TORONTO — Home plate umpire Dale Scott was hit in the face mask by a foul tip from Baltimore slugger Mark Trumbo on Friday night, casting a shadow over the Orioles’ 6-4 victory over the struggling Toronto Blue Jays.

Scott recoiled after the ball struck the bottom of his mask and staggered backward before going down on one knee in the eighth inning. After being examined by Blue Jays trainer George Poulis, the veteran crew chief lay down on his back on the turf behind home plate and received further attention from paramedics and Toronto’s team physician, Dr. Irv Feferman.

Once his neck was immobilized on a spinal board, Scott was lifted onto a cart and driven off the field. The game resumed with second base umpire Brian Knight working behind home plate.

J.J. Hardy hit a two-run homer for first-place Baltimore, which improved to 4-0 against Toronto. Chris Davis, Jonathan Schoop, and Seth Smith also connected, and Wade Miley (1-0) pitched six innings for his first win of the season.
