Ryan Mountcastle was made to wait nearly a month into the 2020 season for his major league debut. The Orioles ended that wait Friday.
With the date that will keep Mountcastle from accruing a full season of service time in 2020 and thus his free agency delayed for a year down the road as he toiled at the Orioles’ alternate training site in Bowie, Mountcastle will join the team for Friday’s game against the Boston Red Sox, according to a source. Mountcastle is the Orioles’ No. 5 prospect, according to Baseball America, and is expected to add some punch to their outfield and extend the middle of their top-heavy batting order.
