3 Daily Fantasy Baseball Stacks for 9/21/17

The Twins are primed for a big night, but the Padres also make for a sneaky option. Who has the best shot at taking home top stacking honors tonight?

Stacking can be a controversial topic in many daily fantasy sports, but you can count baseball as a glaring exception. Here, it's universal.

Using multiple players on the same team on a given day presents you with the opportunity to double dip. If one of your players hits an RBI double, there's a good chance he drove in another one of your guys. When you get the points for both the run and the RBI, you'll be climbing the leaderboards fast.

Each day here on numberFire, we'll go through four offenses ripe for the stacking. They could have a great matchup, be in a great park, or just have a lot of quality sticks in the lineup, but these are the offenses primed for big days that you may want a piece of.

Premium members can use our new stacking feature to customize their stacks within their optimal lineups for the day, choosing the team you want to stack and how many players you want to include. You can also check out our hitting heat map, which provides an illustration of which offenses have the best combination of matchup and potency.

Now, let's get to the stacks.

Minnesota Twins

The Detroit Tigers must have some blackmail or something on Jordan Zimmermann. Poor dude has gotten blasted this year, and he is on track to start tonight despite a neck issue.

In 150 innings, Zimmermann has logged a 5.26 SIERA, 38.9% hard-hit rate, and 42.3% fly-ball rate, which also includes an 8.2% swinging-strike rate. Batters are making a lot of contact, and they are hitting it very, very hard. Poor Jordan.

Both sides of the plate are hitting the veteran right-hander well, but I give a slight nod to lefties, who have smacked him for a .384 wOBA and 1.82 home runs per nine innings, versus still-robust marks of a .375 wOBA and 1.66 home runs per nine.

Joe Mauer's monster 2009 season, where he rocked 28 homers, seems like a distant memory -- he only has seven on the year -- but he is still in a great spot tonight. He's pummeled righties for a .353 wOBA and a 40.9% hard-hit rate, and will run you $3,700.

To save some cash and roster Mauer, Kennys Vargas ($3,000) is an interesting option. He owns a 115 wRC+ and .223 ISO, and dude can crush regardless who is on the mound.

Lastly, check out the big German, Max Kepler, who is only $2,500. He is virtually worthless against lefties (wRC+ of 4), but he's been far better with the platoon advantage (wRC+ of 117). He's recorded a 36.1% hard-hit rate and 42.2% fly-ball rate in this situation in 2017.

San Diego Padres

I am not crazy, I swear. I think the San Diego Padres make for a really attractive stacking option, and let me tell you why.

Tyler Anderson takes the pill for the Colorado Rockies, and he has not had the greatest of 2017 seasons. In 73 1/3 innings pitched, he's recorded a 5.28 ERA, a 31.2% hard-hit rate, and 31.8% fly-ball rate, including a whopping 1.84 home runs per nine innings pitched.

One would think Anderson is hit hard as a Coors Field pitcher, but his numbers are actually worse away from Denver -- he has allowed a .344 wOBA and 3.76 xFIP in 34 1/3 home innings versus road marks of a .377 wOBA and 4.13 xFIP on the road in 39 innings of work.

All bats are in play against, but he's experienced most of his problems against righties, which is what we'll focus on.

Hunter Renfroe ($2,600) has been known to tag a lefty or two this season.

In 118 plate appearances against southpaws, Renfroe owns a 1.142 OPS, .379 ISO, and 179 wRC+. He needs to be a part of all Padres stacks. Priced slightly above him at $2,900, Manuel Margot has been manning the leadoff spot, and he could wreak havoc tonight against Anderson with a season-long mark of a .356 wOBA, 10.2% walk rate, and 133 wRC+ against lefties.

Last but not least, Jabari Blash ($2,400) may have the most attractive batted-ball profile of the bunch, recording a 46.3% hard-hit rate and 41.5% fly-ball rate with the platoon advantage in 2017.

Toronto Blue Jays

Jason Vargas is in a situation similar to Zimmermann, and he keeps taking the ball for the Royals despite some really poor marks. In the 57 second-half innings, Vargas has posted a 7.11 ERA, .396 wOBA, 39.9% hard-hit rate, and 36.8% fly-ball rate allowed.

And the numbers are even worse over the last nine starts. Against right-handed batters, Vargas has allowed 2.5 home runs per nine innings pitched, a .600 slugging percentage, and a 41.0% hard-hit rate allowed during that time.

If a Toronto Blue Jays stack is in the cards, Josh Donaldson must be rostered.

At $4,100, Donaldson has been absurd in the Rogers Centre, and it's even more bananas with a lefty on the bump. In this situation this season, the third baseman is rocking a 137 wRC+, .406 ISO, 45.5% hard-hit rate, and 54.5% fly-ball rate.

To roster Donaldson, there are two cheap right-handed options we can explore, and the first is the switch-hitting Kendrys Morales, who is far cheaper at the other corner spot at $3,200. As a righty, Morales has bopped his way to a 158 wRC+ and 43.5% hard-hit rate.

Finally, Kevin Pillar who is priced well at $2,900, should not be ignored. In this situation, he's put up a .396 wOBA, .230 ISO, 30.2% hard-hit rate and 38.3% fly-ball rate.
