The Los Angeles Dodgers announced the signing of star outfielder Mookie Betts from the Boston Red Sox on Monday, sealing a blockbuster deal that had teetered close to collapse over the weekend. Betts, the 2018 American League MVP, heads to Los Angeles along with former Cy Young Award-winning pitcher David Price and cash in a deal that sees three top Dodgers prospects head the other way. News of the deal had first emerged last week, with the Minnesota Twins also involved in the complicated transaction.
