What was the Pine Tar incident with George Brett?
The umpires measured the amount of pine tar, a legal substance used by hitters to improve their grip, on George Brett's bat; the pine tar extended about 24 inches.
Was the pine tar extending about 24 inches on George Brett's bat illegal?
Yankees manager Billy Martin cited to the umpires a rule, stating that any foreign substance on a bat could extend no further than 18 inches from the knob.

Question: What happened to Brett after that?
