Los Angeles Dodgers

In 86.1 innings this season, Colorado Rockies right-handed rookie Peter Lambert has really struggled as he's sporting a 5.53 SIERA, which is the third-worst mark on the slate. His walk rate of 8.7 percent and strikeout rate of 13.4 percent are both poor and should never be within five percentage points of each other. Lambert has allowed a 38.7 percent hate-hit rate and nightmarish 25.0 percent line drive rate -- the worst mark on the slate.

There are a trio of hitters -- two lefties and a righty -- who stand out as elite options against right-handed pitching when it comes to the Los Angeles Dodgers. Cody Bellinger ($4,500) has been playing at an MVP-caliber level this season and has done so much damage against righties with a .426 wOBA and .331 ISO in the split. Bellinger is also a Statcast darling with his 8.9 percent barrels per plate appearance, 90.6 MPH average exit velocity and 206-foot average batted-ball distance against lefties and righties combined.

Fellow lefty Joc Pederson ($3,200) has similarly elite numbers against righties with a .370 wOBA and .305 ISO in the split. Pederson is always a pinch-hit risk later in games, but that should not deter you from using him tonight. Catcher Will Smith ($2,600) is way too cheap considering his dominance against righties this season. He's put up a .382 wOBA and Dodgers-best .367 ISO against righties and should be in the lineup tonight.

Another pair of lefties who should be in consideration are Matt Beaty ($2,700), who is sporting a .364 wOBA and .232 ISO against righties, along with Max Muncy ($3,500) and his .364 wOBA and .259 ISO in the split. A couple others worth considering are Corey Seager ($3,400) and A.J. Pollock ($4,000).

New York Yankees

The Toronto Blue Jays' rookie right-hander Jacob Waguespack hasn't been that good this season. He's giving up a 40.0 percent hard-hit rate and 22.4 percent line-drive rate while walking 8.9 percent of the batters he faces and striking out just 17.8 percent of them. Tonight he's got a tough matchup against a New York Yankees team that has way too much power.

Left-handed veteran Brett Gardner ($2,900) has to be considered when you see his .377 wOBA and ridiculous .291 ISO against righties. Following Gardner, you're going to want to focus your attention to two right-handed hitters who have had plenty of success against righties. Giovanny Urshela ($2,900) has an elite .385 wOBA and modest .213 ISO against righties whereas Gleyber Torres ($4,100) has a .366 wOBA and very good .267 ISO in the split.

Next I want to talk about the two bash brothers who crushed righties in 2018 but not so much in 2019. Aaron Judge ($4,700) has struggled against righties whereas Giancarlo Stanton ($3,900) has missed the majority of the season with injuries. In 2018, Judge hit righties to the tune of a .384 wOBA and .238 ISO, and Stanton put up a .337 wOBA and .215 ISO in the same split. Now, neither of those stand out considerably, but they are two of the best power hitters in the game and are absolutely in play tonight.

Finally, definitely consider Yankees lead-off man DJ LeMahieu ($3,900) and first-baseman Luke Voit ($3,200).

Washington Nationals

We seem to be focusing on a lot of rookie pitchers tonight, and this matchup is no different as the Washington Nationals visit Miami to take on the Marlins. They'll face Miami Marlins rookie Robert Dugger, who has just 27.1 innings under his belt in the Majors. With that said, take the following stats with a grain of salt due to sample size. He has a 10.7 percent walk rate, 14.8 percent strikeout rate, 45.4 percent hard-hit rate, 23.5 percent line drive rate and a 5.88 SIERA. All are pretty terrible, but the sample size is so small that you don't want to read too much in to them. For a larger sample, we can look to his very meh 19.9% strikeout rate this season across 53 1/3 Triple-A innings.

Let's focus on the Nationals who are very good against right-handed pitchers. Two hitters who stand out the most are Anthony Rendon ($4,200) and Juan Soto ($4,100). Rendon has been a machine in a season in which he signed a one-year deal and bet on himself. He's put up a ridiculous .421 wOBA and .285 ISO against righties, and Soto, in his second Major League season, has managed a .420 wOBA and a .315 ISO in the split. Rendon also smashes with a 9.3 percent barrels per plate appearance and an incredible 210-foot average batted-ball distance against lefties and righties combined.

We now turn to two speedsters in Trea Turner ($4,300) and Victor Robles ($3,000), both of whom have stolen more than 25 bases this season. Their power certainly leaves a lot to be desired, though, as Turner has a .349 wOBA and a .192 ISO against righties while Robles is sporting just a .319 wOBA and .181 ISO in the same split.

A few other hitters to consider are Adam Eaton ($3,100), Asdrubal Cabrera ($2,900) and Howie Kendrick ($2,800)/Ryan Zimmerman ($2,700), depending which first basement ends up in the lineup.

Houston Astros

It feels like every day we get either the Minnesota Twins or Houston Astros in this piece. Tonight, both of them are elite plays, but let's spend a bit of time on the Astros.

In 75 innings this season Jaime Barria has not been great. He's giving up a 40.8 percent hard-hit rate and 45.0 percent fly-ball rate, which has resulted in a 17.5 percent home-run-to-fly-ball rate. He looks pretty bad according to his Statcast numbers as he's allowing a 7.3 percent barrels per plate appearance, 89.1 MPH average exit velocity and 204-foot average batted-ball distance.

As always, we start with the beast Yordan Alvarez ($4,200). The kid mashes, and the Statcast data backs it up. He has an 11.0 percent barrels per plate appearance, 92.6 MPH average exit velocity and 203-foot average batted-ball distance against lefties and righties combined. Of course, he also smashes righties outright with a .448 wOBA and .364 ISO -- both of which lead the Astros in the split.

Two other righties who are dominant in righty-righty matchups are George Springer ($4,100) and Alex Bregman ($4,000). Springer has managed a .405 wOBA and .316 ISO against righties while Bregman has a .401 wOBA and .260 ISO in the split.

Also in play for Houston are Michael Brantley ($3,800), Yulieski Gurriel ($3,600), Jose Altuve ($4,400) and Carlos Correa ($3,600) -- all of whom have varying levels of success against righties.
