I had to go to summer school for failing gym

I don't follow baseball, or any sport for that matter, but I feel I should have at least a faint wisp of working knowledge on this*. Please tell me, what exactly is going on with the Red Sox right now? Are they having a really good season or something? Explain in layman's terms, if you please. Large print optional.




_{* Understand, the only reason I happened to watch any of the 2004 World Series winning games was because the cast of Murder In The Cathedral, which I was in, would rush to someone's TV-having house after the rehearsals/performances to watch the games, and my social options were to go along or sit home alone, so I went along. But after that I forgot all about baseball.}
