A former second-round pick with the Expos in the 2003 First-Year Player Draft, Owens, 28, spent three-plus seasons with the White Sox before joining the Mariners' organization this past season.
His best year in the Major Leagues was in 2007, when he hit .267 with one home run, 17 RBIs and 32 stolen bases in 93 games with the White Sox. In seven Minor League seasons, Owens has a .296 lifetime batting average, with 396 runs scored and a .364 on-base percentage.
When Jim Bowden was Washington's general manager, one of his first trades was sending Owens to Chicago for outfielder Alex Escobar on Feb. 13, 2005.
