Top MLB DFS building blocks for Friday

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

Hitters to build around

Eric Karabell: Eric Sogard, Milwaukee Brewers

Sogard's impressive on-base skills are translating to consistent points in DFS and his salary remains low enough that he fits every budget, especially on a night with Max Scherzer and other high-end pitching. Sogard faces a Padres hurler in Miguel Diaz who has been mainly a relief pitcher, and one with control issues to boot. Expect several trips to first base and runs scored as well.

Tristan H. Cockcroft: Matt Carpenter, St. Louis Cardinals

He's still far, far, far too cheap considering his natural skills, and he's drawing one of the more under-the-radar-outstanding matchups, facing struggling Baltimore Orioles righty Kevin Gausman. Carpenter has averaged 13.8 DraftKings and 18.3 FanDuel points in his past nine games alone, he's slashing .266/.384/.521 for the season against righties, and he continues to see a maximum number of trips to the plate since his installation as the Cardinals' leadoff hitter.

Kyle Soppe: Lucas Duda, New York Mets

You're familiar with stacking a QB and WR from the same team in fantasy football, right? The idea being that such a roster construction essentially works as a multiplier, as production by your WR also goes to your QB. Similar logic should be applied when building a GPP MLB lineup, but it's not as obvious. It is reasonably safe to assume that Scherzer is going to be heavily owned tonight, so if you decide to fade him, why not buy in all the way? If Duda produces, not only do the points pile up for you, but they are being subtracted from every Scherzer owner. It's not a crazy play either, as only three pitchers have allowed more homers to lefties than Mad Max since the beginning of 2014, and 84.2 percent of Duda's bombs over that stretch have come against righties. I'll leave you with one last note and then let the defense rest: Aaron Judge. That is the entire list of the 247 players with at least 150 plate appearances this season that own both a higher ISO and a higher hard hit percentage than Duda this season.

Pitchers to build around

Eric Karabell: Joe Biagini, Toronto Blue Jays

Biagini hasn't won any of his past three outings, but each has been a quality start and with an average of six strikeouts as well. Those outings were against the Mariners, Yankees and Rangers. Now he faces the White Sox and it seems like he just needs to handle sizzling slugger Matt Davidson to get through another six strong innings. A win would be nice, but those can't be predicted. Biagini is priced nicely but he has surely been outpitching the price.

Tristan H. Cockcroft: Carlos Martinez, St. Louis Cardinals:

He has been absolutely filthy of late, posting a 2.11 ERA and 27.0 percent strikeout rate while averaging 27.7 DraftKings and 47.1 FanDuel points in his eight starts since May 1. It goes deeper than that: Martinez has been practically untouchable against right-handed hitters all year, limiting them to .187/.232/.310 rates while posting a strikeout rate more than seven percent higher and well-hit average 46 points lower than against left-handers, and the opposing Baltimore Orioles offense is rather righty-heavy.

Kyle Soppe: Junior Guerra, Milwaukee Brewers

There really aren't many pitchers I love tonight, so I will buy into what Guerra is selling. The matchup with the Padres (highest strikeout rate and second-lowest wOBA vs. RHP this season) obviously raises both his production ceiling and floor, but dig a bit deeper and you'll like this spot even more. Most will look at Guerra's league-leading strand rate of 91.6 percent and assume regression. That's not wrong, but with the Padres ranking 28th in wOBA with men on base this season, there is no real reason to assume that the imminent regression begins tonight. Guerra has struggled with his command at times, handing out at least three free passes in four straight starts, but the Padres rank as a bottom-five offense in walk percentage against righties this season. Every flaw of Guerra is a greater flaw for San Diego, something that makes him a far better play than his price tag indicates.
