Yesterday I attended a meeting of the Lefty O’Doul chapter of the Society for American Baseball Research (SABR), held at the George Krevsky Gallery on Geary Street in San Francisco. George — both charming and a great baseball fan — and his staff put together an annual show of art depicting baseball. This year’s exhibition, “Building a Team,” runs through June 7. Check it out if you can; the show is full of evocative works.
