The Orioles acquired Pache and reliever Seranthony Dominguez from the Phillies in exchange for outfielder Austin Hays on Friday.
Pache has filled a short-side platoon role in center field for Philadelphia at times this season, and a similar role could await in Baltimore. Pache's strength is his defense with plus-three DRS in 50 games this season, but he hasn't offered much offensively in 2024 with a .202/.288/.269 slash line and 36.4 percent strikeout rate.
