Interestingly I just saw this -
McCaffrey and Rosenthal's report also revealed something critical: the specific reason the Red Sox's offers to Minnesota weren't enough to pry Ryan loose, as well as one name they were confirmed to be willing to give up.
"As the minutes ticked closer to Thursday’s 6 p.m. ET trade deadline, the Boston Red Sox reached out to the Minnesota Twins about coveted starter Joe Ryan. But according to league sources briefed on discussions from the Twins’ side, talks fell apart when the Red Sox were unwilling to offer any of their big league outfielders, or an enticing enough package of their top-tier prospects," wrote McCaffrey.
"Jhostynxon Garcia, the Red Sox’s top outfield prospect, was in the mix to be in the deal. But despite Boston’s highly-regarded farm system, sources said that the rest of the haul offered was not substantial enough to land Ryan, owner of a 2.82 ERA and whose value is enhanced by being under team control through 2027."
So reading between the lines, it seems as though a package that included either of two outfielders, Jarren Duran and Wilyer Abreu could have gotten the job done. And perhaps another path existed if prospects like shortstop Franklin Arias or left-handed pitcher Payton Tolle were included, though we can't say with certainty that they weren't.
