Four Week 22 waiver targets spark fantasy rotations: Cam Schlittler in New York has a late-August surge (2.08 ERA, 0.97 WHIP, 23:7 K:BB in 21.2 IP) powered by a cutter and curve that miss bats and sharpen command. Ryan Bergert in Kansas City has a 2.73 ERA, 1.03 WHIP since August, riding a higher-use sweeper off the slider to fuel strikeouts. Cade Cavalli in Washington shows untapped K upside with a lethal knuckle-curve mix and favorable chase rates; Braxton Ashcraft in Pittsburgh has three solid August starts, with a slider gain driving the elite numbers. Target these four for the stretch run.
