The Potomac first baseman earned the Carolina League’s Topps Player of the Month honors for the month of July by a poll of the managers.
The former first round pick batted a whopping .354 in the month with five bombs and 17 RBI. That puts his season numbers to .296/.370/.484 with 16 homers and 62 RBI in 103 games.
The Nationals selected the 21-year-old as a raw power-hitting prospect out of high school. Marrero has often been considered to have a naturally fast bat but poor hitting for contact, and poor consistency.
In 2007 he earned a lot of attention as he combined between high and low A ball while hitting .275 with 23 home runs and 88 RBI. He was named by Baseball America as the top prospect in the organization for 2008.
Marrero however has seem to be stuck in Single A. In 2008 he battled injuries and only hit .250 with 11 homers and 38 RBI in 70 games. While still in Single A it seems Marrero has found his stroke again with his hot July and he may earn a promotion to Double A soon.
The Nationals have recently said they hope he can make the big league club by 2011.
