I checked out the baseball field when I first got here. It is in the northwest and was (as of last October) in reasonable shape. It kind of reminds me of a minor league / college park that would hold about 3-4,000 people. I am too old to play anymore (maybe senior slowpitch softball), but if you get anything together I could umpire. Prior to moving to Chengdu I was umpiring 80-110 games a year of fast pitch softball at the rec, high school, juco and club level in Florida. The basic rules of baseball and fastpitch softball are the same. I would freely offer my services just to get back into the game.
