Third baseman D.J. Peterson, the Mariners' No. 3 prospect, homered twice and drove in five runs Monday, as Double-A Jackson defeated Montgomery, 13-6, in their season finale.
Peterson, ranked No. 52 on MLBPipeline.com's Top 100 Prospects list, finished the day 4-for-6 and scored twice. He matched his career high for hits and recorded his fourth multi-homer game of the season.
The Mariners selected Peterson with the 12th overall pick of the 2013 First-Year Player Draft. He began his first full professional season with Class A Advanced High Desert and earning a promotion in June. In 123 games between the two levels, Peterson hit .297/.360/.552 with 31 home runs and 111 RBIs. He led all Mariners in home runs, edging High Desert outfielder Jabari Henry, who finished with 30 in 114 games.
Jackson didn't make the Southern League playoffs, bringing its season to a close Monday. Peterson still has baseball left to play this year, however. It was announced last week that he is among the contingent the Mariners are sending to the Arizona Fall League next month, where they will play for Surprise along with players from the Padres, Rangers and Red Sox.
