The record-setting season of 1998 has already seen a number of appreciations, from Bernie Milasz's pictorial Celebrating 70 to Mike Lupica's Summer of '98. Now McNeil (The King of Swat) compares the 1998 heroics of Sosa and McGwire with Ruth's 60 and Maris's 61. Placing each record in historical context, he considers each slugger's background and personality, the era's pitching quality, the size and character of the ball parks, and the variables of day/night play. The extensive statistics and appealing sidelights add to McNeil's analysis. Sports students and their libraries especially will want this.--Morey Berger, St. Joseph's Hosp.
