My review of High Heat: The Secret History of the Fastball and the Improbably Search for the Fastest Pitcher of All Time by Tim Wendel has been published at PopMatters.
The argument over which pitcher in US baseball is the “fastest of all time” is a fun one that never ends. Since the radar gun is a fairly recent invention, there is not an accurate way to compare the fastballs of early and mid-20th century pitchers like Walter Johnson, Lefty Grove, and Bob Feller with those thrown by today’s pitchers like Joel Zumaya and Billy Wagner. Throw in the fact (pun intended) that radar guns are not as accurate as we are led to believe and you have plenty of fodder for the informed and not-so-informed to make all the claims and suppositions they want.
As a baseball fan, this was a fun book to read.
