Benz Cup in Los Angeles, and the Canada Masters in Toronto.

In 2001, at the suggestion of Allegro, Chiudinelli moved to Halle in Germany to train.

He also attempted to qualify for the 2002 US Open, winning against a fading Cédric Pioline in the first round – this was technically a win by retirement, as Pioline stormed off court while 0-5 down in the third set.

He lost in the next round of qualifying to Argentine Gastón Etlis.

He spent the bulk of the 2003 season playing on the Challenger Tour and reached the semi-final stage of events in Fergana and, after coming through qualifying, Nottingham, where he lost to second seed John van Lottum.

Chiudinelli began 2004 well, winning 18 of his first 22 matches.

He won another Futures title in January in Doha and the following month reached his first Challenger final in Belgrade – along the way defeating a teenage Novak Djokovic in one of his earliest professional appearances.

He won his first main draw match on the ATP Tour at the 2004 Gerry Weber Open, overcoming compatriot Michel Kratochvil in straight sets, but lost in the next round to Jiří Novák.

In September he took his first Challenger title in Donetsk and came through qualifying at the 2004 AIG Japan Open in Tokyo in October, eventually reaching the round of 16 after upset victories over the higher ranked Alexander Peya and Dennis van Scheppingen.

At the 2004 Swiss Indoors, his hometown tournament, Chiudinelli defeated Albert Montañés in the first round, and lost his next match to Rainer Schüttler.

He finished the season ranked 142 in the world and having earned $97,936 in prize money, which was more than twice as high as the previous two seasons combined.

Chiudinelli's ranking reached a then high of 129 in January 2005 after making the round of 16 at the Qatar Open.

He soon received his first call up to the Switzerland Davis Cup team for the tie versus the Netherlands, losing in five sets to the more established Sjeng Schalken, and later winning the dead rubber against Peter Wessels.

After retiring through injury in his second round match against Michael Ryderstedt at Wimbledon Qualifying in June, Chiudinelli was later forced to get surgery to heal persistent pain in his shoulder.

As a consequence he did not play for the remainder of the season and his ranking fell to 287.

Chiudinelli initially struggled to recover his ranking during the first half of 2006 and had fallen to 775 in the world by the start of May.

That same month he won 10 straight matches to take successive Futures titles in Kuwait.

After coming through qualifying at the Gerry Weber Open, Chiudinelli defeated Christophe Rochus in the main draw, before falling to the seeded Kristof Vliegen in the second round – the ranking points from this event moving him back up to 359.

In July Chiudinelli enjoyed some success in doubles with partner Jean-Claude Scherrer, the pair finishing as runners-up at the Suisse Open in Gstaad.

At the 2006 US Open as a qualifier, he defeated Fernando Vicente and Feliciano López in his first two matches.

Following the US Open, Chiudinelli won the dead rubber against Serbia's Janko Tipsarević at the 2006 Davis Cup World Group play-offs and made the semi-final of the Mons Challenger in October.

He experienced a disappointing first round defeat to 5th seed David Ferrer at the 2006 Swiss Indoors, having taken the first set in a tiebreak.

He ended the season at 155 in the world, with earnings of $114,646 in singles.

He played less during the 2007 and 2008 tennis seasons, owing to persistent injury problems.

Chuidinelli entered the 2009 PTT Thailand Open, again as qualifier, and defeated German qualifier Florian Mayer in the first round and followed that up with a second-round win over former world No. 1 Marat Safin.

He lost in a three-set match to top seed Jo-Wilfried Tsonga in the quarterfinals.

He reached the semifinals in Basel, his hometown tournament by beating eighth seed Philipp Kohlschreiber, and his countryman, qualifier Michael Lammer.

He also defeated Richard Gasquet before losing to compatriot and world No. 1 Roger Federer in the semifinals.

Chiudinelli qualified for the main draw of the 2010 Australian Open and reached the second round, taking a set off world No. 3, Novak Djokovic.

A member of Switzerland's winning 2014 Davis Cup squad, he reached his highest singles ranking of 52 in February 2010 during a career that was often hindered by injury.

Marco grew up in Münchenstein and learned to play tennis at Basel Lawn Tennis Club.

He later joined a region-wide tennis group, where he first met Roger Federer, who belonged to the nearby Old Boys Tennis Club.

They quickly became friends but were soon the 'black sheep' of the group, with one or the other often forced to sit on the sidelines for disciplinary reasons.
