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, Coors Field will be ignored for stacking purposes. You don't need my expert advice to tell you that's a smart play.

Now, let's get to the stacks.

Arizona Diamondbacks

Thanks to only the sixth rainout in the history of AT&T Park last weekend, Derek Holland's start was pushed back, which gives us a great stacking opportunity tonight with the Arizona Diamondbacks.

The 2017 season was a very long one for Holland. Over 135 innings, Holland recorded a ghastly 5.57 SIERA, which was built largely on an inflated walk rate of 12.0%. He paired that with a 38.4% hard-hit rate and 40.5% fly-ball rate. Righties really bopped Holland pretty good a year ago -- they nailed him for a 41.3% hard-hit rate, 43.7% fly-ball rate, and .574 slugging percentage. Ouch.

Paul Goldschmidt only has a .100 batting average so far in 2018, but he's bound to snap out of this soon, right? Priced down at $4,300, Goldschmidt blasted lefties for a .280 ISO, 49.5% hard-hit rate, and 38.3% fly-ball rate a season ago.

One dude off to the races so far in 2018 is A.J. Pollock ($3,900). With the platoon advantage in 2017, Pollock teed off for a .248 ISO and 32.0% hard-hit rate.

Sticking in the outfield, utility man Chris Owings ($3,200) is a bit cheaper but possesses plenty of upside. Owings showcased a solid .149 ISO to pair with a 40.9% fly-ball rate batting against southpaws.

If Goldy is too expensive for your stack, one super cheap option at the C/1B spot is J.R. Murphy ($2,100). The journeyman catcher nabbed the backup spot for 2018, and for his career (392 plate appearances), he's shown some nice punch with a .132 ISO, 30.8% hard-hit rate, and 37.6% fly-ball rate against opposite-handed hurlers.
