The Tigers were owned and administered by the local Mercuries Corporation whose then chairman Chen He-dong (陳河東) was a classmate and a close friend of Brother Hotel and Brother Elephants's chairman Hung Teng-sheng (洪騰勝) in the National Taiwan University, and immediately promised to fulfill Hung's wishes to form a Taiwanese professional baseball league in 1988.

This team was established accordingly in 1989 and took the now-demolished Taipei Municipal Baseball Stadium as its home throughout its history.

Because the Mercuries Corporation itself was inexperienced in running sports clubs, in 1988 and 1989 it was mostly Hung Teng-sheng that built up the Tiger's roster as well as managing most business, with Chen He-dong sponsoring the necessary fund.

[citation needed] In the 1990 Taiwan Series, the Tigers were defeated by the Wei Chuan Dragons 2-4, and except for winning the 2nd place in the upper 1994 and lower 1995 half season, this club had never gained an upper-half seat in the final seasonal standings throughout its history, as well as long time being the least popular and poorest attended CPBL team throughout its lifetime.

After long time loss the Mercuries Corporation finally closed down the team after the 1999 season ended.
