Jon Jay was a serviceable outfielder for the last few seasons. He was the starting centerfielder for the 2011 World Series team after Colby Rasmus was traded in July. He hits close to .300 and plays a decent centerfield, but has little power. With the emergence of Randal Grichuk, Tommy Pham, and Stephen Piscotty, Jay saw very little playing time the second half of 2015.
With the trade of Jay and Tony Cruz last week, the Cardinals no longer have any members of the self proclaimed "Memphis Mafia". David Freese, Allen Craig, Daniel Descalso, Jay, and Cruz all played together in Memphis before being promoted to St. Louis. Excluding Cruz, the other four played big roles in the 2011 World Series. At least they all will have a World Series ring when they retire.
