Boston Red Sox manager Alex Cora has been sitting Mayer and Anthony against left-handed pitchers, but some are arguing that needs to change.

The Boston Red Sox have been trying to thread the needle between winning now and developing superstar prospects, and it's created sticky situations galore. Second baseman Kristian Campbell joined the team straight out of spring training and signed an eight-year extension shortly thereafter.

With the AL East leaders expected to start three left-handed starters in the series at Fenway Park, Alex Cora will turn to Rob Refsnyder and Romy González in his lineup.
