26-year old lefty swinging 1B Joe Koshansky is on fire in AAA but he’s blocked by Todd Helton on the Rockies. He has played in 65 games this season in AAA ball and he is 75 for 242 (.310 avg, 1.011 OPS) with 43 runs scored, 15 homers and 66 RBIs. He was the #17 prospect in the Rockies’ Minor League System when the season began according to Baseball America’s Prospect Handbook. If the Rockies don’t make a run soon they could look to trade Helton which could open an opportunity for Koshansky at the major league level.
