Happy Birthday, John Jaso! To the catcher with an eagle eye who made pitchers sweat since your MLB debut in 2008 for the Tampa Bay Rays—your patience at bat was legendary. Rumor has it umpires secretly admired you because they knew you'd never swing at a bad pitch!When you joined Seattle Mariners in 2012, fans quickly learned that watching your plate discipline was as entertaining as any home run derby. May this birthday bring fewer curveballs and more fastballs down the middle of life's strike zone.
Here's to another year filled with laughter, success—and plenty of walks!
