Tillman went a season-low 2 2/3 innings and was charged with a season-high five earned runs before being replaced by reliever Logan Verrett. Gardner took Verrett deep as part of a three-run fifth, which gave Yankees starter Luis Severino an eight-run cushion.
Severino went 6 1/3 innings, holding the Orioles to one run and striking out eight as he picked up his fourth victory of the year.
MOMENTS THAT MATTERED
Gardner, Holliday lead offense: The pair combined to drive in half of the Yankees' runs, with the early power surge setting the tone for a sluggish lineup.
