St. Louis ? The St. Louis Cardinals activated outfielder Roger Cedeno from the 15-day disabled list Friday night, and then designated him for assignment.

Cedeno was batting .158 in 57 at-bats with eight RBIs, five of them as a pinch hitter. He had been on the DL since June 6 because of a strained hamstring.

But the move didn’t mean a longer stay in the major leagues for Scott Seabol, who at 30 has been getting his first extended action.

Seabol was hitting .254 with one home run and eight RBIs in 59 at-bats, and has filled in at third base and the outfield, but in a bit of a surprise he was optioned to Triple-A Memphis after Friday night’s 8-1 victory over Pittsburgh.

Manager Tony La Russa said the team would recall utility player Hector Luna, who spent all of last season with the Cardinals as a Rule 5 draftee. Luna started at five positions last year.

“This will give us more flexibility,” La Russa said.

Seabol was shocked at the news.

“I don’t know what to say,” Seabol said. “They just told me to keep working.”

Besides his struggles with the Cardinals, Cedeno also had not impressed during a rehab stint with Memphis where he was 4-for-23 in eight games.
