The Detroit Tigers are roaring again. After limping into the 2006 postseason, Detroit stunned the baseball world by beating the Yankees in the ALDS and the A's in the ALCS on their way to the World Series. One of the team's stars has been Carlos Guillen, a talented veteran who joined the team in 2004. During the 2006 campaign, Guillen batted .320, hit 19 home runs and drove in 85 runs, all the while playing a solid shortstop and then, when Sean Casey went down with an injury, an equally solid first base. Carlos Guillen has hand signed this official MLB baseball, which comes complete with a Steiner Sports Certificate of Authenticity.
