The Rockies have signed Sean White to a minor league contract with an invitation to Spring Training, tweets Troy Renck of The Denver Post. He was outrighted by the Mariners earlier this offseason and became a free agent soon thereafter.
The 29-year-old right-handed reliever posted a 5.24 ERA with just 3.9 K/9 in 34 1/3 innings for Seattle in 2010. White made up for the low strikeout rate with an equally low walk rate (2.9 BB/9) and a decent ground ball rate (44.6%). His big league career consists of 134 innings, all with the Mariners, and a 4.16 ERA with 4.0 K/9, 3.4 BB/9, and 48.4% ground balls.
The Rockies can control White for at least three more years as an arbitration-eligible player if they choose.
