The San Francisco Giants acquired Freddy Sanchez from the Pittsburgh Pirates at the 2009 trade deadline in exchange for top prospect Tim Alderson.
Alderson, a right-handed pitcher, was the No. 4 prospect in the San Francisco farm system and the No. 45 prospect in baseball at the start of 2009, according to Baseball America.
It was the second time in his career that he had been traded, as he was dealt from Boston to Pittsburgh at the 2003 trade deadline in exchange for veteran starter Jeff Suppan. This time around, he was the established centerpiece and not the prospect.
