Quick sites that I read.

Sometimes it's a good idea to post some of baseball links that I follow. Gamer Baseball Todd Coburn posts almost daily with quick words of wisdom. He also runs a Best of the West catcher's camp and works with America's Baseball camps in Nevada, Arizona and California. Not to mention the best catcher and coaching handbook in print. Foreword by Ron Polk!
