Stacking can be a controversial topic in many daily fantasy sports, but you can count baseball as a glaring exception. Here, it's universal.

Using multiple players on the same team on a given day presents you with the opportunity to double dip. If one of your players hits an RBI double, there's a good chance he drove in another one of your guys. When you get the points for both the run and the RBI, you'll be climbing the leaderboards fast.

Each day here on numberFire, we'll go through four offenses ripe for the stacking. They could have a great matchup, be in a great park, or just have a lot of quality sticks in the lineup, but these are the offenses primed for big days that you may want a piece of.

Premium members can use our new stacking feature to customize their stacks within their optimal lineups for the day, choosing the team you want to stack and how many players you want to include. You can also check out our hitting heat map, which provides an illustration of which offenses have the best combination of matchup and potency.

Now, let's get to the stacks. Here are the teams you should be targeting in daily fantasy baseball today.

Washington Nationals

There are too many good stacking options on tonight's slate to settle for one that will come with high ownership in a tournament. There's a good chance that will wind up being the Washington Nationals, so try to monitor the public to see whether they're flocking toward the Nats. Even if that does happen, though, this is the ideal team to stack in cash games.

They're going up against Andrew Cashner, who enters his 11th start of the year with a 5.90 SIERA. He still has more walks (11.4%) than strikeouts (10.2%), and the results are finally starting to align with the peripherals. He has done a good job of limiting hard contact, but in cash games, we want to focus on maxing out plate appearances and getting volume. Targeting a low-strikeout, high-walk pitcher like Cashner accomplishes that goal.

If you want to avoid Cashner's ground-ball ways, the easiest thing to do is target left-handed batters. They have a 41.5% fly-ball rate against him, which adds some upside to our volume. As you know, the Nationals have a few lefties who can (quite literally) do some damage.

Beyond Bryce Harper and Daniel Murphy, we may get another lefty near the top of the order depending on what the Nationals do in the two hole. They used Wilmer Difo there yesterday, though he may return to the bench with Murphy, Anthony Rendon, and Trea Turner all likely to play. That could force Brian Goodwin back up to the second spot, where he had been hitting against righties prior to Thursday. Check the Nationals' lineup once it's out, but that two hole figures to be a big source of value on tonight's slate.
