Andy Murray is about to sign a new clothing contract, while Stanislas Wawrinka has just renewed his equipment and apparel deal. The two Top 10 players are earning significantly more in endorsements than before.

Murray's five-year, $37 million contract with adidas is up for renewal this year, with the *Daily Record* reporting that Nike is also interested in the 27-year-old. As Murray is now a two-time Grand Slam champion, a new deal could be worth double the previous amount, according to the publication.

Wawrinka has signed a $20 million deal with Yonex for four years, reports *SportsBusiness Journal*. It was described as a the "most lucrative" endorsement the company has ever signed, covering racquet, clothing, and shoes.
