The Baltimore Orioles have exercised a $1 million option on right-handed reliever Luis Ayala and declined an $11 million option on first baseman Mark Reynolds .
Reynolds gets a $500,000 buyout as part of the contract he signed with Arizona in 2010 and is eligible for salary arbitration. He hit .221 with 23 homers and 69 RBI in 135 games.
The 34-year-old Ayala went 5-5 with a 2.64 ERA in 66 appearances with Baltimore. He allowed one earned run or fewer in all but seven outings.
The Orioles also selected the contract of pitcher Zach Clark from Triple-A Norfolk, adding him to the 40-man roster. Clark was a combined 15-7 with a 2.79 ERA with Norfolk and Double-A Bowie.
