3 Daily Fantasy Baseball Stacks for Tuesday 5/25/21

The Washington Nationals are hot of late and a top stacking option tonight, but which pair of California clubs join them?

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.

Washington Nationals

The Washington Nationals rank tied for 16th in weighted runs created plus (95 wRC+) against right-handed pitchers for the season, per FanGraphs. Opposing starter Tyler Mahle has been a rock-solid pitcher, too. It seems like a less-than-ideal offense to stack.

However, there's a confluence of recent happenings that leads me to believe this could be a sneaky-good stack tonight. First, the Nationals are starting to hit of late. They rank ninth with a 117 wRC+ over the last 14 days. Second, Mahle's suffered a couple of hiccups of late, getting rocked for six runs in five innings on May 2 and getting torched for seven runs in only two innings in his last start.

Leadoff hitter Trea Turner ($3,900) is an integral piece of high-upside exposure to this stack. Wunderkind teammate Juan Soto ($4,000) is too. The two other hitters I prefer to include in a full-stack are Josh Bell ($3,200) and Kyle Schwarber ($3,700). The two offseason additions have been raking of late, recording a .200 isolated power (ISO) and 143 wRC+, and a .347 ISO and 190 wRC+ over the last 14 days, respectively.

San Francisco Giants

The Arizona Diamondbacks turn to Corbin Martin tonight. It's a plus matchup for the San Francisco Giants.

Martin is a youngster with some prospect fanfare, but it's yet to click in his limited big-league time. In six starts lasting only 24 and 1/3 innings, he's been hit around for a 5.55 ERA, 5.39 skill-interactive ERA (SIERA), 1.77 WHIP, and 3.70 homers per nine innings allowed. The righty's home ballpark is unlikely to do him any favors in figuring things out at the game's highest level. According to FantasyPros, Chase Field has the eighth-highest park factor for runs (1.040).

My stacking focus is on the top-four hitters in San Francisco's lineup. Mike Yastrzemski ($3,100) has recently been elevated to the leadoff spot against righties, and he's hammered them for a .313 ISO and 147 RC+ this year. Buster Posey ($3,800) is hitting second, and he's turned the clock back this season, raking against righties for a .400 on-base percentage, .243 ISO, and 164 wRC+.

White-hot Brandon Crawford's ($3,000) been bumped up to the third spot in the order, and he's creaming righties this year for a .398 on-base percentage, .301 ISO, and 172 wRC+. Brandon Belt ($2,800) rounds out my favorite streaming option from the Giants, muscling up for a .301 ISO and 141 wRC+ with the platoon advantage this season.

Oakland Athletics

Martin's not the only prospect hurler who's failed to make the transition from the minors to the majors a seamless one getting the ball tonight. Logan Gilbert has made two starts for the Seattle Mariners in plus matchups, and he's coughed up seven runs on nine hits, two homers, and two walks in 6 and 2/3 innings. Tonight's matchup is a step up in competition, so it's possible things could get worse for him before they get better.

The Oakland Athletics rank 11th in wRC+ (102) and fourth in ISO (.183) against right-handed pitchers this season. Their power output is especially noteworthy given Gilbert's fly-ball tendencies. He's induced a grounder on a tiny 13 percent of balls put in play against him, ceding a 34.8 percent line-drive rate and a 52.2 fly-ball percentage. Oakland's power should be present tonight.

When discussing power and the A's, it's imperative to mention Matt Olson ($3,600). He has a .264 ISO against righties since 2018, and he's responsible for a .280 ISO against them this year.

Ramon Laureano ($3,700) and Seth Brown ($2,500) are a couple more hitters I'm locked in on from this lineup, though it's a lineup with stacking options beyond my favorites. Laureano has a .217 ISO against righties since 2018 and a .243 ISO against them this year. Brown's ripped off a .243 ISO against righties since debuting for the A's in 2019 and a .293 ISO this year.
