Phillies signed RHP Oscar Villarreal to a minor league contract.
Updating a previous report, Villarreal will not be invited to major league camp, as he is still rehabbing from Tommy John surgery. Villarreal, 28, last posted a 5.02 ERA in 37 2/3 innings in his last healthy season with the Astros in 2008, but boasts a 3.86 career ERA.
