Springer off to a great start with the Lancaster Jethawks --high class A minors for the Texas Rangers. Two for four with a grand slam in the 6th. Box score
Think you meant Houston Astros - Not Texas rangers (Mike Olt is w/ Rangers). Not thinking he will be in A ball long.
I was able to track down audio of Springer's slam for my blog: Farmstros. The call is from the opposing team so it lacks a little enthusiasm you might expect, but it still gives a chance to hear Springer do his damage.
