Aybar, who turned 23 yesterday, hit .283/.327/.413 in Triple A last year (equivalent to .234/.269/.328 in the Majors). Baseball America ranks Aybar as the Angels’ third best prospect, behind Brandon Wood and Nick Adenhart. Aybar has come up in many trade rumors already in his career. According to BA, Aybar handles the bat well and his glove, arm, and speed are plus tools. They see him as more of a bottom-of-the-order, defensive-minded SS.
My feeling is that swapping out Uribe and Crede for Aybar and Fields would make the Sox significantly worse in 2007…but it is just a trade rumor right now.
