Travis Jankowski and Alex Dickerson have played significant time for San Diego the latter half of the current season, and have made big strides toward establishing themselves as capable big-league starters. Hunter Renfroe looks likely to put the finishing touches on a .300/30/100 season at El Paso before his September call-up. Jabari Blash remains one of the more intriguing prospects because of his light-tower power. And AAA center fielder Manuel Margot among the top prospects in all of baseball.
