Bradford Doolittle's new Kansas City Star articles (entitled Stat Guy are great. He takes a current baseball topic (usually involving the Royals), and puts a sabremetric twist to it. Bradford also has a great blog with his brother where they discuss both Missouri MLB teams.
In the latest Stat Guy, Doolittle compares the recently resurgent Tampa Bay Devil Rays to the struggling Royals. Royals fans have yearned for a Rays-like run all season. Doolittle compares the offense of the two teams. Both are practically equal. He then compares pitching, and finds that it is also pretty much equal. The difference seems to be in the defense.
Both teams put a large number of balls into play. The Devil Rays, however convert a greater number of those into outs. At the beginning of the season, the Royals were touted as a great defensive team. However, the defense (like the pitching and offense) has been disappointing.
