Mountcastle went 1-for-4 with a two-run home run Thursday against the Red Sox.
Mountcastle got the O's going early, slugging his long ball in the bottom of the first inning. It was his first homer of the season and first extra-base hit since Opening Day. Though he's already racked up three runs scored and five RBI, Mountcastle is also hitting just .179 and will have to improve upon his 36.7 percent strikeout rate to return significant fantasy value.
