EDGE Analysis

After some initial uncertainty, the Astros have officially decided to send McCormick down to the minors for some at-bats before bringing him back onto the major-league roster. It's unknown how long the team plans on keeping him on assignment, but if all goes well it's possible the 28-year-old outfielder returns within a week or so.
