47 years old (Born on December 30, 1977)
Happy Birthday, Grant! Hope your celebration is as flawless and exciting as that incredible streak of 44 consecutive saves you pulled off with the Oakland Athletics. Seriously—your arm deserves its own Hall of Fame plaque for sheer reliability!And let's not forget your well-deserved All-Star nod in 2013; clearly, even baseball's elite hitters knew better than to mess with "The Balfour Rage." May this birthday bring you joy, laughter, and fewer stressful ninth innings—but just enough excitement to remind everyone you're still unbeatable when it counts most. Cheers to another year of greatness on and off the mound!
