Free agent lefty starter Randy Johnson announced his retirement on Tuesday, thus ending a 22 year career that will no doubt be re-visited in five years when he is enshrined in Cooperstown.  Johnson finishes with a record of 303-166, ranking second on the all-time strikeouts list with 4875. 

For the Giants, this means little.  He was great to have around last year and might have played a big role in the development of some of their younger pitchers (Jonathan Sanchez in particular).  However, he was a free agent and the team had moved on with decisions concerning their rotation. 

The impact of his career on Major League Baseball can’t be overstated.  Enjoy retirement, Randy.
