The Ballplayers
A Baseball Player Encyclopedia (Olivo to Ozuna)

Baseball Almanac is pleased to present a comprehensive list of EVERY Major League player whose last name falls between the names above. Included on the chart are links to the players biography, the years he played, an Auto(graphed) baseball card notation (Y=Yes) and a (HOF) Hall of Fame mark (Y=Yes). Bold entries stand for active players which are defined as those who played in at least one Major League game during the most recently completed season.

"I went three days without a hit and my wife refused to cook me dinner. When I didn't get a hit the fourth day, she gave her tickets away. I guess if I ever go a week without a hit, I'll be sleeping in a tent in the backyard." - Al Oliver
