10 names to add this weekend that can tilt fantasy baseball playoff outcomes, led by Brandon Fott and Parker Meadows. The guide leans into streaming mindset with a mix of ugly-at-first pitchers and power-hitting additions designed to push points and wins in the final stretch.

Key pitchers include Slade Cecconi, JT Ginn, and Michael Lorenzen, with matchup-based upside and risk management in play. On the hitting side, Tyler Stevenson, Ivan Herrera, Josh Bell, and Parker Meadows bring power and run production at catcher and corner spots, offering multi-category boosts even in shallow leagues.

Ownership, park factors, and start timing drive the plan as the host maps starts and forecasts, delivering a standalone weekend strategy that stands apart from the usual lineups.

September rosters expanded to 28, and a flurry of callups and debuts reshapes fantasy value for the final month. Jordan Lawlar and Sal Stewart headline the prospects promoted by Arizona and Cincinnati, while Kevin Alcántara and George Valera are newly in-season fixtures with Cubs and Guardians. Payton Tolley and Jonah Tong delivered electric debuts for the Pirates and Mets rivalry week, and Sandy Alcantara is back to the form that boosted fantasy rosters all season. The Mets ride Juan Soto’s torrid stretch as their offense surges, and rosters churn continues with more rookies joining the mix as teams chase playoff spots.

Promoted hitters and pitchers mix with injury notes and bullpen shuffles, adding depth but also risk for fantasy owners. Masyn Winn’s health and return to action for St. Louis, plus Drew Gilbert's fresh look with the Giants, spotlight the evolving landscape of September value. The waiver wire stays active as veterans and rookies alike push for at-bats, with Cal Raleigh and other backstops offering streaming potential in deeper formats.

Kyle Schwarber exploded for four homers in a single Phillies win, elevating his season arc and reviving a narrative around NL MVP chatter with Otani’s two-way star power looming large. The episode weaves in Schwarber’s improved lefty splits, power consistency, and clubhouse impact, while threading in breakout rookie journeys (Tolley, Tong, Mlan, Rashi) and big-picture MVP debates that hinge on home-run tempo, mound performance, and free-agent ceilings.

Debuts and prospect chatter steal some spotlight: Tolley’s Sox call, Tong and Mlan’s Mets arrivals, and Rashi’s Diamondbacks splash paint a promising immediate impact vibe for a league chasing playoff depth. Intermittent NYC attendance talk and Abbott Elementary cameos add color to a week that balanced historic feats with the shifting sands of teams’ futures and star valuations.

September call-ups loom as fantasy rosters inch toward playoffs, offering a slate of potential difference-makers who can swing weekly outcomes. In the spotlight: Jordan Lawlar, Jacob Wilson and Jasson Domínguez, each positioned to contribute early with big minors pedigree and the right developmental timing. The window is tight; owners should pounce on hot starts, especially when streaming for short-term boosts in runs, RBIs and power.

Lawlar, 23rd overall prospect, has a 319/.319 line across 229 minor at-bats with 50 runs, 21 doubles, 5 triples, 10 homers and 46 RBIs plus 19 steals. Wilson ranks at .312 with 46 runs, 17 doubles, 10 homers and 78 RBIs across 369 at-bats, offering multi-position value. Domínguez, the high-profile call-up archetype, has shown the ability to swing a season—his early impact is a reminder to chase up-front bets rather than late waiver adds.

Other immediate-need names show upside too: Chase Burns could carve a relief-to-spot-start path for Cincinnati, Kyle Bradish might return with a sharp boost for Baltimore, and Mick Abel offers fantasy-friendly peripherals if Philadelphia leans on him down the stretch. The strategy: stash the high-upside rookies, stream when matchups align, and ride the breakout weeks without overpaying for expected stumbles.
