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.

Minnesota Twins

In 2018, Lucas Giolito has an elevated 11.3% walk rate, but that's arguably the least of his worries. His swinging-strike rate sits at just 8.4%, and he's allowed a 37.6% fly-ball rate. All of that adds up to a horrendous 5.32 SIERA.

The Minnesota Twins boast the ninth-lowest strikeout rate (21.4%) against right-handed pitching. The Twins also have the highest fly-ball rate in the game in that split, as they put the ball in the air on 39.1% of their balls in play. They also rank ninth with a 38.0% hard-hit rate against righties.

Jorge Polanco ($3,400) enters play with a 133 wRC+ against righties, thanks to just a 17.1% strikeout rate to go with his 38.9% fly-ball rate.
