4 Daily Fantasy Baseball Stacks for 4/30/15

The Houston Astros have the hottest offense in the Majors right now, and they could be in line for another big night tonight.

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

Houston Astros

Which team has the hottest offense in the Majors right now? It might be the team that went to Petco Park, which has one of the worst park factors in the league, and scored at least seven runs in all three games. This was a series after they scored at least five runs in each game in a three game series with Oakland. This is a team averaging 8.5 runs per game over their last six. That would be the Houston Astros.

Lefty James Paxton presents the Astros' biggest mashers with a positive platoon advantage. Paxton isn't a heavy fly-ball pitcher, but their mashing abilities should help make up for that.

I don't care what kind of slump he's in; Evan Gattis is dirty to the max against left-handers. Last year, he hit .343/.356/.614 against them with a .419 wOBA. Same goes for Chris Carter, who last year posted a .519 slugging percentage off of south paws. Those two will only cost you $3,900 and $4,400 on DraftKings today respectively which makes this stack a no-brainer.

Seattle Mariners

It's not the only game with an over/under above eight for no reason! A stack including plenty of ownership in both the Mariners and the Astros could end up with some pretty sweet returns.

Each of the past two days, numberFire's projections have been super high on Kyle Seager, and that was when the Mariners were facing a pair of lefties. Now, you give him the platoon advantage, and they could be slobbering all over the place. Assuming that Seager's thumb injury is nothing too serious and he's back in the lineup, he's an absolute steal at $3,900 in the late slate on DraftKings.

The other positive with stacking the Mariners is their use of platoons. Whether it's Justin Ruggiano or, most likely in this case Seth Smith, in the lineup, they're often hitting second. You get the double benefit of top-of-the-order opportunities with replacement player salaries. This can also help you afford the higher-priced guys on the team (waddup, Nelson Cruz?) who might not fit in other situations.

Toronto Blue Jays

If you exclude Tuesday's 11-run explosion, the Toronto Blue Jays are averaging 2.4 runs per game over their past five. There is no better cure for that than a visit from T.J. House.

Through his first three starts (which have lasted a grand total of 10 innings), House has a 12.60 ERA, a 6.34 FIP and a 5.70 xFIP. These numbers are a slight amount less than optimal. You match him up with the Blue Jays, and you get straight fireworks.

I know he's going to cost you a lot ($5,300 on the late slate on DraftKings), but Jose Bautista is almost guaranteed to dong tonight. In 2014, he slashed .345/.449/.629 against lefties. He gets medieval on their unsuspecting behinds. He may do the same to your chances of cashing if you fade him tonight.

Detroit Tigers

Overall, Danny Duffy has been a'ight this year. But he hasn't faced a team that can bop 'em like the Tigers yet.

Duffy's four starts have been against the Twins, Athletics and two against the White Sox. Those teams entered play yesterday ranked 24th, 28th and 29th respectively in wOBA against left-handed pitching. The Tigers, conversely, rank fifth as they have accumulated a .351 wOBA with a .277/.361/.435 split against lefties. That changes things for good ol' Mr. Duffy.

This presents an interesting situation when it comes to Victor Martinez. His bum knee is his left one, which would cause him more trouble when he's batting left-handed (and pushing off with that leg) as opposed to when he's in the right-handed batter's box. This has shown up in his early season splits. While he's slashing .171/.308/.171 against righties, that leaps to .400/.500/.467 against lefties. He's not hitting for much power either way, but he's certainly more in play in situations like this.
