Orioles' Gunnar Henderson: Sitting out with back issue

Henderson (back) is absent from the lineup for Wednesday's tilt in Philadelphia, Roch Kubatko of MASNSports.com reports.

Henderson was forced to depart Tuesday's loss to the Phillies with lower back discomfort. He's feeling better, though, and expects to be ready to go Friday versus the Yankees following Thursday's off day. Jorge Mateo is at shortstop Wednesday.
