In an Instagram post published Tuesday night, the father of two wrote, "I've waited long enough. 4 years have come and gone, but what a ride it was. Thank you to the Astros, my teammates, coaches, staff, and of course the FANS. Houston will always be special to me."

"We talk about it all the time -- away from the ballfield, obviously," Reddick told ESPN in October. "We're trying to ride this wave and enjoy it as much as possible."
Reddick makes up part of an entire starting outfield that will venture into the free-agent market this offseason, alongside Michael Brantley and George Springer, the homegrown superstar who will join J.T. Realmuto among the most coveted free agents.
