Mariners Select Shawn Armstrong

By Steve Adams | August 28, 2018 at 4:29pm CDT

The Mariners announced Tuesday that they’ve selected the contract of right-hander Shawn Armstrong from Triple-A Tacoma and optioned fellow right-hander Nick Rumbelow to Double-A Arkansas to open a spot on the active roster. Seattle already had an open spot on the 40-man roster, so no further moves were necessary to accommodate Armstrong’s return to the big leagues.

Armstrong, 27, saw time in the Majors with the Indians across the 2015-17 seasons but was traded to Seattle in exchange for international bonus pool space this past offseason. The Mariners exposed Armstrong to outright waivers just three months later when a need for roster space arose in Spring Training. He’d go on to clear and remain in the organization, which could prove fortuitous for the Mariners.

Through 56 innings out of the Rainiers’ bullpen in Triple-A, Armstrong has been nothing short of overpowering. He’s posted a sterling 1.77 ERA while averaging 13.2 strikeouts, 4.2 walks and 0.48 homers per nine innings pitched, collecting 15 saves along the way. It should be noted that Armstrong is no stranger to gaudy Triple-A numbers, but he’s done a better job of limiting walks this year than in recent seasons while still maintaining a hefty strikeout rate.

Armstrong will join the Mariners with 43 1/3 innings of Major League experience already under his belt from his time with the Cleveland organization. In that time, he’s pitched to a 3.53 ERA but hasn’t matched his minor league strikeout tendencies, averaging 7.9 K/9 against 3.5 BB/9 with a 41.6 percent ground-ball rate.

    I like that one, but I am waiting for the one that says the Mariners acquire Gio Gonzalez or Marco Estrada

      Or not Marco Estrada because he’s been awful

    Confused as to why we have waited this long to bring him up?

      Probably because he’s out of options and would never clear waivers. They may have been overvaluing the flexibility of some of their other relievers.
