O's purchase contract of Phils outfielder Roberson
The 28-year-old hit .286 (8-for-28) in two stints with the Phillies last year and batted .266 in 113 games for Triple-A Ottawa, playing primarily in center field. A ninth-round pick in the 2001 amateur draft, Roberson made his major league debut in 2006.
To make room for Roberson on the 40-man roster, Baltimore designated outfielder Jeff Fiorentino for assignment.
Philadelphia also sent catcher Pete Laforest outright to Triple-A Lehigh Valley.
