Stacking is an integral part of daily fantasy baseball. Correlation drives upside, giving your lineups a slate-winning ceiling when your stacks explode.

This piece will do the digging and the dirty work each day to determine which stacks are worth rostering on FanDuel's main slate. While we want upside, we also need to factor in game theory, especially in a sport as random as baseball.

The MLB DFS heat map at numberFire is a quick way to get a feel for the overall slate and which offenses are in a good spot. You can also check out our daily fantasy baseball projections -- which are powered by numberFire -- to identify the slate's best bats.

Let's look at the top stacks for today's main slate.

MLB DFS Stacks

New York Mets

Implied Total: 4.85 | Opposing Pitcher: Roddery Munoz

There hasn't been a ton to love about the New York Mets this season, but they just scored 10 runs last night and are in a great spot to carry that over to tonight.

They'll face Roddery Munoz of the Miami Marlins, who has really served up some meatballs in his time in the big leagues. Hitters have been able to barrel the ball a whopping 21.2% of the time and have a 48.1% hard-hit rate against him. His 48.1% fly-ball rate also means he's likely going to allow a lot of homers.

The Mets' bats we'll want to target are the guys right at the top of the lineup. Pete Alonso ($3,500) isn't having quite as good of a season as he did last year, but he still has a .227 ISO. Brandon Nimmo ($3,000) gets on base at a .341 rate, which will help set the table for other hitters.

J.D. Martinez ($3,000) has been a disappointing signing, but he still has a 16.2% barrel rate and a 42.3% fly-ball this season. That bodes well against Munoz.

The other options for the Mets are Francisco Lindor ($3,600) and Starling Marte (3,300). Lindor does benefit from batting leadoff, but Marte has been better, with a 126 wRC+ this season.

Most of the Mets bats come in with reasonable salaries, making them an easy stack to fit into lineups tonight.

Los Angeles Dodgers

Implied Total: 4.84 | Opposing Pitcher: Michael Lorenzen

On most slates this season, we'll want to stack the Los Angeles Dodgers, and tonight is no different. They have the second-highest implied team total behind only the Mets.

The Dodgers will go up against Michael Lorenzen on Thursday. Lorenzen hasn't been terrible this season, but he is due for some regression. His 3.05 ERA is way lower than his 4.87 SIERA, and he's also sporting a high 11.8% walk rate.

We'll want the Dodgers' superstars in this stack -- all of whom have been mashing this season. Shohei Ohtani ($4,500), Mookie Betts ($4,200) and Freddie Freeman ($3,800) all have a wOBA above .400 against right-handed pitchers. Ohtani is also sporting a 204 wRC+ against righties, the second highest in baseball.

The Dodgers also have one of the hottest hitters in baseball in Teoscar Hernandez ($4,000). He was named NL Player of the Week after hitting .360/.429/.960 last week and has added another dinger this week.

It's definitely a good route to go to get some Dodgers in your lineup on this smaller slate, as they likely possess the most upside with their power hitters.

Minnesota Twins

Implied Total: 4.75 | Opposing Pitcher: Luis Medina

Rounding out the best stacks, we'll have the Minnesota Twins at home tonight in a good spot.

Minnesota will face Luis Medina, a pitcher who is inexperienced at the major league level. In two starts this season, he has allowed free passes 15.6% of the time plus a hard-hit rate of 48.4% and a fly-ball rate of 48.4%.

As a team, the Twins have a 106 wRC+ with their active lineup against righties. That's the eighth best in baseball.

Trevor Larnach ($2,900) has a .330 wOBA against righties this season, making him a value as a leadoff hitter. Ryan Jeffers ($2,900) is the same salary and has been teeing off against righties to the tune of a .257 ISO.

It's nice for Minnesota to get Royce Lewis ($3,800) back into the lineup. He's been excellent so far with a .542 wOBA and five homers in just nine games played this season. Carlos Correa ($3,200) is also a great value, as he's experiencing a bounce-back season with a 131 wRC+.

This Twins foursome requires $12,800 in salary, compared to $16,500 for the recommended Dodgers' bats above.
