12-game MLB slate primes a Diamondbacks-heavy weekend with Coors Field hosting Arizona power. Framber Valdez anchors cash-game consideration, while Framber Valdez and Charlie Morton stand out for run prevention and strikeouts. Midrange upside comes from Jacob deGrom, Yusei Kikuchi, and Luis Gil. Ketel Marte, Corey Seager, and Corbin Carroll headline a high-upside Arizona stack, with Warming Bernabel and Geraldo Perdomo providing cheap access. In the outfield, Carroll, Brent Rooker, Roman Anthony, and other value plays populate lineups. Stacks focus on Arizona at Coors, Boston against Alcantara, and Colorado against Brandon Pfaadt, capped by a balanced mix of stars and value.

The slate emphasizes chasing the Coors backdrop for Dbacks, Boston's leverage against Alcantara, and Rockies' upside against Pfaadt. The article groups pitchers by reliability, midrange upside, and salary relief, then blends in a handful of hitters who are locked in or trending hot. The recommended approach blends elite arms with dual-threat bats and a few cost-efficient infielders/outfielders to optimize DK and FD rosters for Friday’s late games, while keeping an eye on weather and starting-lineup updates.

Overall, the piece positions Arizona as the core pivot, with Carroll as the crown jewel, Marte fueling stacks, and Perdomo/Del Castillo offering cheap exposure. The recommended paths balance risk and reward—Valdez for cash, deGrom/Kikuchi/Gil for upside, and a Diamondbacks-heavy approach in Coors with supportive cores from Boston and Colorado stacks.
