With Blake Snell's return from the IL, Roki Sasaki is the last star member of the Dodgers' rotation left on the IL (apologies to Tony Gonsolin). In the starts he was able to make, Sasaki was far from living up to the mammoth expectations placed on him in his first MLB season, and then he hit the IL on May 13 with a shoulder impingement after just eight starts.
His return has been rocky. He's started and stopped a throwing progression a few times already, and Dave Roberts has provided conflicting and oftentimes unhelpful updates on whether or not Sasaki will be back this year at all.
