Athletics sent RHP Chris Resop outright to Triple-A Sacramento.

Resop was designated for assignment by Oakland last week and passed through waivers. The right-hander had a 6.00 ERA and 13/10 K/BB ratio in 18 innings with the A's.

Athletics agreed to terms with RHP Chris Resop to a one-year, $1.35 million contract.

Athletics acquired RHP Chris Resop from the Pirates in exchange for RHP Zach Thornton.

Resop, a dependable middle reliever, posted a 3.91 ERA and 46/24 K/BB ratio over 73 2/3 innings with the Pirates in 2012. He'll be a welcomed addition to an already strong A's bullpen.

Pirates and RHP Chris Resop avoided arbitration by agreeing to a one-year, $850,000 contract.

Resop was arbitration-eligible for the first time this winter. The 29-year-old right-hander posted a 4.82 ERA and 79/30 K/BB ratio over 69 2/3 innings last season. He'll set-up for closer Joel Hanrahan again in 2012.
