4 Daily Fantasy Baseball Stacks for 8/18/17

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.

As always, the Coors Field game will be ignored for stacking purposes.

Now, let's get to the stacks.

Baltimore Orioles

Despite saying Andrew Heaney would not pitch in 2017 as he recovered from injury, the young lefty makes his season debut tonight for the Los Angeles Angels at Camden Yards, which could be a real problem.

Coming of Tommy John surgery, the southpaw gets to face a Baltimore Orioles team that ranks third in wOBA (.367) over the last 14 days. They also lead the league in ISO (.238) during this time off the strength of 25 homers.

The top of this stack is where we want to start, and that trade with the Tampa Bay Rays is looking pretty darn good right now.

Traded for a minor leaguer, Tim Beckham has been absurd since coming to Baltimore -- he's posted a 243 wRC+, 36.2% hard-hit rate, and 42.6% fly-ball rate over the last two weeks.

Trying to keep pace with Beckham, but a hair more costly, Manny Machado has been equally ridiculous during the same amount of time, rocking a 174 wRC+ with 5 homers and 19 RBI.

Lastly, don't sleep on Welington Castillo at the hard-to-fill catcher slot. He's posted a .949 OPS at home against lefties this year, and as a part of this white-hot offense, has a 1.030 OPS in the last 14 days.
