4 Daily Fantasy Baseball Stacks for 5/21/19

We jump up to 14 games on Tuesday's main slate, though a lot of the same teams as yesterday are back on the stacking radar. Will teams like the New York Yankees and Texas Rangers feast again tonight?

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 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

Most of the Houston Astros disappointed against the Chicago White Sox last night, but we shouldn't hesitate to go right back to them, as they draw one of the best matchups of the night versus Dylan Covey.

Covey has performed poorly since debuting in 2017, posting a 5.64 SIERA over 70.0 innings that season, followed by a 4.59 mark across 121.2 innings in 2018. His career strikeout rate sits at 14.9%, alongside a similarly lackluster 10.6% walk rate.

Early returns in 2019 suggest more of the same, with an ugly 7.49 SIERA, 8.1% strikeout rate, and 16.2% walk rate through 16.2 innings. Even his normally high ground-ball rate hasn't materialized yet this year (32.7%). A minuscule .170 BABIP is likely the only reason his ERA isn't higher than 4.41.

Houston's active roster leads the league with a robust 130 wRC+ against right-handed pitching, and they should smash in a matchup this soft. In addition to the usual suspects like Alex Bregman ($4,300) and Carlos Correa ($4,100), we can once again dip lower in the order for cheaper bats like Yulieski Gurriel ($2,700), Tyler White ($2,400), Robinson Chirinos ($3,000), or Jake Marisnick ($2,200).

White has basically been in a slump all season but finally got on the board with his first home run last night. His 48.1% hard-hit rate in the month of May gives hope that he'll start performing more like the guy with a career .193 ISO.

If George Springer ($4,500) is out again, Josh Reddick ($3,100) could check in as a cheap leadoff man again, too.
