Pozo was signed as an undrafted amateur
free agent by the
Seattle Mariners in August 1990. He spent three years in the Mariners' minor league system, advancing from the
Class A Short-Season Bellingham Mariners to the
Triple-A Tacoma Rainiers. He was the Mariners' minor league player of the year in 1993, leading the all minor leaguers with 44 doubles and was named the
California League Player of the Month in July in August while playing for the
Riverside Pilots.
Baseball America ranked him as the #60 prospect in baseball following that season. Pozo made his major league debut on September 12, 1995, with Seattle, hitting a pop out in one
at bat; it was his only MLB appearance with the Mariners. After starting the 1996 season with Tacoma, Pozo was traded to the
Boston Red Sox for
Jeff Manto in July. Pozo spent the next two seasons splitting time between Boston and the Triple-A
Pawtucket Red Sox. In his third game with the Red Sox, on July 28, 1996, he hit a
grand slam off of
Minnesota Twins relief pitcher Eddie Guardado. In 26 MLB games, Pozo batted 14-for-74 (.189) with one
home run and 14
RBIs. ==References==
