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.
Los Angeles Dodgers
The Los Angeles Dodgers are once again a fantastic stacking option as they have the night's top implied total (5.37) in a clash with Osvaldo Bido.
Bido, a righty, has only 19 MLB innings to his name, and he's been respectable, sporting a 4.44 SIERA. But his swinging-strike rate is just 6.3%, and he posted a meh 23.5% strikeout rate in 55 1/3 innings in Triple-A this season.
Anyone in LA's lineup is worth a look. The only negative with the Dodgers today is salary as they have five players with salaries of at least $3,600 -- Mookie Betts ($4,400), Freddie Freeman ($4,200), J.D. Martinez ($3,800), Max Muncy ($3,700) and Will Smith ($3,600). Of that group, Muncy is the one I'm most into as he has recorded a .359 wOBA, 42.6% hard-hit rate and 50.0% fly-ball rate versus right-handers.
David Peralta ($2,600), James Outman ($2,700), Jason Heyward ($2,500) are useful salary-savers, and all three will hit from the left side if they're in the lineup. Righty Miguel Vargas ($2,600) also needs to be on the value radar.
Atlanta Braves
Much of what I just said about the Dodgers also applies to the Atlanta Braves; they're good, in a smash spot and have several high salaries.
Atlanta (5.20 implied total) is facing right-hander Cal Quantrill. Through 62 2/3 innings in 2023, Quantrill has struggled to a 5.57 SIERA and 12.3% strikeout rate. Lefties have hammered him to the tune of a .380 wOBA and 1.40 dingers per nine. That's where I'll focus, although all of Atlanta's bats are firmly in play.
Lefties Matt Olson ($4,300), Ozzie Albies ($3,700), Michael Harris II ($3,300) and Eddie Rosario ($3,000) offer big-time upside. Olson has slugged his way to a .424 wOBA and 50.0% fly-ball rate with the platoon advantage this year.
Despite Quantrill's splits, right-handers Ronald Acuna Jr. ($4,800), Austin Riley ($3,600), Marcell Ozuna ($3,200) and Sean Murphy ($3,800) are plenty viable, too. Riley has put up a .390 wOBA across his last 13 games.
Cincinnati Reds
The Cincinnati Reds have been handed a 4.95 implied total for their matchup with Josiah Gray.
Gray, a right-hander, is a little scary to stack against because he can get whiffs, with his career swinging-strike rate at 11.4%. But when batters make contact, they do damage. For his career, Gray has surrendered 1.97 homers per nine and a 46.4% fly-ball rate.
I have a ton of interest in modest-salaried lefties TJ Friedl ($3,400), Joey Votto ($3,100) and Jake Fraley ($3,300). Friedl will likely be atop the lineup, and he's got a .361 wOBA and 40.4% fly-ball rate versus righties this season. Fraley (.396 wOBA and 42.5% fly-ball rate) and Votto (44.4% hard-hit rate and 66.7% fly-ball rate) are also doing work against righties.
Elly De La Cruz ($4,000), Matt McLain ($3,800), Spencer Steer ($3,600) and Jonathan India ($3,500) make a lot of sense, too. Lefty Will Benson ($2,700) is a quality value piece who has posted a .371 wOBA against righties.
Other top options: Minnesota Twins (vs. Alec Marsh), New York Mets (at Tommy Henry)
