The left-handed-hitting Stairs has a .286 average with two home runs and seven RBIs this season, and is 3-for-11 with two homers in his career against Burnett.
Things looked a little cloudy for Saturday against left-hander Andy Pettitte and Sunday against left-hander CC Sabathia until the Phillies announced after their 7-3 victory that they had called up right-handed-hitting outfielder John Mayberry Jr. from Triple-A Lehigh Valley.
Mayberry is expected to DH on Saturday and Sunday, although Phillies manager Charlie Manuel said he hadn't decided.
The Phillies optioned left-hander Sergio Escalona to Lehigh Valley to make room for Mayberry.
The Phillies had just two right-handed hitters on the bench: Eric Bruntlett, who is hitting .129 (4-for-31) with four RBIs; and Chris Coste, who is hitting .241 (14-for-58) with one homer and six RBIs.
