One of baseball's most expert commentators is leaving his home of 20 years, ESPN -- the place that made him a star.

Peter Gammons, an analyst best known for his clear, spot-on commentary of Major League Baseball players and trends, announced Tuesday that he is leaving the sports network for the MLB Network this week, according to a report at ESPN.com.

Peter Gammons has been off the air since suffering a brain aneurysm last June, and boy do I miss him. Don't get me wrong; Gammons' substitutes on ESPN's Sunday Night Baseball have done a good job. But he was one of the few people on that program and on Baseball Tonight that you could trust to give insightful analysis and insider information that wasn't full of bluster, catch-phrases, and smugness.

So this is good news: According to ESPN, Gammons will return to the channel on a part-time basis, starting Wednesday night. He'll appear from Fenway Park for both the 6 PM SportsCenter and the 7 PM edition of Baseball Tonight. He will be scheduled for further appearances as he becomes more comfortable. Good to see Peter back, especially considering it's been less than three months since his surgery.
