SEATTLE — The Seattle Mariners signed outfielder Rob Refsnyder to a one-year contract Monday, adding an experienced righthanded hitter to their roster.

Refsnyder, who turns 35 in March, spent the past four seasons with the Red Sox. He batted .269 with nine home runs, 30 RBIs, and an .838 OPS in 70 games and 209 plate appearances this year.

With the Mariners, he figures to get playing time at designated hitter against lefthanded pitching. He could also provide an option in the corner outfield spots and perhaps spell Josh Naylor at first base.

“Rob has been one of the most productive hitters against lefthanded pitching over the last four seasons and provides balance and impact offensively to our lineup,” Mariners general manager Justin Hollander said in a news release announcing the deal.

Refsnyder has batted over .300 against lefthanders for five straight seasons. He is a .255 career hitter overall with 33 homers and a .730 OPS in 10 major league seasons with the Yankees, Blue Jays, Rays, Rangers, Twins, and Red Sox.

Refsnyder, born in South Korea, was the Most Outstanding Player at the 2012 College World Series as he helped Arizona win the NCAA championship.
