Billingsley, who is recovering from a pair of right elbow surgeries, could make two to three more rehab starts before potentially joining the Phillies' rotation before the end of the month.
Right fielder Domonic Brown went 0-for-2 with one strikeout in a rehab game with Class A Clearwater. He is 0-for-4 with three strikeouts in two games.
Outfielder Odubel Herrera said his left foot is finally OK after fouling a pitch off it Monday on Opening Day. But Phillies manager Ryne Sandberg decided to start Grady Sizemore in left field and Ben Revere in center field instead. Herrera appeared in Friday night's game against the Phillies as a pinch-runner in the seventh, scoring a run on Cesar Hernandez's pinch-hit two-run single, then played the final two innings in left field and grounded out in the eighth.
