Very enjoyable. This is definitely a low-key but authentic book. The author is a New York Times columnist and author of other significant books.
I first became fascinated with baseball when we moved to Chicago in 1947. Our neighbor across the street, our babysitter's father, had the first TV in the neighborhood, and people would troop in and out of the house to watch whatever was on. During the summer, it was either Chicago Cubs or Chicago White Sox baseball, and when I wasn't watching it over there, I was listening to it on the radio.
In my lifetime, I've read at least fifteen books on baseball and consider myself to be a fan, though I'm not a fanatic, my interest has ebbed and flowed over the years, and I've rarely been partial to one particular team. (Probably the Cubs more than any other, but far from always.) I consider myself to be conversant in baseball history. I also know when enough is enough, so years go by between books.
Baseball has been around for a very long time, and there is much to learn about it. Particularly intriguing to me is the sequences of changes that came to the game: in rules, gear, and the business aspects of the game.
Although I still love to watch a good game when I can, much of the modern game has been spoiled for me by certain modern developments; and I don't think of myself as a purist or an old-fashioned fuddy-duddy. The designated hitter is simply a bad idea for a lot of reasons, one of the worst being that it's been implemented only in the American League, which affects the whole style of strategy. Furthermore, in interleague play, the visiting team is always at an additional disadvantage because of playing according to the rules of the home team. I also detest all the noise and additional tomfoolery that takes place between innings. Furthermore, I dislike the tendency that has developed for there to be increasingly more home runs rather than strategic play, and the specialization of pitchers that leads to pitchers pitching five or six perfect innings and then being taken out because he's reached some arbitrary pitch count. It seems like more often than not, a pitcher who has been doing fine will walk someone in the fifth or sixth inning, be taken out, and the next batter will smack it into the next county on the first pitch of the "relief" pitcher. (Some relief.) Another thing I dislike about modern baseball is the wild card that leads to extended playoffs so that instead of seeing the World Series in early October, when they are delightful, they extend sometimes to November 1, when players and fans alike might be bundled in winter wear. Baseball is supposed to be a summer game.
Nevertheless, when baseball is good, it's a beautiful experience, especially when watched from a seat along the first-base side in the ballpark. And this remains true whatever level the game is played at: major leagues, minor leagues, college, high school, and even little league.
If you think you already know a lot about baseball, I daresay there are still some tidbits you can pick up from reading George Vecsey's book.
