Third baseman D.J. Peterson, the Mariners' No. 3 prospect, collected four hits and drove in five runs in two games Tuesday, helping Double-A Jackson split a doubleheader at Huntsville.
In the first game, Peterson hit two home runs to lead the Generals to a 6-2 victory. He homered in back-to-back plate appearances against Huntsville starter Jed Bradley, first going deep in the third and then again in the fourth. He finished the game 2-for-4 with two runs and four RBIs.
In the nightcap, Peterson went 2-for-3 and drove in Jackson's lone run, but it wasn't enough for a victory. The Generals lost, 2-1, in eight innings.
Peterson, ranked No. 52 on MLBPipeline.com's Top 100 Prospects list, began the season with Class A Advanced High Desert and earned a promotion in June. Since joining Jackson, he is hitting .257/.340/.474 with 10 home runs in 46 games.
The Mariners selected Peterson with the 12th overall pick in the 2013 First-Year Player Draft. Since then, he has hit 41 home runs in 166 games at four levels of the Minor Leagues. Among 2013 draftees, only Kris Bryant, the second overall pick, has hit more home runs as a professional. The Cubs' top prospect has bashed 49 home runs since signing.
