When the Boston Red Sox traded Mookie Betts to the Los Angeles Dodgers on the eve of spring training, they broke up the ''Killer B's'' who patrolled the Fenway outfield and led the team to a World Series championship in 2018. Together, Betts, Jackie Bradley Jr. and Andrew Benintendi formed one of the best outfields in baseball and became fan favorites by following spectacular catches with their choreographed ''Win, Dance, Repeat'' postgame celebrations. Now, as the Red Sox learn to live without Betts, his former fellow outfielders are figuring things out with their new partner, Alex Verdugo, who came to Boston in the trade that send the 2018 AL MVP and pitcher David Price to the Dodgers.
