The Mariners announced Monday that they’ve claimed righty Robert Dugger off waivers from the Marlins. Seattle also lost righty Ian Hamilton to the Phillies and righty Walker Lockett to the Blue Jays.
Dugger, 25, was an 18th-round pick of the Mariners back in 2016 but landed in Miami as part of the package that sent Dee Strange-Gordon to Seattle. He’s made a handful of appearances with the Fish over the past two seasons but hasn’t found much success, posting a 7.40 ERA and a 29-to-20 K/BB ratio in 45 innings. Dugger’s struggles have persisted in Triple-A, although he had a solid track record up through the Double-A level, where he owns a 3.60 ERA with 9.0 K/9 against 2.9 BB/9 in 180 innings of work.
Lack of track record in the Majors and Triple-A not withstanding, Dugger gives the Mariners an optionable piece of rotation depth — perhaps one they feel will benefit from a change of scenery. Dugger also saw a pronounced jump in his four-seam fastball velocity from 2019 to 2020 (90.3 mph to 92.1 mph) and in his heater’s spin rate (2191 rpm to 2321 rpm), so perhaps the Mariners believe they can help him build upon those positive indicators.
