Yankees acquire Tateyama, sign Zagurski
Both men are expected to be assigned to Triple-A Scranton/Wilkes-Barre, and the RailRiders will have to make a pair of corresponding moves before activating them.
Zagurski, 30, was designated for assignment by Pittsburgh on June 15, and elected free agency after clearing waivers four days later. He split this season between the Pirates and the Triple-A Indianapolis Indians, allowing 10 earned runs in six innings over six appearances in the Majors but posting a 2.14 ERA and 37 strikeouts over 21 innings in 19 Minor League appearances.
His contract also includes an opt-out clause, which will allow Zagurski to become a free agent on August 15 if he has not been promoted to the Majors.
Tateyama, a 37-year-old side-arming righty, spent all of 2013 at Triple-A Round Rock after being released by Texas and re-signed to a Minor League deal over the winter; at Triple-A, he had a 4.24 ERA with 44 strikeouts in 34 innings pitched over 23 appearances.
Like ex-Yankee Cody Eppley, Tateyama is a bit of a "righty specialist," and he held righty batters to a .200 average in 53 Major League appearances for the Rangers in 2011 and 2012.
