The two best teams in MLB* play a three game series that begins today. The 40-21 Texas Rangers, with the second-best record in baseball, are in Tampa to face the 46-19 Rays, who have the best record in baseball.
* If you want to be pedantic you can say that they are the two teams with the best records in MLB, but not necessarily the two best teams. Fangraphs, for example, projects the Rangers to have the 16th best record from now to the end of the year. However, that makes for a longer, more awkward and less punchy headline.
