The Boston Red Sox shook up the organization on Sunday by stunningly trading Rafael Devers to the San Francisco Giants just three years into his 10-year, $313.5 million deal. The decision to trade Devers ultimately seems to have stemmed from his unwillingness to put the team first when it came to his defensive position.

Devers, 28, did not resolve his problems with Boston’s front office. And on Sunday, the Red Sox made one of the most stunning baseball trades in recent memory, sending Devers to the San Francisco Giants for right-hander Jordan Hicks, left-hander Kyle Harrison, outfield prospect James Tibbs III and pitching prospect Jose Bello.
