I give Plawecki credit too. Also the lineup for scoring 7 runs so far. Cora goes short leash when needed and in fact has excellent judgment on that.
Richards is on the verge of having 4 decent pitches: fastball, changeup (which isn't that great, actually), slider, and his big curve. I think the changeup needs to be slower to be effective. When ERod slowed his by 4-5 mph, it got much better.
