Baseball is an etymologist's delight. The game coins words and phrases faster than Mark McGwire hits home runs (a.k.a. dingers, taters, round-trippers, four-baggers), and much of what begins as baseball-specific verbiage seeps into common usage. But why exactly is a high, lazy fly ball called "a can of corn," a pop-up that falls between the infield and the outfield a "Texas leaguer," a vicious curveball "Uncle Charlie," a poke that bounces off the plate a "Baltimore chop," and the minor leagues "the bushes"? Paul Dickson explains them--and about 7,000 more terms and expressions, names and events--in a wide-ranging work that's as much fun to browse through as it is specifically useful. Like its 1989 predecessor (which only sent 5,000 entries to the plate), the Dickson Baseball Dictionary arranges everything alphabetically, supplies definitions, offers examples, provides cross-references, and, most fascinating of all, traces word and phrase origins. As references go, it brings out the "lumber," looks "yard," and pretty much "touches 'em all." --Jeff Silverman
