Los Angeles Dodgers manager Dave Roberts opened spring training Thursday with his confidence boosted by the acquisition of Mookie Betts, who could prove crucial to the franchise's quest to win its first World Series title since 1988. Betts, acquired from the Boston Red Sox this week in a multi-player deal, gives the Dodgers two recent MVPs in the outfield -- Betts, the 2018 AL MVP, in right and Cody Bellinger, the 2019 NL MVP, in center. Betts' potent hitting could provide scoring opportunities that weren't there during the Dodgers' run to the World Series in 2017 and 2018, Roberts said.
