It's Crestfallen Day, but not to worry -- you can play FanDuel

After a 3-0 start to the 2015 season, the Colorado Rockies have their first day off before opening their home slate with a series against the Chicago Cubs.

Yes, that's right: it's Crestfallen Day. There are roughly 18-20 of these per season, and historically -- even when the Rockies have been bad, which is often -- they're the worst.

It doesn't have to be that way, though. Our friends at FanDuel have given us something to look forward to on off days (and every other day, really, but you need it today).

In case you've never played before, here's a quick tutorial on how it works:

And, here are the official rules. Now that you know how to play, here are a couple of tips:

• Use Baseball Press to check lineups. You don't want to pick a player who is benched for the day, obviously.
• How does a certain player perform against a specific pitcher? Does he historically hit well at certain parks? Does he own soft-tossing lefties? Checking player splits at Baseball-Reference is a really helpful tool, and it can make you some real money if you play your cards right.
