MIAMI -- The Phillies shook up their pitching staff with roster moves prior to Saturday's game against the Marlins.
Philadelphia optioned right-hander David Buchanan to Triple-A Lehigh Valley and called up left-hander Elvis Araujo from Double-A Reading. Araujo, who signed a Major League deal with the Phillies this past winter, will join the ballclub on Sunday in Miami for the series finale.
General manager Ruben Amaro Jr. also announced that righty Chad Billingsley will return from two elbow surgeries to start Tuesday's game against the Braves in his first big league appearance since April 15, 2013.
