Your prime DFS stack choices for the Friday slate.
1.) Boston Red Sox Stack
Gregory Soto is the worst pitcher on this slate and he gets a powerhouse offense in the Boston Red Sox. He has a .390 BAA, eight home runs given up and a 11.51 ERA at home this season. The usual Boston stack suspects are who I want, Betts and Martinez. I don’t mind Devers since Carpenter has been horrible against lefties. I also love Benintendi in this one as I see a nice multi-hit game coming out of him.
2.) Washington Nationals Stack
Brad Keller started off this season very strong and then something clicked and he turned into who he really is, a trash can. On this road this season he holds a 5.08 ERA and a .281 BAA. He also has a sub seven K/9 so a lot of balls are being kept in play. He is equally horrible to both sides, but he does walk lefties more than righties. That gives me more love for Adam Eaton as that ups his potential for stolen bases. Pair him with Juan Soto, Anthony Rendon and Trea Turner in this stack.
3.) Minnesota Twins Stack
Surprisingly Adrian Sampson has been really good in Texas and HORRIBLE away from Texas. Away from Texas he holds a 6.47 ERA and a .306 BAA and .604 SLG. Sampson has also been reverse splits this season, so I love Nelson Cruz for a deep ball in this one. I also don’t mind Eddie Rosario, Jorge Polanco and my all time favorite Twins stack tournament play, Max Kepler.
4.) Houston Astros Stack
I’m not sure who the opening pitcher is going to be here, but we do know that Felix Pena is going to follow. Pena has been especially worse against left-handed bats this season (.281 BAA, right home runs given up). I’m especially looking at Yordan Alvarez and Michael Brantley in this stack. Obviously you can round out this stack with Alex Bregman and Jose Altuve.
