SEATTLE -- Alex Jackson and D.J. Peterson, the Mariners' first-round Draft picks the past two years, are both rated among the top 50 prospects in baseball in the newly released MLB.com rankings.
Jackson debuts at No. 28 in MLB.com's Top 100 Prospects list that came out Friday night on MLB Network, while Peterson is No. 50. They are the only two Mariners on the list, with Seattle having seen several of its previous highly-rated youngsters promoted to the Major League club in the past year and thus no longer carrying prospect status.
