After being drafted in the 12th Round of the 1997 Draft, Joel Pineiro would reach the majors in 2000, and made it to the Mariners starting rotation in 2002.
Carlos Guillen's career took off with the Detroit Tigers, but his Major League career began in Seattle.
Tom Paciorek made his debut in the Majors in 1970 with the Los Angeles Dodgers, and he saw little action with L.A. when he played there until 1975. The Atlanta Braves had him next but released him in May of 1978, and by that time, he was 30 and had never been more than a platoon player. The Mariners would sign him days later, and the First Baseman remained as a platoon player, but he would see more action in 1980 and would have 114 Hits. That was good, but in 1981, he had an unexpected season.
After playing a decade in Japan with Yokohama, Kazuhiro Sasaki was a 32-year old rookie in Seattle, and with a decade of real experience, he easily won the 2000 American League Rookie of the Year Award. The former Central League MVP would finish third in the AL with 37 Saves.
