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.

Boston Red Sox

Marco Estrada has always been a fly-ball pitcher, but he's taken things to a new level this year as he's allowed a 54.2% fly-ball rate to this point. That, combined with a 33.5% hard-hit rate and a strikeout rate that has plummeted to 17.3%, is the reason that Estrada's SIERA has soared to 5.05 in 2018. Especially in the confines of Fenway Park, the third-friendliest park for offense in baseball, a high fly-ball rate is a death sentence.

Even without the park factor, the Boston Red Sox are first in baseball in wRC+ against right-handed pitching. Their 5.50 implied team total is completely justified and stands as the highest on the main slate, outside of teams playing at Coors.

Mookie Betts ($5,500) and J.D. Martinez ($4,500) are first and third in wRC+, respectively, although you will want to check if Betts plays as he is dealing with side tightness.

Dropping down a little in price, Andrew Benintendi ($4,200) has a career 126 wRC+ against right-handed pitching. Fellow lefty Mitch Moreland ($4,000) has hit third or fourth since Hanley Ramirez's release, and he has a 40.4% hard-hit rate this year.

For cheap exposure, you can use Dustin Pedroia ($3,300), who has made a living out of peppering the Green Monster for extra-base hits.
