The second hit forced Miley out after just 12 pitches and brought on Gabriel Ynoa, who was recalled from Triple-A on Thursday.
The bizarre line-drive sequence was the latest in a crazy week for Baltimore, which has shuffled around its pitching to try to cover for Kevin Gausman, who was ejected in the second inning of Wednesday's game. The O's, who optioned Thursday's emergency starter Tyler Wilson before Friday's game, have had just one "normal start" of at least five innings by a regular member of their rotation in their past five games.
