Two days after the Mariners dealt Alex Jackson, whom Baseball America had named the club’s top prospect entering 2016, it named his successor atop the list of top prospects in a once barren system.
Outfielder Kyle Lewis, Seattle’s first-round pick in 2016, topped BA’s list for 2017, followed by 21-year-old outfielder Tyler O’Neill and 20-year-old left-hander Luiz Gohara.
O’Neill and Gohara are mainstays from last season’s rankings, coming in fourth and sixth, respectively, but Lewis represents one of five new names on the list. Two other newcomers to the list, outfielder Mitch Haniger and right-hander Max Povse, were acquired in recent moves by general manager Jerry Dipoto.
