Beckham did not make it to Triple-A until the 2011 season and stayed there until Wednesday, while fellow top five picks of the same Draft -- Pedro Alvarez , Buster Posey, Eric Hosmer and Brian Matusz -- have since made the big leagues.
"It's still a dream come true to play in the Major Leagues," Beckham said. "It would have been great if it was a two- or three-year process, but you have to play the cards you're dealt. Sometimes, it takes a guy longer than another. You can't try to measure your success against other guys."
Manager Joe Maddon said he does not envision using Beckham in "high-leverage moments," but he still feels Beckham's time spent here could be valuable.
"He may not hardly get on the field, but when you get a guy up here and he feels what it's like, that can do something for his confidence," Maddon said. "Just being here and watching this could help."
