Waiver-wire season accelerates into next week with a clear focus on one-week streams and Coors Field heroes. Severino sheets a favorable road start against Pittsburgh, while Rengifo and Moncada offer multi-cat upside in deeper leagues. Alexander latches onto a two-start slate vs Texas and Seattle, and Rockies core Beck, Freeman and Karros thrive at altitude, complemented by the speculative power/speed splash from Otto Lopez, Mickey Moniak and Sean Burke as potential budget adds.
