Warren put up a 9-K outing in Friday's win over Baltimore, his third consecutive quality start. He's a borderline SP2 in 12-team leagues now. If somehow he's still on your shallow waiver, this is the last claim window — Pitcher List is calling him the best 70%+ owned pitcher to buy.

Career-high 11 K with zero walks — the third double-digit K game of his career. Warren is making a strong case to keep his rotation spot even when Cole returns. 2.49 ERA through 5 starts. Must-roster in all formats.
