Let's make this birthday one to remember.

38 years old (Born on September 07, 1986)

Happy Birthday, Denis Istomin! You're the tennis ace who served up unforgettable moments—like clinching that thrilling doubles title at the 2013 Kremlin Cup. Your powerful shots and relentless spirit made you a fan favorite on courts worldwide.

And let's not forget your impressive runs as singles runner-up in both the 2012 SAP Open and the memorable battle of endurance during the 2010 New Haven Open at Yale. You've shown us all how to swing with style—and occasionally humor!

Here's wishing you another year filled with aces, smiles, victories (and fewer double faults). Keep smashing it out there!
