The Mets claim Johan Santana is not injured, but his first Grapefruit League appearance has been pushed back by as much as two weeks.

He had originally been scheduled to make his first spring training appearance March 2.

"There's no structural issue," Sandy Alderson said. "It's just a matter of building up strength. So he'll be long-tossing before he gets back on the mound. We expect that his schedule will have been delayed somewhat."

Santana underwent shoulder surgery to repair a torn anterior capsule at the end of the 2010 season and missed the following year. He finished last season on the disabled list with lower-back inflammation and limited his throwing before arriving in camp.
