Rocco Dan Baldelli (/ˈrɒkoʊ bɔːlˈdɛli/; born September 25, 1981) is a former Major League Baseball outfielder and designated hitter. Because of his excellent size and speed, and in reference to his hometown, he was nicknamed "The Woonsocket Rocket" early in his professional career. After a promising beginning to his baseball career with the Tampa Bay Devil Rays, a mysterious metabolic/muscular disorder would lead to numerous injuries and force Baldelli to retire as a player at age 29. He currently works in the Tampa Bay Rays' front office.
