Four sneaky Week 20 waiver targets surface as potential weekend embeds: Zebby Matthews, Hurston Waldrep, Cade Cavalli and Ben Brown. Matthews brings AFL-like strikeout upside and improving command, with a trendline that hints at a productive second half if his heater and slider calm the surface numbers. Waldrep has flashed swing-and-mip upside with a new split-finger look and a three-pitch mix that keeps hitters guessing. Cavalli returned from a long layoff with velocity gains and a sharpened knuckle curve, signaling he could handle a larger workload. Brown has found a modest two-start rhythm thanks to a heavier knuckle-curve usage, making him a deeper-league streaming option. Fantasy managers should monitor workload, matchup windows, and how each pitcher performs against mid-rotation lineups as August progresses, while keeping rosters flexible enough to chase surges in a thin starter market.
