For each day's notes, I'm going to try to give Ty Cobb's batting line from exactly 100 years ago.  He started his career in 1905 and started playing everyday in 1907, so I'll give his official batting line for his game from 100 years ago today.  All these data come from my database of all 3035 of Cobb's games.  Today's July 7, 2007, but Cobb didn't play a game on July 7, 1907.  So here's his line from July 6, 1907, instead:

A Century of Cobb:
July 6, 1907: at home vs. BOS; 2-for-4, double; opposing starter: Cy Young
