Bad luck ...
Years ago a good friend and teammate was a high pick of the Yankees. Talk about blocked. He was AAA Player of the Year. He was called up in September. Getting out of his car at the Columbus airport he stepped in a pothole and badly sprained his ankle. Season over.
The next season Rod Carew wasn't traded to the Yankees because they wouldn't give up my friend. His agent told him if the trade went through he wou,d be starting in left for the Twins. He had another great season in AAA.
He was told to report to the Yankees as soon as the AAA playoffs were over. He got hit by a pitch breaking his wrist. Season over. He never fully recovered. The following season he developed another medical issue. Two prospects who were behind him were eventually called up. They both had productive MLB careers. Two years later he was out of baseball.
