Baseball, uniquely, is a game with a tradition based in numbers. How many home runs in a season/career? How many stolen bases, wins, saves, etc. A trip to Cooperstown is a journey into the exploits of the greats of the past, most of which are explained with numerical records. There's an entire room dedicated to records.
Bryan Burwell believes baseball has such a credibility problem right now that every [recent] record should have a "giant asterisk placed next to it until someone shows us a list of names of the folks who failed baseball's tests for performance-enhancing drugs".
