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. As always, we will not be using today's game at Coors Field here. Coors Field is obviously fantastic for DFS, but you likely don't need me to tell you that. Here are the other teams you should be targeting in daily fantasy baseball today.

Houston Astros

It would seem safe to say that this has been a weird season for the Houston Astros. Despite not losing any big-time assets on offense, they are still just 13th in the league in wRC+ overall, a step back from their 4th-place ranking last year. With all of the young talent they've got, you'd expect that to trend the opposite direction. Still, even with the struggles, it's hard to pass them up when they face a low-strikeout hurler like Kendall Graveman.

Graveman's strikeout rate for the year has dipped to 14.8%, dragging his SIERA with it as that is now up at a career-high 4.69. He was showing improvements earlier in the year, but those evaporated at the start of June as he has an 11.4% strikeout rate in seven starts since. Add in his 12.0% strikeout rate against right-handed batters, and you can see why we'd be interested in the Astros given all of their big-bopping righties.

A major cog in the Astros' lack of development is the perceived struggles of Carlos Correa. His wOBA has fallen to .352 from .365 last year, and while that's obviously good, it's not the superstar-esque mark you'd expect out of a guy like Correa.

That's going to change soon.

Ever since an injury kept him out of the lineup for a few days in mid-June, Correa has a 40.5% hard-hit rate, up from his mark of 32.9% last year. It's not that he's not improving; that's absolutely happening. It's just that the results haven't followed yet, but we should be snagging him in DFS while the pricing is still low.
