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.

Houston Astros

Facing Miguel Gonzalez of the Chicago White Sox, the 'Stros are once again in play, but there are some different bats to highlight for this Houston stack.

Gonzalez has racked up a 5-10 record and a 5.15 ERA this season, and a 5.56 SIERA would indicate his poor performance hasn't had much bad luck involved. Gonzalez has really struggled with left-handed batters, allowing a .365 wOBA, 35.5% hard-hit rate, and 39.6% fly-ball rate this year. And when it comes to the Houston Astros, they can roll out plenty of hitters from that side of the plate.

That's not good for Miguel because Marwin Gonzalez has turned into Babe Ruth as a left-handed hitter.

Gonzalez has recorded 251 plate appearances as a lefty, and he's logged a .338 average with a 1.022 OPS, and 36.1% hard-hit rate. He should be the focal point of this stack.

Derek Fisher ($3,000), Josh Reddick ($3,700), and Carlos Beltran ($3,100) also give you lefty exposure to the White Sox hurler at affordable price points.
