Over the last couple of weeks, Rusney Castillo has made a smooth transition to left field, and looks primed to hold down that spot for Boston in 2016.
So now the only question is how to align Bradley and Betts.
Bradley has mainly played right field of late, but got the nod in center on Wednesday as Betts had the night off.
"We all know Jackie is comfortable in center," said interim manager Torey Lovullo. "Jackie is comfortable no matter where you put him."
So what type of things are the Red Sox trying to evaluate with Betts when he plays in right?
"We're probably looking at Mookie's first steps, Mookie's coverage, his reads," said Lovullo. "It's more about Mookie in the situation of being a right fielder than it is Jackie being a center fielder. We feel fine about arm strength. Everybody is concerned about the right fielder's arm strength. We know that Mookie has really improved in that area. That's not really going to be an issue for me.
"I think it's mostly about his first-step reads and gaining ground on the ball. And you can see what he's doing in center field. We look for that to be the same in right field."
