The decision is partly a matter of comfort, with Ohtani and Yoshinobu Yamamoto accustomed to pitching essentially once a week dating back to their time in Japan. It also factored prominently, the Dodgers believe, into their ability to land phenom Roki Sasaki this winter — like his countrymen, Sasaki is used to pitching on a once-per-week schedule.

Ohtani says he will throw his first traditional bullpen session this weekend, at which point he will begin the process of preparing to join the Dodgers’ rotation, likely in May.

The Dodgers are hopeful that the real challenge for Shohei Ohtani this year won't be about his health, but rather his process of re-acclimating to the two-way role that made him a superstar.
