Last year, the Dodgers declined to extend the $21.05 million qualifying offer to homegrown kid Walker Buehler, reportedly so as to not hurt his market in free agency. They were suggested to have been working on a reunion with Buehler early in the offseason, but he opted instead to sign with the Red Sox on a one-year, $21.05 million deal — exactly the same as the QO. By then, the Dodgers had already pivoted to Blake Snell.
Buehler's "one year in Boston" turned out to be more like 3/4 of the year there and the other 1/4 in Philadelphia, after the Red Sox DFA'd him in late August.
