'Too' in this sentence

[Grammarholic]

Would you enclose the word 'too' in commas in this sentence?

I, too, am a fan of the New York Yankees.

When 'too' is used at the last word in a sentence, does a comma precede it? I see it both ways.

I am a fan of the New York Yankees, too.

Thanks.

Hi Grammarholic,

You seem to be eager to learn grammar. I highly recommend reading all "Grammar Girl" articles. (Visit Grammar Girl at http://tinyurl.com/2boh3oy.)

In answer to your question, please read the following:

Should we write, “He has the ball too” with no comma or “He has the ball, too”? Well, you can write the sentence either way. It’s up to you as the writer. A comma before the “too” gives the sentence just a slightly different meaning than the sentence without one.

...you could say, “I too like reading mysteries” or “I like reading mysteries too.” If, on the other hand, you want to emphasize an abrupt change of thought (1), you do use commas, which, among other things, are used to indicate pauses: “I, too, like reading mysteries” or “I like reading mysteries, too.” In these sentences, you are adding a pause to create emphasis.
