The Milwaukee Brewers have made an offer to Yu Darvish, according to a report.

Darvish appeared to confirm the news on Twitter. He tweeted a thinking face emoji along with a Japanese-language news report that the Brewers had submitted a formal offer to the free agent.

The original report cited "multiple insider sources," according to a translation, and said Milwaukee was one of six teams engaged.

Ken Rosenthal subsequently confirmed with his own source that the Brewers had submitted an offer.
