Insights

Peak run came in a three-year window

Janković’s deepest Grand Slam results were concentrated from 2007 to 2010: one finalist finish, two semifinals, and one quarterfinal. That stretch includes her only final in 2008, plus semifinal runs in 2007, 2008, and 2010.

Australian Open was her earliest breakthrough stage

Her first Grand Slam appearance in the data is the 2003 Australian Open at age 17, and Melbourne is also where she first reached the semifinals, in 2008 at age 22. Across the four majors, the Australian Open is the only one that shows both an early debut and a semifinal peak before age 23.

Wimbledon was the hardest major to convert into a deep run

She reached only one Wimbledon quarterfinal-equivalent or better result in the table: a 2010 fourth-round showing, with her best Wimbledon result listed as one semifinalist overall? No—her Wimbledon row set tops out at R16 in the results table, while her best-results summary shows no Wimbledon-specific deep run beyond the aggregate semifinal count.

Late-career decline was steep after age 29

From age 29 onward, her Grand Slam results never again went beyond the fourth round: R16 at the 2014 Australian Open, French Open, and US Open, then R128 or R64 in every Slam from 2015 through 2017. That contrasts sharply with the 2007-2010 peak years.

Her best season by results was 2008

In 2008 she produced her only final at the US Open, plus a semifinal at the Australian Open and another semifinal at the French Open. No other year in the table matches that combination of one final and two semifinals.
