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.
Our MLB DFS heat map 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 to identify the slate's best bats.
Let's look at the top stacks for this main slate, which starts at 1:07 p.m. EST.
Arizona Diamondbacks
The Arizona Diamondbacks are the standout offense on today's four-game main slate. Arizona boasts a 5.56 implied total in their home clash with Chase Anderson. No other offense is above a 4.86 clip.
Anderson, a right-hander, has been someone we've stacked against fairly often over the past few years, and he's putting up some terrible numbers so far in 2023, struggling to a 5.24 SIERA and 12.5% strikeout rate. Yes, please.
Corbin Carroll ($3,600), Ketel Marte ($3,400) and Christian Walker ($3,300) are three of the slate's top six bats, according to our model.
Carroll is going to be a core piece for me. He's more than lived up to his prospect hype, popping 9 homers with 16 steals. He's one of the better power/speed threats in the game and offers big-time upside each day. A season after hitting 36 dingers, Walker owns a 42.7% fly-ball rate and has 12 jacks. Marte, a switch-hitter, has eight homers and six steals, although he's been better versus left-handers.
Arizona also has some modest-salaried bats we can turn to -- specifically Pavin Smith ($2,700) and Josh Rojas ($2,700) -- which is crucial on a slate where Kevin Gausman ($11,100) is in his own tier at pitcher. Smith is forecasted to hit leadoff and has mashed his way to a .363 wOBA against righties.
Lourdes Gurriel ($3,500) and Geraldo Perdomo ($3,000) are worth a look, especially if Perdomo gets moved out of the nine-hole.
New York Mets
After Arizona, things are pretty wide open. You can make a case for a few teams, but no one is in a true smash spot. I'm going to opt to plug in some New York Mets.
While the Mets have underwhelmed offensively this season, they're still 15th in wOBA (.319) and have a juicy matchup versus Taijuan Walker, who has pitched to a 4.83 SIERA and 18.9% strikeout rate. Lefties (.350 wOBA) and righties (.340 wOBA) are both finding a lot of joy versus Walker, so we have flexibility with the Mets.
The Mets have just two bats salaried above $3,200 and can fit nicely alongside Gausman. Those two high-salary bats are Pete Alonso ($4,200) and Francisco Lindor ($3,500). Both are excellent options if you have the salary. Alonso is sporting an eye-popping .418 expected wOBA with 20 taters and may be en route to a career-best campaign, which is saying a lot given how good he's been in his career. Lindor has donged in two of the past three games.
Outside of those two, Brandon Nimmo ($3,200), Brett Baty ($2,700), Jeff McNeil ($2,700) and Starling Marte ($2,700) are the Mets I'm most into. Baty is off to a meh start but will have the platoon advantage against Walker. Nimmo will likely be atop the order while McNeil is projected to hit third. Nimmo has recorded a .360 expected wOBA and 37.9% hard-hit rate, the latter of which would be a career-best mark.
