The Orioles have taken South Korean right-hander Suk-min Yoon off the organization's 40-man roster and outrighted him to Triple-A Norfolk.
Yoon and infielder Cord Phelps, who was designated for assignment Sunday in order to make room for right-hander Miguel Gonzalez, were removed from the 40-man roster, cleared waivers and outrighted to Norfolk on Saturday.
Phelps had been outrighted previously, and had the option of refusing a minor league assignment and becoming a free agent, but decided to remain in the organization.
Yoon was signed to a three-year, $5.575 million contract in February. Despite pitching the entire season at Norfolk, he is making a $750,000 base salary this season — he also received a $675,000 signing bonus — and is slated to make $1.75 million in 2015 and $2.4 million in 2016.
Yoon, 28, is 3-8 with a 5.56 ERA in 22 games (17 starts) in his first professional season in the United States, after pitching his entire pro career in South Korea.
The moves are intended to clear space for players not currently on the 40-man roster, whether they are minor league players or players acquired from outside the organization.
With the moves, the Orioles currently have two spots available on the 40-man roster. They can create another spot by transferring third baseman Manny Machado to the 60-day disabled list.
