HOUSTON -- The Phillies announced their World Series roster on Friday morning, less than eight hours before first pitch in Game 1 of the World Series against the Astros at Minute Maid Park.

The Phillies made two changes to their roster from the National League Championship Series. Infielder/outfielder Nick Maton replaced outfielder Dalton Guthrie. Maton hits left-handed, so it gives the Phils a little more flexibility on the bench against an Astros pitching staff that carries only one left-hander in the bullpen: Will Smith.

Right-hander Nick Nelson replaced left-hander Bailey Falter as the second change. The Astros ranked second in the Majors this season with a .783 OPS against left-handed pitching. They ranked ninth with a .726 OPS against right-handers. Falter allowed three hits and four runs in two-thirds of an inning in his Game 4 start in the NLCS against San Diego.
