Groth’s fastest recorded serve is 263.4 km/h (163.7 mph), hit during a Challenger event in Busan, South Korea, in 2012 (The Nightly). At the time, this was the fastest serve ever recorded in professional tennis.

• The record has since been broken by other players, but remains a defining highlight of Groth’s tennis career.

What this means: for a player who never cracked the top 150 in singles, the serve record gave him a unique place in tennis history that no ranking could replace.

Quotes from Groth and the media

“The pressure on my family has made this decision necessary.”

Sam Groth, resignation statement (as reported by The Nightly (Australian news outlet))

“His resignation triggers a by-election in the marginal seat of Nepean, a seat the Liberals will need to defend.”

ABC News (Australian public broadcaster)

Sam Groth leaves behind a mixed legacy: a tennis record that still stands as one of the fastest serves ever, and a political career that ended nearly as quickly as it began. For Victoria’s Liberal Party, the departure of a former tennis star who brought media attention but struggled to convert it into lasting influence leaves a seat that may be hard to hold. The by-election will test whether the party can retain Nepean without its celebrity candidate. For Groth, the choice is clear: a return to private life, or a second act that no one yet knows.
