Zych (shoulder) was activated from the DL on Tuesday.
Before injuring his shoulder, Zych had posted a solid 3.00 ERA and 1.25 WHIP for over 12 innings. Fortunately, he returned to his form while on his rehab assignment. Zych threw four hitless rehab innings across Seattle's minor league affiliates, striking out six batters along the way. Upon Zych's activation, Stefen Romero was optioned to Triple-A Tacoma.
