John Isner has one of the most powerful serves in the game of tennis.  Part of the reason is that he is 6 ft 10 inches and is one of the tallest players on the tour.  Until 14, Isner played basketball before switching to tennis in a serious way.

Isner played college tennis at the University of Georgia (2004-07).  He reached the NCAA singles final and won doubles & team titles in 2007. He only started playing on ATP tour after college.

His best grand slam success came at the 2018 Wimbledon Championships, where he reached the semifinals. He achieved a peak singles ranking of world number 8 in 2018. His sponsors are Fila, Prince, Tamko, Defy, Bass Pro, Ebix, Nulo, and Runa. He has earned over $25 million.

John Isner’s Sponsors

TAMKO Building Products is one of the America’s largest manufacturers of residential and commercial roofing products.  John Isner’s father was a building contractor in North Carolina and was a frequent customer of Tamko.  In addition, Tamko’s CEO David Humphreys is an avid supporter of tennis. Supporting Isner, who has been a top American tennis player for more than a decade comes as no surprise.

Ebix

Ebix provides on-demand software and e-commerce services to the insurance, financial and healthcare industries.  Isner wears the Ebix patch on his left shoulder. Fila allows its players to wear additional patches.  Nike is strict in that regard, though it has made exception in recent years.

Runa

Inser doesn’t just endorse Runa. He is also an investor in the company.  The company  makes the popular organic guayusa tea.

Diego Schwartzman is only 5 ft 7 inches tall and is the shortest player in the ATP top 100. But the Argentine has been able to climb up the ranking with a crafty play that lets him keep up with players that are a foot taller than him. Schwartzman’s strength is his impressive return game.

Schwartzman was baptized in honor of the famous Argentine soccer player Diego Maradona. He grew up idolizing countrymen, Juan Monaco and Maximo Gonzalez.  He is also a big fan of Rafael Nadal. That’s not a surprise, considering that his favorite surface is clay. 

At the 2020 French Open, he reached the semifinals, becoming the shortest player to achieve that feat since 1980. He has reached the quarterfinals at grand slams multiple times.

His sponsors are Fila, Head, Voltaren, Peugeot, Disney+, Caviahue Creams, and High Impact Athletes. He has earned over $15 million in his career.
