Chicago Cubs history unpacked — June 29

Free of charge for the discerning reader.

Happy birthday to Frank Schwindel, and a mighty host of others.

Today in baseball history, in 2004 – At Bank One Ballpark, the Diamondbacks' 40-year-old fireballer Randy Johnson records his 4,000th career strikeout to become the fourth player in major league history to reach the plateau. The "Big Unit" needs fewer innings (3,237.1) than Nolan Ryan (3,844.2), Roger Clemens (4,151) or Steve Carlton (4,991.1) to accomplish the feat, and other stories as well.
