Both are slated to join the A's in Major League camp next year as non-roster invitees.
The 32-year-old Eyre, brother of Major League hurler Scott Eyre, was 5-4 with a 3.50 ERA and two saves in 49 relief appearances for Triple-A Oklahoma City, where he spent all of 2010 in the Texas organization. He was last seen on a Major League mound in 2009, when he compiled a 4.50 ERA in 17 relief appearances for Texas. Eyre also pitched for the Twins -- gathering 92 appearances -- in three seasons prior.
Blackley, meanwhile, enjoyed a successful second half with the A's organization this year following a slow start -- 8.53 ERA in four appearances -- with the Mets' Triple-A club. The Mets released him on May 1, but he was signed by the A's 13 days later and proceeded to go 2-1 with a 2.52 ERA in 15 games, including four starts, with Triple-A Sacramento following two starts at Class A Stockton.
Blackley, 28, is currently 4-1 with a 2.16 ERA in five starts for Hermosillo in the Mexican Winter League. He initially made his Major League debut with Seattle in 2004 and also has big league experience with San Francisco. Overall, the Australian native is 1-3 with a 9.35 ERA in eight career appearances -- all starts -- in the Majors.
A member of the A's brass said Friday that Blackley will continue to see work as both a starter and reliever while with the organization.
