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 not be a part of this piece. You don't need me to tell you to get exposure to Coors.

Now, let's get to the stacks.

Cincinnati Reds

It's time to dial up exposure to The Queen City, as the Cincinnati Reds look like they could be the best stacking option on today's slate.

The Reds will face Chris Flexen of the New York Mets, who has been, well, bad. This year at the major league level, Flexen has walked 20 batters while only striking out 19, along with allowing a pile of juicy contact in 28 major league innings -- batters have rocked him for a 33.7% hard-hit rate and a 41.8% fly-ball rate.

One number that stands out in particular is Flexen's fly-ball rate against left-handed batters. Over 60 total lefties faced in 2017, he's allowed a 53.7% fly-ball rate, which borders on absurd, and is something we need to target.

And if there's one thing the Reds have, it's a ton of lefties with pop, especially this dude.

Against the St. Louis Cardinals earlier this season, Scooter Gennett went ding-dong FOUR times in one game. That'll do, donkey, and at $3,300, he's almost a must play. Joey Votto ($4,200) is a bit more expensive, but is also a great option, as is a third Reds lefty, Scott Schebler.

Priced down at $3,000 thanks to a recent injury and a July where he posted an absolutely dreadful 19 wRC+, Schebler has been a man on fire in August. So far, he's recorded a 45.8% hard-hit rate and a 33.3% fly-ball rate this month, which has led to a 1.215 OPS.

Those three lefties will all give you some strong exposure to a struggling right-hander.
