The Astros are expected to promote a few more players within in the next week to see how they perform at a higher level for the final few weeks of the Minor League season, general manager Jeff Luhnow said.
"We're going to place prospects at the level we think they need to get accustomed to for next year," Luhnow said. "That will put us in a good spot for the remainder of the year."
Springer is one of the reasons the Astros' farm system is now considered on the rise. The farm system has improved considerably the last two years through trades and the Draft.
Houston's top four Minor League clubs had a combined record of 255-210 (.548) entering Thursday, which is the most drastic improvement of any organization from 2011 to 2012. Luhnow said he wants to make moves that won't jeopardize the clubs' chances of winning a title.
"We do need to be cognizant of not stripping a team of what's making it successful so far this year," Luhnow said. "We also want guys to have an opportunity to experience what it's like to win a championship in the Minor Leagues. I have six Minor League rings from my time in St. Louis, and I want to start accumulating those here as well.
"It creates an attitude, an expectation, a mindset that's healthy for the whole organization. These guys come up and they have a chance to win together. It makes a big difference in how they start here."
