Beltre's breakthrough season was rather well timed -- he was a free agent after '04 and signed a five-year, $64 million deal with the Seattle Mariners.
But he matched his monstrous numbers during his final season in LA with Seattle. His best season was 2007, when he batted .276 with 26 homers, 99 RBIs, and an .802 OPS.
Beltre never had an on-base percentage above .327 with Seattle, and his peak slugging percentage was .482.
