Cloyd replaces Halladay for Phillies
Phillies manager Ryne Sandberg says Halladay is experiencing flu-like symptoms. Halladay will start on Thursday.
Cloyd will make his first start since being recalled from Triple-A Lehigh Valley. In eight games and seven starts this season with Philadelphia, the right-hander is 2-3 with a 3.57 ERA.
His last major league appearance came in relief on Aug. 24, when he threw five shutout innings in an 18-inning loss to Arizona.
