3 Daily Fantasy Baseball Stacks for Tuesday 6/8/21

The righty-heavy Phillies have a favorable matchup against lefty Drew Smyly tonight. They're not the only righty-leaning lineup in plus draw against a southpaw that's worth stacking.

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.

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

Philadelphia Phillies

Among tonight's probable starters, Drew Smyly has the second-highest ERA (5.98) and homers per nine innings allowed (2.70 HR/9), and the 10th-highest skill-interactive ERA (4.47 SIERA). The southpaw has also fared poorly against hitters with the platoon advantage, allowing a .481 slugging percentage and .340 weighted on-base average (wOBA) to righties this year, per FanGraphs.

Circling back to his homer woes, playing at Citizen Bank Park will do him no favors tonight. According to the park factors at FantasyPros, Citizens Bank Park has the third-highest park factor for homers (1.202).

All of the Philadelphia Phillies in the projected top-seven spots in the order are viable considerations for stacking. Whittling things down to my favorites leaves Jean Segura ($3,300), Andrew McCutchen ($3,500), and Rhys Hoskins ($3,300). Segura has a 123 weighted runs created plus (wRC+) against lefties since 2018, an identical mark against them this year, and a 117 wRC+ over the last 30 days.

Cutch has been even better, recording a .220 isolated power (ISO) and 140 wRC+ since 2018, a .329 ISO and 174 wRC+ this year, and a .271 ISO and 137 wRC+ over the last 30 days. Hoskins has been the most accomplished hitter under each of those conditions, ripping a .238 ISO and 145 wRC+ against southpaws since 2018, a .288 ISO and 180 wRC+ against them this year, and a .191 ISO and 146 wRC+ over the last 30 days.

Houston Astros

There is a chance a Houston Astros stack might be somewhat contrarian if recency bias pervades the daily fantasy baseball community. Opposing starter Martin Perez held them scoreless through 7 and 2/3 innings pitched in his most recent start. So what? Sure, the Astros would be more appealing on the heels of drilling him. However, gamers would be more inclined to chase points.

Taking a broader view supports stacking the Astros tonight. They rank second in wRC+ (125) against lefties this year and first in wRC+ (127) over the last 30 days. They also have five projected starters -- Jose Altuve ($4,100), Carlos Correa ($3,400), Yulieski Gurriel ($3,100), Yordan Alvarez ($3,200), and Alex Bregman ($3,100) -- with a 133 wRC+ or higher against lefties since 2018.

Playing at Fenway Park is also a significant factor supporting stacking the Astros. It has the third-highest park factor for runs (1.103) and the highest mark for doubles (1.404). This is a stackable offense from top to bottom. Further, even if you're not fully stacking it, I advise mixing in a player or two from Houston's lineup with your other stack -- or stacks.

San Francisco Giants

Jordan Lyles is so bad. I believe even the injury-riddled lineup of the San Francisco Giants can rough him up. Additionally, they can do so as a salary cap-friendly stack, providing valuable savings for spending up for an ace -- should you choose to build your roster around one. Among tonight's starters, Lyles has the fifth-highest ERA (5.75), ninth-highest homers per nine innings allowed (1.62 HR/9), and eighth-highest SIERA (4.55). Moreover, the veteran righty has been inept against lefties and righties alike, coughing up a .323 wOBA to the former and a .391 wOBA to the latter.

Revisiting the valuable salary-cap space stacking the Giants will provide, Buster Posey ($3,200) has the highest salary on the team, followed by Brandon Crawford ($3,000). Everyone else has a salary below $2,500.

In addition to providing the means to use an ace, they also make for an appealing stack to blend with a high-priced stack and said ace. This stack makes the cut for what they allow you to do with the rest of your roster as much as because of its own upside.
