4 Daily Fantasy Baseball Stacks for 4/20/15

Several left-handers starting on the mound tonight create for plus matchups you can exploit.

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.

Detroit Tigers

The Tigers have been a good stacking option pretty much the entire year with how sickly their offense has been. Today, though, they face CC Sabathia, which means a whole lot of tasty split numbers against left-handers.

This only spans 121 plate appearances, but the Tigers lead the league in wOBA against left-handed pitching this year at .382. The next-highest team on those rankings is the Royals at .362. Grossness to the max.

If you can fit his salary in, Victor Martinez would be a great guy to roster from this one. Even though he murked most pitching last year, this was especially true when he was batting right-handed. There, he posted a .371/.430/.692 slash with a .476 wOBA. He's obviously not the only Tiger that sees the sizable spike, but he's one you'll want to find room for today.

Los Angeles Angels

The last time I mentioned stacking against Kendall Graveman, he proceeded to contribute 5.1 innings to a shutout of the Houston Astros. Whoops! For some reason, I don't see that happening against the Los Angeles Angels.

The Angels haven't exactly come out of the gate the best, posting a .271 on-base and a .348 slugging percentage against right-handers. That's partially due to a low .253 BABIP against those righties, which is unsustainably low when you factor in their 21.0 line-drive percentage. Those numbers will bounce back up soon.

Another component of this stack is the weather. We seem to have gone back into cold-weather mode again as this is the only game on the schedule where the projected first-pitch temperature is at least 60 degrees. Detroit's projected 57 degree mark is second followed by the weather in Seattle at 53. Even Los Angeles's 60 degree forecast isn't great, but it's a better option than a bunch of other places on today's slate.

Seattle Mariners

Speaking of Seattle, they've got themselves a pretty tasty match-up today as well. Asher Wojciechowski isn't a high strikeout guy, he has allowed a pair of bombs through his first eight innings this year, and has has only induced ground balls 22.2 percent of the time. Count me in.

As with Los Angeles, the BABIP gods have not yet smiled on the Mariners this year. They have a .270 BABIP against right-handers this year, but have still managed to post the 12th-highest wOBA against them. No team has posted a higher fly-ball percentage against righties this year with their 43.9 mark topping the Minnesota Twins in second at 41.8.

Despite playing his home games in Petco last year, Seth Smith still managed to produce at a .270/.359/.455 slash against right-handers last year. His fly-ball percentage in that situation also increased to 32.3 percent. He, like many Mariners, would be a mighty fine play tonight against Graveman if he's in the lineup.

Cleveland Indians

This is a matchup we just saw last Wednesday, when John Danks allowed four runs in 4.2 innings of work. The bullpen came in and only allowed two hits over 3.1 innings, but any team is stackable with Danks on the mound.

One guy who has been kind of an interesting surprise this year is Roberto Perez. He posted a .261/.280/.522 slash last year in triple-A in 209 plate appearances. With Yan Gomes out, Perez has blasted a pair of home runs in his 26 plate appearances for a .261/.280/.522 slash. Perez hits low in the order, so he might not be the best play in cash games, but if you're in a tourney, he's a useful and cheap part of this stack.

The other guys who have had positive lefty splits recently have been Carlos Santana and Jerry Sands. Assuming they're in the lineup, you'll want them in yours for today's game. The risk with Sands is that he could be pinch-hit for if Danks leaves the game early. Even with that, I'm still willing to bump with him in tourneys because there be some dong potential in that bat.
