He did try for Ohtani. With that said, it does not seem he tried at all for Yamamoto, unless I've missed some reporting over the last 4 days. The Cubs bowed out of Yamamoto, seemingly, at the start of the offseason, once it became clear the original projection of around $200-250m wasn't happening. The last I saw, the Cubs had no meetings with Yamamoto, and Hoyer's comments in an Athletic article on Yamamoto were...luke warm. Not really saying anything to the rest of the post, or what the Cubs should have done on Yamamoto, only that I wouldn't say he tried there in the same way he did for Ohtani. Ohtani it appears the Cubs offered something around what was necessary. Yamamoto, the Cubs bowed out well before.
