He currently plays for the Sydney Blue Sox in the Australian Baseball League.
Koo is a left-handed pitcher despite being born right-handed. As a child, he suffered an injury which forced him to become left-handed. He broke his right arm so badly, so he had to use his left hand. Koo attended Hanyang University.
Koo began his professional career in 1993 with the Hanwha Eagles of the Korean Baseball Organization. In 1996, he won both a Gold Glove Award and the MVP of the KBO with a 1.88 ERA, 18 wins, 24 saves and 183 strikeouts in 139 innings pitched.
I flew a kite, I held on tight to its string
Each time I go anywhere, I held on tight
In the middle of the night I woke up in fright
Thinking maybe in my dream I let go my kite
When I was in a restaurant talking to my friends
Watching their mouths move faster and faster
I thought of the kite that was flying the sky
And made sure that my hand was holding the string
That was long time ago
Many skies went by since then
Now my hands stopped holding anything
And I've learned to take a walk instead
Then one day in an evening light
I saw something strange shining bright
The sky was dark with swarms of larks
And in the midst of it all, yes, it was my kite
How did the kite get there? I never know
Floating away among the clouds to where nobody knows
I held my gun with both my hands
Slowly aiming at the shining dot
The shot went off, that dot blew off
