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.

Oakland Athletics

The one thing that has stopped us from stacking against A.J. Griffin in the past is a respectable, league-average strikeout rate. This year, though, his swinging-strike rate is lagging behind where it usually sits, and it's increasing the incentive to load up on his opponents.

Through Griffin's first two starts, his swinging-strike rate sits down at 7.6%. That's a good chunk below his mark of 9.1% in 2016, and it may even make his 19.5% strikeout rate appear due for some downward regression. When you struggle to get strikeouts while allowing a 51.7% hard-hit rate and fly-ball rate (where Griffin's at this year), hitters can leave the yard in a hurry, and that's what we want out of the Oakland Athletics today.

The A's offense has gotten off to a great start, ranking seventh in hard-hit rate and eighth in fly-ball rate thus far. A lot of that is due to Khris Davis doing Khris Davis things, but Yonder Alonso also looks like a completely new hitter. Over 24 balls in play, he has a 41.7% hard-hit rate and 45.8% fly-ball rate, showing that his offseason goal of lofting the ball more is paying off and making for some pretty swings.

He's just $2,600 on FanDuel, a price that doesn't reflect his new-found upside. Toss in the low pricing on guys like Matt Joyce and Jed Lowrie, and this stack starts to look pretty spicy.
