This applies to at least somewhat popular sports. (i.e., not sports that only really get attention, if any at all, during Olympic time).
1. Golf
2. Soccer/Association Football
3. NASCAR/Indy
HM: Baseball, I love to play it, but I couldn't really. The last time I followed it closely was during the White Sox World Series season.
Basketball isn't as boring, as I really don't like it.
