Are the commas in the right place?

894 Jenkins Blvd., Knoxville, Tennessee 37901 June 12, 2001

Or

894 Jenkins Blvd. Knoxville, Tennessee 37901 June 12,2001

Commas come in after a list, to break a sentence apart, or in a clause.

In this case it would be a list.

(I'm guessing this is an address followed by a date later on)
