The Orioles and the Seattle Mariners have not made official the trade that will send first baseman Mark Trumbo to Baltimore for Steve Clevenger, but the third piece of the deal has now been identified.
According to an industry source, the Orioles will also receive left-hander C.J. Riefenhauser, a 25-year-old who had previously spent his career with the Tampa Bay Rays before a November trade to Seattle.
In turn, the Orioles will pick up Trumbo's full salary, which likely will be about $9 million or so. Trumbo is in his final year of arbitration.
Riefenhauser is 1-0 with a 6.30 ERA in 24 big league games with the Rays over parts of two seasons. A former 20th-round pick of Tampa Bay, he has posted a 2.77 ERA in six seasons in the minors.
Assuming the trade goes through -- the sides were waiting on a medical review -- Riefenhauser will be placed on the 40-man roster. He does have one minor league option remaining, which is attractive to an Orioles team that likes to shuffle bullpen pieces between the minors and majors.
