Astros recalled RHP Jordan Lyles from Triple-A Oklahoma City.
As expected, Lyles will make the start Tuesday against the Phillies. The 21-year-old has a 3.49 ERA and 32/8 K/BB ratio over six starts at the Triple-A level this year and pitched well in a spot start against the Reds back on April 29, so he could have some NL-only appeal if he sticks around.
