Baseball A B C

In two new board books, youngsters learn all about numbers and letters via major league baseball. In Baseball ABC not only will readers pick up on the basics of the game, such as ""home plate"" for H and ""shortstop"" for S, but they can also glean history lessons from such examples as ""Babe Ruth"" under B, ""Yankee Stadium"" and ""Yogi Berra"" under Y and the infamous left field wall at Fenway, the ""Green Monster"" under G. By contrast, Baseball 1-2-3 is a straight read up to the number 10, with five base runners featured for the number five. Vivid photographs of actual major league players and their official gear will introduce young fans to the world of baseball today. ( Mar.)
