Top MLB DFS building blocks for Monday

The Astros are likely to put runs on the board this evening, but which of their stars is a must-pick for your DFS lineups? Joe Nicholson-USA TODAY Sports

Our experts are here to provide the best hitters and pitchers for you to build your daily fantasy baseball lineups around on Monday.

Hitters to build around

Eric Karabell -- Garrett Cooper, New York Yankees

Acquired just before the weekend, Cooper was 1-for-10 at Fenway Park, but don't judge him harshly. He's a right-handed hitter with pop and plate discipline. The Brewers weren't going to promote him from Triple-A but the Yankees have a real need and Cooper should produce -- at least against left-handed pitching, and Monday he'll face in Minnesota's Adalberto Mejia. Cooper's lack of weekend production means nothing. His OPS was better than 1.000 in Triple-A and it wasn't a fluke.

Joe Kaiser -- George Springer, Houston Astros

How many home runs do you think Springer has off of Mariners lefty Ariel Miranda? The Astros' slugger has taken the Seattle southpaw deep four times in only 15 plate appearances. Springer is also batting .345 with nine homers and a 1.137 OPS vs. LHP on the season, so even if you don't buy the small sample above, you can see he's great against southpaws. Get him in your lineups on Monday.

Kyle Soppe -- Milwaukee Brewers lefties

The Brewers' infield is loaded with left-handed (or switch) hitters and I want them. All of them. Yep, that means I'm rolling with Stephen Vogt, Eric Thames, Jonathan Villar, and Travis Shaw against Chad Kuhl, a pitcher who owns the 12th-highest wOBA against LHB of the 165 qualified pitchers since the beginning of last season. His career 41 percent fly ball rate against lefties is a major concern, as Vogt has an OPS of 1.064 since joining the Brewers and both Thames and Shaw have an OPS north of 1.000 in July. Villar has hit seven of his eight homers and stolen 16 of his 18 bases against RHP this season, making him a switch hitter to target in this spot.

Pitchers to build around

Eric Karabell -- Brent Suter, Brewers

The 27-year-old left-hander will come cheap but he's pitched well of late, registering quality starts against the Yankees and Orioles and striking out 13 over 12 1/3 innings. Suter is a swingman and not long for the rotation but Monday he'll face the Pirates in their place, and the Pirates are hitting .232 with only 20 home runs all season against lefties. Suter should be able to provide six reasonable innings and allow DFS owners to afford Lance McCullers Jr. and plenty of big bats.

Joe Kaiser -- Lance McCullers Jr., Astros

In two outings against the Mariners this season, McCullers has limited Seattle bats to nine hits and two runs in 11 innings while striking out 15. He's been great at home all season and has the support of a terrific offense behind him in a game where the Astros have a chance to score a lot of runs. The Mariners are coming off a three-game sweep of the White Sox, but simply haven't been able to figure out the Astros the past three seasons. Take advantage of that tonight.

Kyle Soppe -- German Marquez, Colorado Rockies

Marquez has done anything but struggle over his last four home starts (2.02 ERA) despite facing offenses (White Sox, Diamondbacks, Cardinals, and Cubs) that rank significantly ahead of tonight's opponent in the Padres. How bad has San Diego been? Against righties this season, they rank dead last in hard contact percentage, 29th in wOBA, and first in strikeout percentage. He needs to be locked into your FanDuel lineup and is viable in DraftKings as well.
