He is an alumnus of Dowling Catholic High School in West Des Moines, Iowa and the University of Arkansas.
Drafted by the Cincinnati Reds in the 34th round of the 1989 Major League Baseball Draft, Pose would make his Major League Baseball debut with the Florida Marlins on April 5, 1993, and appear in his final game on September 29, 2000.
Nevertheless, he only appeared in 15 games with the expansion Marlins, as the bulk of his career playing time came later in the decade with the New York Yankees and Kansas City Royals.
Despite earning the praise of Royals Manager Tony Muser, Pose's playing time decreased in 2000, as he would start in only three games, appearing almost exclusively as a pinch hitter.
Pose portrayed the fictional baseball player "Matt Crane" in the 1999 film For Love of the Game starring Kevin Costner.
