4 Daily Fantasy Baseball Stacks for 5/20/16

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. Here are the teams you should be targeting in daily fantasy baseball today.

Washington Nationals

It's always a red flag when a pitcher has more walks than he has strikeouts. But when that guy has more than twice as many walks as strikeouts through four starts? That should bring the Knowshon Moreno tears of happiness. That's what the Washington Nationals get when they face Justin Nicolino.

Nicolino's four starts have seen him face 101 total batters, and he has struck out 4 while walking 11. It's borderline impressive to have only a 4.0% strikeout rate when the sample size is that large. His ERA is 3.75, but a 6.55 SIERA will tell you a radically different story, and the Nationals are more than capable of making him pay.

Despite the platoon disadvantage, Bryce Harper still pummels lefties. Don't worry about him. We just need a second to gush about Ryan Zimmerman. Zimmerman has 128 plate appearances against lefties since the start of 2015, and he has spanked them with a 49.5% hard-hit rate. His 29.2% fly-ball rate over that span isn't quite as awe-inspiring, but he's going to have a boatload of dudes on base each time he comes to the dish. Jayson Werth and Anthony Rendon are also lefty killers, so you won't have a shortage of quality choices in formulating a Nationals stack today.
