Red Sox trade All-Star slugger Rafael Devers to Giants - ESPN

The San Francisco Giants acquired three-time All-Star Rafael Devers from the Boston Red Sox on Sunday in a stunning trade that sent a player Boston once considered a franchise cornerstone to a San Francisco team needing an offensive infusion.

Boston received left-handed starter Kyle Harrison, right-hander Jordan Hicks, outfield prospect James Tibbs III and Rookie League right-hander Jose Bello.

The Red Sox announced the deal Sunday evening.

The Giants will cover the remainder of Devers' contract, which runs through 2033 and will pay him more than $250 million, sources told ESPN.

The trade ends the fractured relationship between Devers and the Red Sox that had degraded since spring training, when Devers balked at moving off third base — the position where he had spent his whole career — after the signing of free agent Alex Bregman. The Red Sox gave no forewarning to Devers, who expressed frustration before relenting and agreeing to be their designated hitter.

After a season-ending injury to first baseman Triston Casas in early May, the Red Sox asked Devers to move to first base. Devers declined, suggesting the front office «should do their jobs» and find another player after the organization told him during spring training he would be the DH for the remainder of the season. The day after Devers' comments, Red Sox owner John Henry, president Sam Kennedy and chief baseball officer Craig Breslow flew to Kansas City, where Boston was playing, to talk with Devers.

In the weeks since, Devers' refusal to play first led to internal tension and helped facilitate the deal, sources said.

San Francisco pounced — and added a force to an offense that ranks 15th in runs scored in Major League Baseball. Devers, 28, is hitting
