What happened: López was scratched Saturday after hurting his left knee during pregame warmups. Martín Pérez replaced him and worked 6 2/3 no-hit innings.
Why it matters: The injury removes a starter who helped stabilize Atlanta’s rotation after a bullpen stint. It also creates another rotation decision before Monday’s trade deadline.
By the numbers: López has made 11 starts and 13 relief appearances in 2026. Ritchie would be making his eighth start and 14th overall appearance for Atlanta.
What to watch: Atlanta’s Monday off allows for an aggressive bullpen plan Sunday. The next update on López’s knee will clarify the rotation’s longer-term needs.
