The Mariners signed Corey Patterson to a minor league deal and invited him to Spring Training, according to Geoff Baker of the Seattle Times. The 30-year-old struggled through 16 games with the Nationals and Brewers last year, putting up a .207 OPS in 30 plate appearances.
The Cubs chose Patterson third overall in the 1998 draft, but he disappointed in the major leagues. He hit 24 homers, stole 32 bases and posted a .771 OPS five years ago, but hasn't matched that production since. FanGraphs likes his defense, however, so the Mariners do add depth to help patrol spacious Safeco Field.
