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 Mets

Jeremy Hellickson will be making his first start of the year for the Washington Nationals, and that makes the New York Mets the night's top stacking option.

Hellickson suffered through an awful 2017 campaign. Over 164 innings pitched, the veteran right-hander was blasted for a 5.37 skill-interactive ERA (SIERA) and 43.8% fly-ball rate. It doesn't appear that Hellickson is fooling anyone as he recorded a mere 13.8% strikeout rate a season ago, and it was particularly bad against left-handed bats, who torched him for a .507 slugging percentage, 50.6% fly-ball rate and 2.01 home runs per nine innings pitched (HR/9).

It's time to dial up the Mets' lefties, and this dude is ready to pop off.

Michael Conforto ($4,000) absolutely destroys right-handed pitching and should be the anchor of a Mets stack. Last year, Conforto cruised to a .292 isolated power (ISO), 40.7% hard-hit rate, and 38.7% fly-ball rate against righties.

Another lefty to consider is Jay Bruce ($3,300), who also can rip 'em deep. Bruce got to righties for a .271 ISO, 43.0% hard-hit rate, and 46.6% fly-ball rate in 2017.

Brandon Nimmo ($2,800) is a solid third option to consider as part of the stack. Nimmo showcased a .377 wOBA and 38.5% hard-hit rate a season ago against right-handed pitching, and he hit leadoff Sunday against a righty.
