Harper (back) had seven at-bats on a back field Friday and hopes to play first base in Saturday's Grapefruit League game against the Yankees, Matt Gelb of The Athleticreports.

The 31-year-old was able to beat out an infield single, a good sign that the back stiffness that's sidelined him for the past week has subsided. Harper returning to action this weekend would quell questions about his availability for Opening Day.
