Juan Antonio Marín

Insights

Every Grand Slam appearance ended in the first round

Marín’s Grand Slam record is 17 matches, 17 tournaments, and 17 R128 finishes. That produces a 0-17 win-loss record, so he never advanced beyond his opening match in any Slam appearance.

He played all four majors in four straight seasons, then returned once more in 2006

From 1998 through 2000, he entered all four Grand Slams each year, giving him 12 appearances across those three seasons. After a single 2001 French Open entry, he reappeared only in 2006, with Australian Open and French Open starts.

His best Slam age window was 23-25, when he made 10 of his 17 appearances

The results table shows four Slams at age 23 in 1998, four at 24 in 1999, and four at 25 in 2000, plus one at 26 in 2001. That middle stretch accounts for the bulk of his Grand Slam activity.

His nationality changed mid-career, but every Slam result stayed the same

He is listed as Spain from 1997-1998 and Costa Rica from 1998 onward. The results table reflects that shift: his 1997 and 1998 Australian Open/US Open entries are split between Spain and Costa Rica, yet every one still ended at R128.

His 2006 return came at the oldest ages in the dataset

After a five-year gap from 2001 to 2006, he returned at ages 30 and 31. Those two 2006 appearances are the oldest in his Grand Slam record, and both again ended in the first round.
