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.

When the opportunity arose, the San Francisco Giants pounced. The Giants have a deal in place to acquire star slugger Rafael Devers from the Boston Red Sox for a four-player package, and they're taking on the $260 million or so owed to Devers through 2033.
