Baker (b. 1980) was a first round (40th overall) pick by the Red Sox in the 1999 June Amateur Draft out of a Massachusetts high school. He played in the minors from 1999 to 2007 in the Red Sox, Padres, Braves and Twins organizations. He would end up making it to AAA. He had a record of 47-44 with 769 strike outs and a 3.98 ERA.
I mailed to Baker on March 19 and got the cards back on April 18, for a 30-day TAT.
