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. With the split slates, we'll be focusing exclusively on the main slate beginning at 7 pm Eastern. Additionally, because the second half of the double header between the Los Angeles Dodgers and Colorado Rockies is not included in FanDuel's main slate, we will be omitting that, as well. Here are the teams you should be targeting in daily fantasy baseball today.

Washington Nationals

We've mentioned this several times this year, but Adam Morgan truly is showing some progress that should encourage the Philadelphia Phillies' brass. His 18.3% strikeout rate is significantly higher than his mark last year, so things are getting better. He's just not quite there yet, and he has a brutal matchup today with the Washington Nationals.

The next step for Morgan would be finding ways to limit hard contact. Opponents have a 36.2% hard-hit rate and 39.9% fly-ball rate against him, meaning that while his 18.5% home run to fly-ball ratio is inflated, it's going to be lofty, regardless. That's especially true at a dinger-friendly crib like Citizens Bank Park. If he can curtail that, he'll be a quality hurler; there's just still a bit of work left to be done.

With Ryan Zimmerman playing more of a platoon role since his return, we don't have a lot of data with which to judge his current form. In 65 plate appearances, he has a 29.2% hard-hit rate and 41.7% fly-ball rate, neither of which will turn any heads, but they also aren't terrible. That may mean his ball-bashing abilities against lefties are still in tact.

Zimmerman has a 39.0% hard-hit rate and 6.8% soft-hit rate versus southpaws this year after posting marks of 52.1% and 13.7%, respectively, last year. He's stuck to tourney duty if he bats seventh, but the ownership and pricing should both be favorable.
