History[]

A young Aeropos training for baseball, with rats.
Walkov developed a unique two-handed pitching style while helping his ratcatcher father in a Macedonian village. This included launching the dead rats over the border into Greece, neighbor and historic rival.
This lead to him eventually signing for the Minsk Golems team where he became a superstar any team in the world would want.
Thanks to having a Macedonian speaker (Moe Szyslak) and Springfield not looking too far off the Macedonian looks, Walkov chose to move to the Springfield Isotopes. His popularity made Macedonian national costumes a trend in America. Eventually, after a betting scandal, Walkov signed off to another team.
