Tiger Shoots a 61 at Bridgestone.....What Can You Compare That To?

Yesterday Tiger shot a 61 in the  2nd round of the Bridgestone  to pull away from the field with a 7 shot lead. As he  reached the tee on the 15th hole he was flirting with the lowest score(59) ever recorded In a PGA  Event. It is noteworthy that  his  score  tied his lowest PGA  score ever.
   So to to put things in perspective, what can we  equate shooting a 61 in golf  in a PGA Event  to  accomplishments  in other major  sports? For  instance is it comparable  to scoring 60 points in an NBA game?  Or a quarterback  passing for 500 yards in an NFL game?  A  baseball player  hitting 4 home runs in a game A hockey  player scoring   5 goals in a game ? The comparisons can go on and on.
   All I  can tell you is for one day , Tiger was Tiger! Let's see if  he can keep the momentum rolling.
   Wow!
