Ryan Mountcastle hit a two-run homer in the fourth to help the Orioles wipe out an early three-run deficit with a five-run outburst. Mountcastle added another two-run homer the next inning and finished with five RBI, helping the Orioles to an 11-7 victory over the Royals — and a 10th consecutive series-opening win. The Orioles finished with 15 hits to go with eight walks against Kansas City pitching.
Ryan Yarbrough (0-4) matched a Royals record by striking out the first five Baltimore batters, including Mountcastle, before things fell apart in the fourth.
