Asterisks, shmasterisks. I’m not a sports fan who’s concerned with the record books. Actually, I’m not much of a sports fan…
If the asterisk is important to you, YF at Yanksfan vs Soxfan offers a more comprehensive list of notations. After all, factors other than steroid use can influence the records. Here’s a subset:
* = Steroids
! = Amphetamines
$ = Gambling
|| = Cocaine
~ = Alcohol
? = Before integration
# = Before expansion
Go read the entire !@#$% list.
