Horacio Zeballos Jr.

Insights

Only one Grand Slam run reached the second week

Zeballos Jr.’s best result was a single R16 at the 2017 French Open, and every other Slam appearance ended by the round of 64 or earlier. That makes his 23-tournament Grand Slam career unusually concentrated at the early stages.

Clay was clearly his strongest surface in the results

His only R16 came at Roland Garros, and he also reached the round of 64 there in 2010, 2012, 2013, and 2018. Across the other majors, his best showing was only R64, with no comparable deep run.

His peak came late, at age 32

The career-best 2017 French Open result came when he was 32, and his next-best Slam finishes at age 33 were R64 at both the 2018 French Open and Wimbledon. Earlier in the record, his results were mostly R128.

He was most active in a four-year stretch, then faded to sporadic appearances

From 2010 through 2013 he played 13 of his 23 Slam tournaments, including all four majors in 2013. After that, he appeared only six more times from 2014 to 2018, with just one Slam in 2015.

His overall Slam record stayed below break-even despite 33 matches

He finished 10-23, a 30% win rate, across 33 total matches. That volume is enough to show a long career, but the results cluster heavily around first- and second-round exits.
