Any consideration for a September promotion that the Cardinals planned to give top prospect Oscar Taveras will end next week when the outfielder has surgery to address persisting pain in his right ankle.

The procedure will end his season before it had much of a chance to begin.

Taveras 21 has missed all but 46 games with Class AAA Memphis this season because of a high ankle sprain that has twice placed him on the disabled list and as recently as Monday forced him from rehab with soreness. Taveras will have arthroscopic surgery on the joint next week to determine the extent of damage and the team will have a feel for his recovery after the procedure.

“I don’t think I’d term it as a ‘lost’ season” general manager John Mozeliak said. “It’s obviously disappointing in the sense that he didn’t get the at-bats. I still think when he played he played well. It’s unfortunate. Injuries happen in this game and this one doesn’t seem to be to the point where we’re going to have to worry about next year.”

Taveras came to major-league spring training this year as one of the top hitting prospects in the game universally considered a top-five prospect by trade publications like Baseball America. A native of the Dominican Republic Taveras had played for a championship club at three different levels in each of the past three seasons and the Cardinals expected him to make his major-league debut at some point this season.

He hit .306 with five home runs and 32 RBIs in 173 at-bats for Memphis and slugged .462 with the Redbirds. On May 12 he turned his ankle and that started a summer spent mostly trying to get back on the field.

The Cardinals said within the past week that they hoped to have Taveras on a rehab assignment by this weekend and back with Memphis before the end of the minor-league season. Mozeliak said Taveras felt a reoccurrence of the pain above his right ankle Monday and flew to Charlotte N.C. to consult with a specialist Tuesday. Dr. Robert Anderson “recommended a scope just because of three months of not getting better” Mozeliak said. Anderson performed the ankle surgery this past offseason on Yankees shortstop Derek Jeter.

The scope procedure will reveal the extent of the irritation in Taveras’ right shin and ankle if some loose cartilage is causing troubles or if there has been tearing of the ligaments between the bones. Tears will be repaired. Mozeliak said rehab could be one to three months.

“I don’t think it should have an impact at all on next season” Mozeliak said. “It shouldn’t affect spring training.”
