Let's make this birthday one to remember.

38 years old (Born on October 07, 1987)

Happy Birthday, Sam Querrey! May your celebrations be as powerful and unstoppable as that legendary serve of yours. You've aced another year with style—just like when you climbed to number 17 in the world rankings back in January 2011.

From thrilling fans at Flushing Meadows by reaching the fourth round twice (2008 & 2010), you've consistently shown us how it's done on court. Here's hoping this birthday brings more joy than a perfectly executed overhead smash—and fewer double faults off-court!

Keep serving up greatness, Sam; age is just a number—but hey, you're pretty good with numbers anyway!
