GRANDMAS AT BAT

From the new Caldecott medalist, a third ``I Can Read'' book about Pip and her squabbling grandmas. The Stings' coach has chickenpox—and unless Pip and her team come up with a substitute, they won't be allowed to play. Both grandmas volunteer; their constant bickering and mutual competing almost prevents the Stings from practicing, until one kid complains, ``Your Grandmas are driving us bananas!'' and another points out that ``The coaches are hogging the field!'' Finally leaving the team in peace, the grandmas find another way to help: at the big game, it's their cheerleading that spurs the Stings to victory. Baseball action and the amusingly caricatured grandmas are deftly drawn; best, the funny, true-to-life dialogue is sure to entertain beginning readers. (Easy reader. 5-8)
