Top Projected MLB DFS Pitchers

Tonight's pitching slate offers a clear tier of dominant, front-line missing-bat aces alongside high-strikeout value options positioned to face highly vulnerable orders.

Roki Sasaki (LAD) at CWS: Sasaki represents an exceptional mid-tier value option on the mound tonight. Dating back to the start of May, he has registered a stellar 2.55 ERA while holding opposing batters to a tiny .186 average. He faces a White Sox lineup that carries the third-highest strikeout rate in baseball against right-handers.

Targeting supreme weather-driven environments and exploiting vulnerable platoon split liabilities is the ultimate key to solidifying your offensive core.

Oakland Athletics (vs. Sean Sullivan, COL LHP)

CRITICAL UPDATE: Left-hander Sean Sullivan has been called up to make his major league debut tonight rather than Zach Agnos. Sullivan has surrendered a massive .840 opposing OPS to righties and an .875 OPS to lefties at Triple-A this season. Playing in blazing 100-degree weather with winds gusting out in Las Vegas, elite power bats like Nick Kurtz (.261 ISO vs. RHP), Shea Langeliers (.211 ISO), and Brent Rooker are positioned for slate-breaking multi-home run upside.

Best Value Plays For DraftKings and FanDuel

Uncovering highly efficient, discounted options directly from the playbook allows you to prioritize front-line spending anchors across your roster.

Willi Castro (2B/3B, COL): Castro serves as a premier point-per-dollar core value play tonight. Slated to hit directly out of the high-upside leadoff spot against a left-handed starter, his strong .337 wOBA against southpaws provides an elite on-base floor in the best game total on the slate.
