3 Daily Fantasy Baseball Stacks for Wednesday 6/30/21

Stacks are the backbone of cashing daily fantasy baseball lineups. Correlation drives upside, creating the potential to place high or even win GPPs when your selected stacks explode offensively.

This column will do the digging and the dirty work to determine which stacks are worth rostering each day. Scoring upside will fuel the stacks that get the nod. Sometimes that will lead to chalky selections, but contrarian stacks will get their fair share of love too.

In addition to utilizing the touted daily stacks in handbuilt lineups, numberFire premium members can throw these highlighted stacks into an optimized lineup using our DFS Sharpstack tool. Our hitting heat map tool is also available to premium members looking for more stacking options. It provides valuable info such as implied total, park factors, and stats for identifying the quality of the opposing pitcher.

Let's take a look at the top stacks on today's main slate.

Cincinnati Reds

If the article summary hooked you, I'll spare you the suspense of waiting for the mystery contrarian stack. It's the Cincinnati Reds. Stacking against Joe Musgrove is a recipe for veering away from the masses. He's been excellent in his first year with the San Diego Padres. Pitching at Great American Ball Park is a challenging endeavor, though.

The ballpark affectionately deemed Great American "Small" Park is a homer and run-scoring haven. According to the park factors at FantasyPros, it has the second-highest park factor for runs (1.106) and is first for homers (1.347). The Reds have done an outstanding job of taking advantage of their cozy confines.

According to FanGraphs, the Reds rank sixth in weighted runs created plus (119 wRC+) at home, tied for second in isolated power (.210 ISO), and second in weighted on-base average (.353 wOBA). Thus, stacking the Reds is an endorsement for their home-hitting exploits rather than the belief Musgrove's a favorable matchup.

My favorite stacking options include Joey Votto ($2,900), Jesse Winker ($3,900), and Nick Castellanos ($4,300). Votto sports a .224 ISO and 135 wRC+ against righties this year and a .229 ISO and 125 wRC+ at home. Winker's ripped righties for a .329 ISO and 197 wRC+, and he's responsible for a .308 ISO and 175 wRC+ at home. Finally, Castellanos has amassed a .256 ISO and 172 wRC+ against righties, and he's been unstoppable at home with a .410 ISO and 238 wRC+.

Houston Astros

I'm bewildered by Matt Harvey continuing to get starts for the Baltimore Orioles. He has a 9.31 ERA and 5.23 skill-interactive ERA (SIERA) in his last five starts lasting only 19 and 1/3 innings. He's also coughed up 2.33 homers per nine innings. Struggles aren't a recent development for Harvey, either. In 387 innings pitched since 2017, he has a 6.35 ERA and 4.87 SIERA.

Harvey's been knocked around by lefties and righties alike this year. Left-handed batters have thumped him for a .338 wOBA. Righties have teed off on him for a .584 slugging percentage and .419 wOBA. His deficiencies retiring lefties and righties opens up all of the Houston Astros for stacking consideration.

My favorite four-person stack from the Astros in GPPs when factoring in my preferred pitcher and secondary stack features Yulieski Gurriel ($3,200), Yordan Alvarez ($4,100), Carlos Correa ($4,100), and Abraham Toro ($2,800). This four-person stack has explosive upside while providing lineup-spot correlation and even a pinch of salary relief with Gurriel and Toro.

Philadelphia Phillies

Jordan Holloway is officially getting the start for the Miami Marlins tonight. He spent most of the early season in Miami's bullpen, making 16 relief appearances and only two starts, lasting a total of 17 and 2/3 innings. He last pitched for the Marlins on May 21 in relief and has since made four starts in the minors. He reached 5 and 2/3 innings pitched in his most recent start, indicating he's stretched out to be utilized in a traditional starter capacity.

However, he's not good. According to Baseball-Reference, he has a 4.64 ERA in 320 and 1/3 innings pitched across all of his minor-league stops. That's hardly a promising number for his odds of success against big-league hitters.

Picking hitters to stack against, the simple and straightforward move of trotting out Odubel Herrera ($2,500), Jean Segura ($2,500), Bryce Harper ($3,900), and J.T. Realmuto ($2,900) from the top four spots in the lineup makes sense. With three of the hitters carrying salaries under $3,000, they're a superb stack to blend with the Astros while leaving enough salary for a top arm.
