The Phillies acquired Marsh from the Angels on Tuesday in exchange for catcher Logan O'Hoppe, Matt Gelb of The Athletic reports.
Philadelphia is buying low on the 24-year-old lefty-hitting outfielder, who was once a consensus top-100 prospect. Marsh is hitting .226/.284/.353 with eight home runs, eight steals and a 36.2 percent strikeout rate in 93 games this season. He gives the Phillies another potential option in center field to go along with righty-hitting Matt Vierling.
