The white ash tree used to stand tall, straight, and imposing. Its canopy painted the landscape in gold and maroon. It was the species you are most likely to encounter on a stroll through the New York and Pennsylvania woods. But now there are dead ash trees everywhere, devoured by a little green beetle, the emerald ash borer. Ash joins the ranks of over a million plant and animal species presently at risk of extinction.
Among native tree species, ash represents a tiny fraction of the continental woodlands. But there is one arena where ash has historically reigned: in baseball. Ash is probably best known as the preferred material for baseball bats — strong yet remarkably light.
Most of baseball history has been written with ash bats, from Joe DiMaggio’s 56-game hitting streak in 1941 to Roger Maris’s 61 home runs in 1961 to Mark McGwire's 70 homers in 1988. Babe Ruth swung ash bats weighing a whooping 46 ounces. Ty Cobb had his crafted for him by a coffin maker. Ted Williams used to travel to the factory of Hilerich & Bradsby, the maker of the Louisville Slugger, to select the lumber he wanted carved into his bats.
Today, not one major leaguer is swinging an ash Louisville Slugger in games. Baseball’s future will depend on other woods, mainly maple and birch. Because ash is a softer wood with a looser grain structure, it can be more susceptible to splintering or flaking. But in the barrel, the so-called sweet spot, the softer ash bats can flex upon contact, producing a trampoline effect on the ball. With maple as the predominant replacement and birch at a distant second, nothing can replace an ash bat.
The light grain in maple can disguise weakness. While ash bats crack, maple bats explode. This results in many more bats shattering and causing potential harm. The downside of birch is its softness. Hitting often leaves dents on the shaft of the bat. Birch is not nearly as flexible as ash, and according to some players “doesn’t sound as good.”
So next time you see a baseball bat shatter in a big game, it may be that ballplayer was forced to swing maple instead of ash. And it won't just be America's pastime that's changed. The demise of the ash tree demonstrates that real, visible, and consequential ecological catastrophes are playing out all around us.
