After some hefty slates to start the week, we're dropping down to just five games on Wednesday's main slate, but the New York Yankees and Boston Red Sox are some familiar names leading the way in implied team totals tonight. However, be sure to keep an eye on the forecast in Baltimore and Boston, as potential rain could also factor into your decision-making. Also note that the slate locks at 6:40pm ET, so you'll need to get those lineups in a little earlier than usual.

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.

Boston Red Sox

With a massive 6.95 implied total that's only gotten higher throughout the day, if the weather cooperates, there's little question that the Boston Red Sox will be immensely popular on such a short slate.

The high implied total comes with good reason, though. Glenn Sparkman has poor numbers all around, entering the contest with a 5.47 SIERA and 13.0% strikeout rate while allowing 2.03 homers per nine innings off a 41.0% hard-hit rate and 37.4% fly-ball rate. As you might expect from those batted-ball marks, he also fails miserably on the Statcast front, ranking in the 8th percentile or worse in all of xwOBA, xSLG, and xBA.

The Royals' bullpen only further adds appeal to the matchup, coming in with a bottom-six xFIP among active rosters.

Mookie Betts ($4,300), J.D. Martinez ($4,300), and Xander Bogaerts ($4,100) are among the top plays as usual, and as noted in today's daily helper, Sparkman particularly struggles against lefties, giving rising star Rafael Devers ($4,400) a fantastic boost. That could also mean good things for Andrew Benintendi ($3,900), Brock Holt ($2,300), Mitch Moreland ($3,200), and Jackie Bradley ($2,600).

Christian Vazquez ($2,800) continues to be a bright spot for the Sox, as well, with a career-high .207 ISO in 2019.
