Miller will hit sixth and play first base against Boston on Friday, Marc Topkin of The Tampa Bay Times reports.
Miller didn't earn a start against Chris Sale on Opening Day but will get into the lineup versus fellow left-hander David Price for the second game of the Rays' opening series. He did wind up coming into Thursday's contest as a pinch hitter, walking in a run and then scoring during the club's six-run eighth inning. Expect to see Miller in the lineup against right-handers and occasionally with lefties on the mound.
