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.

New York Yankees

Reynaldo Lopez has a 5.37 SIERA this year. He has also allowed opposing batters to post a 47.5% fly-ball rate and 33.5% hard-hit rate while mustering just an 8.5% swinging-strike rate.

And while the New York Yankees are certainly missing Aaron Judge, he is not the only reason New York ranks top-10 in both fly-ball rate (37.5%) and hard-hit rate (37.0%) against right-handed pitching this season.

Remember when Giancarlo Stanton was getting booed? Pepperidge Farm remembers. Well, today, Stanton's hard-hit rate is up to 43.2%, and his wRC+ is all the way up to 127.

Elsewhere, Didi Gregorius ($3,800) has a 12.7% strikeout rate, 44.7% fly-ball rate, and 38.4% hard-hit rate against right-handed pitching this year. And Aaron Hicks ($3,800) has a 38.6% fly-ball rate and 42.0% hard-hit rate in 2018.

Gleyber Torres ($3,600) has 50 RBI in just 74 games, and sports a 42.6% fly-ball rate to pair with a 42.4% hard-hit rate. Fellow young back Miguel Andujar ($3,400) has a 17.7% strikeout rate and 36.5% hard-hit rate as he leads the team in hits.

From the left side, Brett Gardner ($3,400) generally leads off for the Yankees against right-handed pitching, and he has just a 15.4% strikeout rate this year. Greg Bird ($2,900), on the other hand, will strike out his fair share. He hits the ball well, however, as he has a 49.6% fly-ball rate and 42.8% hard-hit rate in 2018.

Toronto Blue Jays

The Boston Red Sox have been unreal this season, but Drew Pomeranz has been the lone sour spot. He has an elevated 12.3% walk rate, and he fails to make up for that with just a 7.3% swinging-strike rate. Pomeranz has also been hit hard, having surrendered a 40.4% fly-ball rate and 38.1% hard-hit rate, good for a 5.08 SIERA on the year.

The Toronto Blue Jays are the perfect team to take advantage of Pomeranz's fly-ball tendencies. They rank second in baseball with a 38.8% fly-ball rate against southpaws this year.

Justin Smoak ($3,700) has posted a 44.2% fly-ball rate and 32.8% hard-hit rate this season. Aledmys Diaz ($3,400) combines contact with power with his 12.5% strikeout rate, 39.1%, and 33.2% hard-hit rate. And as for Teoscar Hernandez ($3,200), he ranks fifth in barrels per plate appearance this season.

Kendrys Morales ($3,100) boasts a 37.3% fly-ball rate and 42.5% hard-hit rate. Randal Grichuk ($3,100) has a 43.9% fly-ball rate and 34.3% hard-hit rate this year while fellow outfielder Kevin Pillar ($2,400) has an 18.3% strikeout rate, 36.3% fly-ball rate, 33.7% hard-hit rate, and the speed to swipe a bag or two as well.
