St. Louis ? The St. Louis Cardinals activated shortstop Khalil Greene from the 15-day disabled list, and optioned right-hander Mitchell Boggs to Triple-A Memphis. Greene has had two stints on the disabled list because of social anxiety disorder and has been limited to 47 games in his first season with St. Louis. He’s hitting .200 with five home runs and has committed eight errors. He is hitless in his last 16 at-bats.
