What happened: Dave Roberts said the torque of landing while pitching aggravates Ohtani's knee. The Dodgers canceled his planned Wednesday start after he felt discomfort during catch play.

Why it matters: Los Angeles must Blake Snell has begun a rehab assignment, with bullpen games and spot starts among the short-term options.

What to watch: The Dodgers will wait until Ohtani can pitch without risking a setback. Roberts still expects him to return to the mound this year.
