In October 1995, Christian Ruud became the highest-ranked Norwegian tennis player ever. He was No. 39 in the world, reached the round of 16 at the 1997 Australian Open and represented his country at the Olympics three times.

It took about 26 years, but in February 2020 Ruud’s ranking was eclipsed — by his son, Casper, 22, who has obliterated his father’s accomplishments, winning four ATP clay-court tournaments this year, and reached a career-high No. 10 ranking.
