#3 Fernando Verdasco (Spain): 61
From: 2003 Wimbledon to 2018 Wimbledon.
Win-Loss record: 102-61.
Best Performance: Semi-Finals (2009 Australian Open)
Fernando Verdasco made his Grand slam debut at the 2003 Wimbledon, losing to Jarkko Nieminen in the first round. Verdasco is yet to miss a grand slam in his career, and has played 61 consecutive grand slam. Verdasco's first grand slam match win came at the 2003 US Open. He qualified as a lucky loser and knocked out 17th seed and fellow countryman Tommy Robredo in the first round.
Verdasco's best result at a slam came at the 2009 Australian Open. He reached the semi-finals and lost to eventual champion Rafael Nadal. The match lasted over 5 hours and is ranked as one of the greatest of the Open era. Verdasco would have his revenge years later, knocking out Nadal in the first round of the 2016 Australian Open. Verdasco reached the quarter-finals of the US Open twice (2009, 2010) and Wimbledon once (2013). He has reached the 4th round at the French Open 7 times, but has failed to progress beyond.
Verdasco had the potential to win multiple slams, but failed to live up to it. This is not to suggest that he has not had his moments. He is a former World No.7, and finished in the top 10 for 2 straight years (2009, 2010). He has also won the Davis Cup on 3 separate occasions and won the Hopman cup in 2013. Verdasco is capable of beating anyone on his day, and remains the biggest giant slayer in modern day tennis. He won his 100th grand slam match at the 2018 French Open and looks set to win many more.
Verdasco is only 34 and is likely to end at the top of this list. The men's field has never been more open than now so don't be surprised if Verdasco feasts on it one day. Among other things, if the Spaniard manages to retire without missing a single Grand slam, it would be one of the greatest achievements in tennis history.
