Zachary Levine tweeted a link to the St. Petersburg Times' Marc Topkin's post on the Rays' schedule for 2013.
While we, of course, don't know the Astros' schedule, we do know that the Astros will play the Rays at home in a four-game series from July 1-4 (as Levine notes, this will be the first time the Astros have played at home on July 4 since 2007), and in Tampa from July 12-14.
I've been curious as to whether The Schedulemaker will throw the Astros some holiday home game bones to boost attendance. Looks like the Astros do get at least one holiday at home.
UPDATE: The schedule will be released at 12pm Central.
