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.
He was not in the starting lineup against the Houston Astros Saturday but manager Tony La Russa considered it.
Greene batted .325 with four home runs and eight RBIs while on a rehab assignment with Memphis.
Boggs was recalled Friday to start against Houston. He gave up two runs in five innings but walked five and threw 99 pitches.
