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.

Shohei Ohtani is expected to throw his first bullpen session this weekend as he returns from the elbow injury that prevented him from pitching in his first year with the Los Angeles Dodgers last season.
