The Mariners and right-hander Christian Bergman have agreed to a minor league pact, per SB Nation’s Chris Cotillo (via Twitter). The All Bases Covered Sports Management client will be returning to the Seattle organization for a second season and will head to Major League Spring Training. Bergman, 30 in May, appeared in 13 games for Seattle last season — eight starts and five relief appearances — working to a total of 54 innings. In that time, the former Rockies hurler posted an even 5.00 ERA with 5.5 K/9, 2.5 BB/9, 2.0 HR/9 and a 37.7 percent ground-ball rate. Though he’s never experienced much in the way of prolonged success in the Majors (5.58 ERA in 201 2/3 frames between the Rockies and Mariners), Bergman has demonstrated solid K/BB numbers in the minors. In 235 innings at the Triple-A level, Bergman owns a 4.40 ERA with 6.2 K/9 against 1.9 BB/9.
