Houston was without both Cedeno and outfielder Brandon Barnes (ankle) in Friday's game, which left manager Bo Porter shorthanded. Barnes appeared in Saturday's game and returned to the lineup Sunday as the starting center fielder. He said he was 100 percent.
Porter didn't reveal he was without Cedeno and Barnes until after Friday's game for strategic reasons, but Cedeno's unavailability Sunday was obvious when he was scratched from the lineup.
"Marwin is still a little shaken up in the collision he had at first base, but with Ronny being unavailable, he's going to have to play shortstop today," Porter said.
