Thanks to ESPN.com’s new “roster analysis” page, which automatically updates as teams’ rosters change, we can keep track of various averages for each major league roster all season long.
Baseball’s fattest team? The Chicago White Sox (and it’s not even that close) , weighing in at an average of 221 pounds. The biggest culprits include the mountainous Bobby Jenks, generously listed at 275 pounds, the bulbous Jim Thome (255), and the voluminous Toby Hall (also listed at 255).
The thinnest team is the San Francisco Giants, weighing in at a scant 195 pounds on average, proving that not only are the Giants the lightweights of the Major Leagues when it comes to hitting, but that they are also the lightweights when it comes to actual weight. (Although now with 180-pound Dave Roberts heading to the DL, their rank may change).
As for the average height of baseball teams, we see that it does not vary much, with 29 out of the 30 teams having an average height of either 6-1 or 6-2. In dead last at 6-0 is the puny Houston Astros.
Baseball’s youngest team is, unsurprisingly, the Florida Marlins, with an average age of 27.2 years, while baseballs oldest team is a tie between the Boston Red Sox and the New York Mets, at 30.6 years of average age.
