Dodgers!

[CalBears96]

history suggests pitchers of relative small frame (under 6 ft) don't have longevity....if he opts out after year 6 Dodgers will probably dodge a bullet, but would've enjoyed age 25 to 31 seasons before his body start to break down

It would be a good thing if Yamamoto were to opt out after year 6 because that would mean he's had 6 good years, and hopefully the Dodgers had taken advantage of those 6 years, like if Ohtani and Betts also had good years simultaneously.
