4 Daily Fantasy Baseball Stacks for 8/20/15

Each day here on numberFire, we'll be providing you with four potential offenses to stack in your daily fantasy lineups. These are the offenses that provide huge run potential on that given day based on matchups and other factors.

After reading through these suggestions, make sure to check out our daily projections. These can either let you know which players to include in each stack, or which guy best complements said stack.

Another great tool is our custom optimal lineups, which are available for premium subscribers. Within the tool, we've added the option to stack teams -- you choose the team you want to stack, show how many players you want to use within the stack, and the tool will create a lineup based on this that you can then customize.

Now, let's get to the stacks. As always, the Coors game between the Nationals and Rockies is not on this list. Yohan Flande has allowed similar splits to both lefties and righties, so most Nats bats should be in play. Here are the other teams you should be targeting in daily fantasy baseball today.

Texas Rangers

Normally, I'd knock the Rangers down a few rungs as they're playing on the road. Their wRC+ against right-handed pitchers is exactly average at 100, so it's not as if they're an overly-dominant park-neutral team. However, they get themselves Alfredo Simon tonight, and that, my friends, is too delectable to pass up.

Simon was able to survive in the rotation with the Reds last year because of a slightly above-average ground-ball rate. Now, 22 starts into his Tigers tenure, that ground-ball rate has sunk, his walks are up, and he presents exactly the upside we are looking for in a stack.

Simon's xFIP this year is similar against batters of either handedness at 4.61 versus lefties and 4.33 against righties. Right-handed batters strike out more, but they also hit more fly balls, so I'll be gravitating towards Adrian Beltre and Delino DeShields Jr. in tourneys. Lefties bring the higher floor, leaving you plenty of options from which to choose in the Rangers order.

Boston Red Sox

Considering how Adam Morgan pitched last night, this seems like a trap. The struggling lefty in Danny Duffy taking on a team that is crushing lefties in the Boston Red Sox. Let's just cross our fingers and pray the Red Sox fare better than the Blue Jays did against Morgan.

Duffy enters his 19th start of the season with a 5.06 SIERA. He has been a bit of a stumper in stacks, though, as he holds a 2.85 ERA in 10 starts since coming off of the disabled list in June. That 2.85 ERA is coupled with a 5.11 xFIP, so it hints that he should be regressing hardcore, yet it hasn't happened. I'm going to assume he's not whipping out some funky voodoo to magically exceed his xFIP and SIERA and roll with the Red Sox regardless.

Early in the season, the Red Sox were firmly planted in the lower tier of the league in wOBA against left-handed pitchers. With their recent rejuvenation, they're all the way up to fourth with a .331 wOBA and 106 wRC+. Additionally, the team has showed up better at Fenway than on the road. As long as he's not hitting ninth, I'll be bumping with some Jackie Bradley shares, not because of his crazy hot hand, but because of his 33.6 percent hard-hit rate and 37.5 fly-ball percentage in his career against left-handed pitching.

Baltimore Orioles

The sum of the xFIP's of the two starting pitchers in this game is 9.42. You'll want to snag yourself some ownership, especially in the O's as they face Tyler Duffey in his third career start.

Duffey caught himself a pretty tough break as he made his debut against the Jays. It went pretty much how you'd expect. He then came back last Saturday and took a no hitter into the sixth against the Cleveland Indians. Unfortunately, that came with five walks. He hasn't been bad overall in the minors, but this game carries some serious blow-up potential.

Despite a high strikeout percentage, Baltimore enters this contest eighth in the league in wOBA against right-handed pitchers. The O's make for a sweet tourney stack as they've got four guys (Manny Machado, Chris Davis, Adam Jones and Jonathan Schoop) who have isolated slugging marks higher than .200. Pick your pleasure, hold your breath, and see which version of Duffey shows up at Camden Yards.

Chicago Cubs

Tonight is just a good night for stacking. I'd also give some thought to loading up on Tigers and Yankees bats, but the Cubs against Mike Foltynewicz to me takes the cake for this fourth slot.

Over his first 77 innings with the Braves, Foltynewicz holds a 4.27 SIERA. While that's not ideal for his purposes, it's lower than a bunch of the other guys on the slate tonight. I want to target him because of the upside he presents in his low ground-ball rate. That could lead to a healthy number of dongs with the way the Cubs are swinging right now.

I'm going to assume that -- eventually -- Chris Coghlan's price is going to go up. Until that time, you should be targeting him with regularity against right-handed pitchers. He holds a .263/.346/.467 slash with a 32.5 percent hard-hit rate, all of which is great in tourneys. When he's batting third in an order like this one while only priced at $3,000 on FanDuel and $3,400 on DraftKings, it's pretty much a no-brainer.
