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.

As always, the Coors Field game will be ignored for stacking purposes.

Now, let's get to the stacks.

New York Yankees

The New York Yankees will face a pitcher tonight that has a respectable 10.1% swinging-strike rate while only allowing hard contact 26.6% of the time. So why are we stacking against Rafael Montero of the New York Mets?

Well, he can't throw strikes.

This has been a recurring theme in his career, which has continued so far this year (11.3% walk rate). If we combine that with a .518 slugging percentage allowed to right-handed hitters, it could be a tough night in the Bronx for the young hurler.

Aaron Judge is a name many DFS-ers will target -- even with his second-half struggles -- but this stack should start with Gary Sanchez. The Yankees backstop is hitting 34 points higher against righties (.277 versus .243, respectively), and certainly loves hitting in Yankee Stadium. This year, Sanchez owns an .899 OPS at home versus a road split of only .800, along with a 33.0% fly-ball rate and 36.1% hard-hit rate, with has produced a 28.1% home-run-to-fly-ball rate at Yankee Stadium.

Hitting from the left side of the plate, both Brett Gardner and Aaron Hicks are in good spots at the top of the lineup. With all those free passes, it could be a green light to steal, and Mets catcher Travis d'Arnaud is one of the worst in the league with only an 18.2% caught-stealing rate (62nd in baseball).
