Ryan O'Hearn made his major league debut with the Kansas City Royals on July 31, 2018, four years after having been an 8th-round pick in the 2014 amateur draft out of Sam Houston State University. He had a good debut, going 1 for 3, with the hit a home run in a 4-2 win over the Chicago White Sox. He also drew a walk, scored 2 runs and drive in 2 while playing DH. However, things went sour after that and heading into his 8th game on August 13th, he was hitting just .130. He reversed that with another solid game; in this one he drove in all three runs in a 3-1 Royals win over the Toronto Blue Jays. Facing Sean Reid-Foley, who was making his big league debut, he hit a two-run opposite field homer in the 2nd, then in the 4th drew a bases-loaded walk. He played a lot better from that point on, finishing the year at .262 with 10 doubles, 12 homers, 23 runs and 30 RBIs in 44 games, good for an OPS+ of 155.
