Outfielder Alex Jackson, the sixth overall pick in the 2014 First-Year Player Draft, hit his first professional home run Monday in the Rookie-level Mariners' 8-6 defeat to the Reds in Arizona League action.
Facing left-hander Ty Boyles with two outs in the fourth inning, Jackson drove a two-run blast out to center field. He finished the game 1-for-4 with two runs, a walk and two RBIs.
Outfielder Gareth Morgan, the Mariners' second-round pick, hit in front of Jackson. He went 0-for-4 with a walk and four strikeouts.
Jackson's first home run came in the 10th game of his career. The 18-year-old is hitting .325/.378/.550 with seven runs and nine RBIs. Six of his 13 hits have gone for extra bases.
The Mariners drafted Jackson out of Rancho Bernardo High School in San Diego. He was a primarily a catcher in high school, but the Mariners have moved him to the outfield to allow his advanced bat to progress more rapidly through the Minor Leagues. He played right field Monday and has also spent some time in left field.
