The Orioles acquired Hoppe and right-handers Harrison Kreiling and Brock Moore from the Mariners on Monday in exchange for outfielder Taylor Ward, Jake Rill of MLB.com reports.
Hoppe is the only big-league-ready arm the Orioles will receive in the deal, as Kreiling and Moore haven't pitched above the Single-A and Double-A levels, respectively. A 27-year-old righty, Hoppe reached the majors for the first time in April and compiled a 5.79 ERA, 1.36 WHIP and 34:11 K:BB in 28 innings while working mostly in middle relief for Seattle. He'll likely slot into a similar role in the Baltimore bullpen.
