Keston Hiura began the 2018 season with the High-A Carolina Mudcats, and in 50 games hit .320 with seven homers. He was then moved up to Double-A Biloxi where he struggled more than he did in High-A, but still hit .272 with six homers in 73 games. Hiura did experience elbow issues as well during 2018.
However, in the Arizona Fall League Hiura ripped the cover off the ball. His average was .333 and came with 32 RBI’s in only 21 appearances. He is one of only a handful of players to hit that many RBIs in the AFL.
