The Mariners added to their defense and up-tempo offense with a second trade Friday, dealing RHP Nathan Karns, who finished the season on the disabled list, for Jarrod Dyson, 32, who was the Royals fourth outfielder and ace pinch-runner.
“Jarrod brings us a winning pedigree, along with elite-level defense and base running,” Dipoto said. “He joins players like Leonys Martin and Jean Segura in creating a disruptive element on the bases to our offensive game, while also enhancing our ability to prevent runs on defense.”
Dyson. 5-10 and 160 pounds, had a career-high 299 at-bats last season in Kansas City, where he stole 30 bases in 37 attempts while hitting .278 with a 3.1 WAR. Dyson has stolen at least 30 bases in four of the past five seasons. From Sept. 2-17, he hit in 10 consecutive games, batting .372.
Dyson had 50 starts in center field, 21 in right and 12 in left. He is a replacement for Seth Smith, the fourth outfielder in Seattle last season who was traded Friday to Baltimore for starting RHP Yovani Gallardo.
Since 2012, Dyson has 156 stolen bases, tied for sixth-most in the majors. In that span the left-handed hitter has been successful on 84.8 percent of his stolen base attempts, second in the majors.
A native of McComb, MS., Dyson was selected by Kansas City in the 50th round of the 2006 MLB draft out of Southwest Mississippi JC. In parts of seven seasons with the Royals, he is a career .260 hitter with 48 doubles, 29 triples, 7 home runs, 101 RBI and 176 stolen bases in 550 games.
Karns was 6-2 with a 5.15 ERA in 22 games, including 15 starts, with Seattle last season. The 6-foot-3, 225-pound right-hander went on the disabled list July 30 with a low back strain and did not return.
He was acquired by Seattle along with LHP C.J. Riefenhauser and OF Boog Powell from Tampa Bay in exchange for RHP Danny Farquhar, INF Brad Miller and INF Logan Morrison Nov. 5, 2015. In parts of four MLB seasons, he has a record of 14-9 with 4.41 ERA with 270 strikeouts and 111 walks in 54 career games, including 46 starts.
