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

Jorge Lopez will be making just his 8th career start this Friday night. He's struggled this year despite what his 3.72 ERA may lead you to believe. Lopez has a sub-par 9.4% swinging-strike rate, an elevated 11.0% walk rate, and an atrocious 43.3% hard-hit rate surrendered.

The Minnesota Twins rank 10th in walk to strikeout ratio against right-handed pitching. They also rank 2nd in fly-ball rate against right-handed pitching (39.2%) and 8th in hard-hit rate in that split (38.0%).

Eddie Rosario ($3,400) has been a lone bright spot for this Minnesota lineup with Eduardo Escobar traded away. He's got a 125 wRC+ against right-handed pitching thanks to limiting his strikeout rate to a 17.5% clip while maintaining a 45.9% fly-ball rate and 37.8% hard-hit rate. Tyler Austin ($3,200) has got a 36.8% fly-ball rate and 35.0% hard-hit rate this year.

Joe Mauer ($3,100) says he may retire after this year. He's had a tremendous career, and while he's not in his prime at age 35, he's still got a 14.4% strikeout rate and 44.7% hard-hit rate against right-handed pitching in 2018.

Jorge Polanco ($3,000) enters play with a 130 wRC+ against right-handed pitching. That includes just a 16.9% strikeout rate and 40.5% fly-ball rate in that split. Jake Cave ($2,600) has a 117 wRC+ against righties, thanks in part to a 38.5% hard-hit rate. Max Kepler ($2,300) has terrific stats against right-handed pitching, including a 12.2% walk rate, 14.8% strikeout rate, 47.0% fly-ball rate, and 37.9% hard-hit rate.
