Streaming SP: Walker Buehler (RHP, SD vs CHC, 6% owned) is your top under-50% streaming target today—San Diego gets a favorable matchup against Chicago, and Buehler's comeback arc makes him a calculated risk in shallow leagues. Waiver Priority: Chase Lee (recalled by Toronto from Buffalo) warrants a speculative add at minimal ownership; young RHP callups can provide emergency depth if injuries strike. Buy-Low Target: Keider Montero (ownership unknown) has a 70.77 regression score with ERA (3.68) significantly elevated over FIP (1.97)—his underlying metrics suggest ERA regression down, making him a prime trade candidate in standard leagues. Bullpen Watch: Aroldis Chapman (BOS), Emilio Pagán (CIN), and Victor Vodnik (COL) are all primed for save opportunities tonight after resting 2+ days, with Chapman the most widely rostered. IL Update: Phil Maton (CHC) and Christopher Morel (MIA) both returned yesterday, with Maton's bullpen slot providing immediate ceiling value in mixed leagues.
