Ken Rosenthal is a well-respected news-breaker. He has sources, contacts, and all the things that make him first so often on breaking news. He’s the cream of the crop for baseball insiders.
So we don’t know exactly where this rumor came from, but Rosenthal is the one who wrote about it with a generic “What I’m Hearing” framing. We’ll give Ken the benefit of the doubt and assume someone really said this to him.
One possible scenario: Trade for Brewers second baseman Kolten Wong, a player the Dodgers like, according to major-league sources. Sign one of the big four free-agent shortstops.
