The San Francisco Giants could unlock their blockbuster trade addition with a "power slot" move the Boston Red Sox avoided.

BOSTON -- The Boston Red Sox traded slugger Rafael Devers to the San Francisco Giants on Sunday in a deal that could shake up pennant races on both coasts.

"We were all excited. We just swept the Yankees. We love our team and instead of being excited, I'm devastated," a fan told WBZ. "It's wild. We have traded Mookie Betts and Devers in the last five years. Our two best players and we got, essentially, nothing in return for either of them."
