Mariners' No. 1 prospect is batting .282 in 11 games for Class A Short Season Everett

Jackson swats his first home run of the year

The Mariners' No. 1 prospect finally broke through on Tuesday night.

That'd be Alex Jackson, the highly touted outfielder who is baseball's No. 22 overall prospect. Playing for Class A Short Season Everett, he connected on his first homer of the year, a two-run shot that provided the winning margin in the AquaSox's 5-3 win over Boise.

Still just 19 years old, the 2014 No. 6 overall pick is looking to find his groove in the Minors. He began the season with Class A Clinton, where he hit .157/.240/.213 with six doubles and 13 RBIs before being reassigned to extended Spring Training after experiencing shoulder pain in mid-May. Two weeks ago, Jackson began his current stint with Everett and has hit .282 in that time.

Tuesday was his first homer since last July with the AZL Mariners. Down in Arizona, Jackson flashed a .280/.344/.344 line while collecting 39 total bases in 23 games before he was sidelined due to a broken jaw courtesy of a line drive. Lauded as one of the top hitters in the 2014 Draft class, Jackson's prep career at Rancho Bernardo High (San Diego County, Calif.) included several All-America nods.

Jackson finished 2-for-4 with two RBIs against Boise and has hit in seven of his past nine games.
