Reyes' move is retroactive to March 26. Out because of a hyperactive thyroid, he is expected back in about a week.
Murphy's move is retractive to March 31, the day after he sprained his knee in a rundown. Murphy should be out until May.
Before Monday's opener, the Mets purchased the contracts of first baseman Mike Jacobs, left-hander Hisanori Takahashi and outfielder Frank Catalanotto from Triple-A Buffalo, and right-hander Jenrry Mejia and infielder Ruben Tejada from Double-A Binghamton.
