Andy Smith highlights the Nationals as an attractive DFS stack against Miami's Cal Quantrill. Quantrill had one concerning performance earlier in the season, allowing eight hits and six runs versus the Mets, despite his recent shutout innings. His xERA (4.98) and high hard-hit percentage (56.7%) suggest significant vulnerability. Nationals bats, including Nathaniel Lowe and James Wood, could exploit Quantrill's pitching flaws, providing strong upside for DFS lineups.
