The Mariners announced today that they have designated outfielder Daniel Robertson for assignment in order to clear a spot on the roster for right-hander Joe Wieland, whose contract has been selected from Triple-A Tacoma. Wieland will start tonight’s game for Seattle.

The 30-year-old Robertson made 21 plate appearances for the Mariners this season and batted .263/.300/316. He’s had limited experience across the past three seasons between Seattle, Anaheim and Texas, compiling a .273/.322/.325 batting line in 298 trips to the plate. The Mariners claimed Robertson off waivers from the Angels this past winter — the second time that GM Jerry Dipoto has claimed Robertson (he also did so when he was the Angels’ GM). Robertson, who is capable of playing all three outfield positions, batted .281/.341/.418 with 14 doubles, seven triples, six homers and 10 steals with Triple-A Tacoma this season.
Wieland, also acquired this offseason (from the Dodgers), started the season terribly and found himself outrighted off the 40-man roster. However, after posting a 17.31 ERA through his first 13 innings, he’s rebounded with a 3.67 ERA and an 83-to-23 K/BB ratio in 90 2/3 innings across his past 17 starts. Wieland looked like a potential rotation option for the Padres when he came up as a 22-year-old back in 2012 but underwent Tommy John surgery and missed the entire 2013 season. Since that time he’s been traded from San Diego to Los Angeles (in the Matt Kemp blockbuster) and struggled to stick in the big leagues. Now 26 years of age, Wieland has a 5.85 ERA in 47 2/3 Major League innings, though his recent work in the hitter-friendly Pacific Coast League is certainly more encouraging.
