Fuller Dominates Brooklyn

Can someone tell me why James Fuller is still in A Brooklyn? Fuller, a 22 year old lefty out of Southern Connecticut State has dominated Brooklyn in the time he has been there. Last year in 8 games, 1 start, 18 innings, Fuller had an era of 1 with 22 strikeouts and opponents hit just .238 against him.

This year in 2 starts, 13 innings, Fuller is 2-0 with 13 strikeouts and just 2 walks. Fuller has shown that the hitters in the New York Penn League are no match. So I would suggest promoting him to A Savannah. He really cant do much better in Brooklyn so why not move him up...
