Alex Jackson officially signs, takes BP today
The Mariners officially announced the signing of first-round Draft pick Alex Jackson as the club arrived back home to begin a six-game homestand.
Jackson, 18, was given a locker in the team’s clubhouse at Safeco Field for the day and will take batting practice with the team prior to Monday night’s series opener against the Red Sox.
Jackson, who agreed to a signing bonus of about $4.2 million, will report to the rookie-level Arizona League Mariners in Peoria on Tuesday.
Jackson played primarily catcher for Rancho Bernardo High School in San Diego, but will begin his professional career in the outfield for the Mariners after being the sixth overall pick in the 2014 First-Year Player Draft.
Jackson hit .400 (40-for-100) with a 1.459 OPS and 45 runs scored, seven doubles, four triples, 11 home runs and 31 RBIs in 35 games during his senior season at Rancho Bernardo. The 6-foot-2, 215-pounder was rated as the top position player in the draft and fourth overall prospect by Baseball America.
Jackson was named to the 2014 Perfect Game All-American first team and the California All-Region first team after his senior season. In four seasons with Rancho Bernardo, Jackson batted .375 with 156 runs scored, 35 doubles, six triples, 47 home runs and 127 RBIs in 135 games.
His 47 prep career home runs tied him with former Indians prospect Johnny Drennen (2002-05) for the all-time San Diego section record. Jackson had five homers as a freshman, 17 as a sophomore, 14 as a junior and 11 during his senior season. Jackson’s team played for California’s San Diego section championship in all four of his high school seasons, including winning the championship during his freshman and junior seasons.
