I'd call it a tie.
Yes, Kirby got the rings, but Rod got the batting titles. They were both best at their position for a long time.
But Kirby never had to play for Calvin Griffith.
Kirby was the first guy to break the 3 million a year barrier. He was valued by management, and had a better team to play with than Rod.
Rod got traded because Griffith wouldn't pay him, and the guy would be an All-Star the next 6 seasons in Anaheim.
Pohlads were cheap, but not Calvin Griffith penny-pinching cheap. They went out an got a Blyleven, or a Morris, and put their teams over the hump. Calvin would shed stars once they became too pricey, replace them with our favorite user name, Hosken Bombo Disco, although Disco was really Willie Norwood. Hell, he even dumped Killebrew.
Impossible to compare really.
