Hernandez moved from center field to shortstop in the eighth inning Friday after Xander Bogaerts exited Boston's 7-3 win over the Mariners with a back injury.

EDGE Analysis

Hernandez filled in because Christian Arroyo was unavailable; Arroyo started in right field but was replaced by a superior defender in Jackie Bradley to start of the seventh inning. If Bogaerts is required to miss any time, Arroyo will likely fill in while Hernandez maintains his primary role as the team's starting center fielder.
