The Orioles hope to retain free agent first baseman Chris Davis. If they don't, they're hoping that Mark Trumbo will help make up for some of the lost power.
Baltimore acquired Trumbo and left-hander C.J. Riefenhauser from Seattle on Wednesday for catcher Steve Clevenger.
"The addition of a proven major league hitter like Mark Trumbo today lengthens our lineup, and it gives us another hitter in the lineup who can hit both left-handed and right-handed pitching and in Mark's case, he can hit the ball out of our ballpark," Orioles executive vice president of baseball operations Dan Duquette said.
Seattle acquired Riefenhauser from Tampa Bay to Seattle in a six-player trade. But the Mariners wanted to shed the salary of Trumbo, who made $6.9 million this year after winning in arbitration and is likely to earn about $9 million next season - his last before becoming eligible for free agency.
Trumbo hit .262 with 22 homers and 64 RBI s in 142 games this year with the Mariners and Arizona.
"It was not an ideal fit on our roster," new Seattle general manager Jerry Dipoto said. "The ability to bring in a left-handed hitting backup catcher created enough payroll relief and roster flexibility to be able to do some other things."
Baltimore will be the 29-year-old Trumbo's fourth team since 2013, when Dipoto traded him from the Los Angeles Angels to the Diamondbacks.
Trumbo averaged more than 30 home runs and 90 RBIs from 2011-13 with the Angels.
"I told Mark when we made the deal, 'Please do not take this the wrong way.' I like him quite a bit. He's a wonderful guy," Dipoto said. "I think he has a lot of skills that he brings to the table. It's difficult to trade away right-handed power."
Trumbo wasn't surprised by trade talk.
"I was aware that I was in the position that this might well happen," he said. "There were a few teams that were mentioned before, but to be honest, the Oriol es weren't one that I had heard, at all."
Baltimore has holes at all the positions Trumbo plays - first base, right field, left field and designated hitter. Duquette said he will continue to look to fill those vacancies.
"This isn't the last move the team is going to make to put our team together for 2016," he said. "I can't tell you who we're going to sign in the future."
Notes: Baltimore also announced that they have acquired catcher Francisco Pena from the Kansas City Royals in exchange for cash considerations. To make room on the 40-man roster, infielder Paul Janish has been designated for assignment. Pena, 26, batted .251 with 13 home runs and 48 RBIs in 95 games with Triple-A Omaha in 2015. In 784 career minor league games, Pena has hit .238 with 80 home runs and 352 RBIs. He has played in nine career major league games with Kansas City. Janish, 33, hit .286 with three doubles, three RBIs and four runs scored in 14 games with the Orioles in 2015. ... Baltimore also agreed Wednesday to a $2.6 million, one-year contract with right-hander Vance Worley, avoiding arbitration.
