After seven seasons as a backup catcher for the Boston Red Sox (1995-2001), a then 32-year-old Hatteberg underwent elbow surgery. Afterwards, he was rendered unable to throw a baseball. Despite this, Beane signed him in 2002 to a one-year contract for $950,000 plus incentives, and moved him first base/designated hitter to replace their star Jason Giambi, who had just signed a massive contract with the New York Yankees. An entire chapter of Lewis’ book is devoted to Hatteberg, who was given the starting first base position ahead of star prospect Carlos Peña. Beane believed in Hatteberg’s high on base percentage and lack of strikeouts, and Hatteberg eventually emerged as a skilled first basemen. In 2004, he hit .284 with 15 home runs, 82 RBIs, and an impressive 72 walks. He was signed in 2006 to the Cincinnati Reds, where he continued to play well, and retired after the 2008 season.
