Denis Istomin

Insights

Peak came in 2017, with his only Grand Slam round of 16

Istomin’s best Slam result was R16, and it happened once: at the 2017 Australian Open, when he was 30. That stands out against his overall profile of 35 wins in 80 matches and only three total R16 finishes.

His deepest run was followed by a sharp drop the next season

After reaching R16 in 2017, he opened 2018 with R64 at the Australian Open and then fell to R128 at the French Open, Wimbledon, and US Open. That sequence shows a clear step down from his 2017 peak.

Wimbledon was his most volatile major

At Wimbledon he reached R16 in 2012 and R32 in 2010, 2014, and 2016, but also exited in R128 in 2009, 2013, 2015, 2017, and 2019. The spread from R16 to R128 is wider there than at any other Slam in his record.

Australian Open was his strongest Slam overall

His Australian Open results include R16 in 2017, R32 in 2010 and 2014, and R64 in 2008, 2009, 2012, 2013, and 2018. By contrast, his French Open and US Open records never produced more than one R16-equivalent run each.

His career stretched from age 19 to 34, but the late years were mostly early exits

Istomin’s Slam career began at age 19 in 2006 and ended at age 34 in 2021. From 2018 through 2021, every listed result was R128 except the 2018 Australian Open R64, indicating a late-career decline in round depth.
