My approach to identifying lineups worthy of stacking evolved from fantasy football where I’d look at the opposing defenses fantasy points allowed to help identify positive matchups. For DFS baseball I look at a team’s DFS points per plate appearance (ppa) and compare to the opposing pitcher’s DFS ppa. A “bad” pitcher could lead to an increase in production from the hitters and conversely, a “good” pitcher could lead to a decrease in production.
How to Read the Charts
The Los Angeles Angels are facing a RHP at home (Jacob Turner DET who has faced 35 batters). On FanDuel the Angels are currently putting up 2.37 points per plate appearance (PPA) vs. RHP at home and Jacob Turner is currently allowing 196% more PPA than the MLB average (2.114 PPA). Their modified PPA is 4.64 (2.37 x 196%) and the difference is simply their modified PPA minus their situational PPA. Rinse & repeat for DraftKings.
It is important to note that due to the volatility of stolen bases, I do not include them when calculating ppa.
