Vance Worley debuts, and a handful of relievers, including Jonathan Papelbon, Dontrelle Willis and Chad Qualls, make their second appearances of spring when the Phillies host the Astros beginning at 1:05 from Bright House Field. The game will air on The Comcast Network. Left-hander Pat Misch, a non-roster invitee and veteran of parts of six seasons with the Giants and Mets, also makes his Phillies debut. The hometown nine trots out a relatively full lineup: Rolllins SS, Victorino CF, Pence RF, Thome DH, Mayberry 1B, Nix LF, Frandsen 3B, Kratz C, Martinez 2B. This is Laynce Nix's first start in left. Willis and Qualls will try to rebound from shaky debuts Saturday. Other than that, the Phillies' pitching staff has looked strong, including seven pitchers combining on a seven-hitter in Tuesday's 7-0 win over Toronto.
