With center fielder Jackie Bradley Jr. and right fielder Mookie Betts having breakout years, the best fit for Benintendi -- ranked as Boston's No. 3 prospect by MLBPipeline.com -- appears to be in left field. It also leaves open the possibility of Benintendi making his Major League debut this season.
"With Andrew going to left, we are looking down the road a little ways," Red Sox manager John Farrell said. "When that day comes and he's a left fielder here in Boston remains to be seen, but the way he's swung the bat, the way he's advanced this year, you start to prepare for it, for that eventual day."
The 22-year-old was hitting .304 with seven home runs and 65 RBIs between High Class A Salem and Portland entering Saturday.
Farrell noted that the Red Sox are content to keep super utility player Brock Holt in left field, given their success when he plays the position. The club also recently moved Blake Swihart to left field. However, the converted catcher has been on the disabled list since June 5 with a severe left ankle sprain.
