The Cardinals plan to be conservative at first with using rookie Carlos Martinez as he acclimates to a relief role for the first time in his pro career.

Martinez pitched two innings over the weekend in Milwaukee, but the Cardinals were hesitant to use him in back-to-back days.

Rookie Seth Maness, who also joined the bullpen last week, pitched in consecutive days and has shown a “resilient arm,” pitching coach Derek Lilliquist said. Martinez is new to relief, and the Cardinals want to be cautious.

“It’s mostly just protection,” Lilliquist said. “Give him the rest he needs between outings. See how he goes about it with his throwing early before (batting practice) and go from there. He’s looked good – using two different heaters, attacking the zone.

"You don’t want him doing anything different than what he’s been doing. That’s the beauty of it.”

MOTTE HAS SURGERY

Cardinals closer Jason Motte had Tommy John surgery Tuesday at Mercy Hospital in St. Louis. The procedure was completed by team physician George Paletta, who had previously done the same ligament-replacement surgery for pitchers such as Adam Wainwright and Chris Carpenter.

Motte will miss the remainder of the season. Standard recovery time for pitchers is around 12 months, and Motte’s rehab could intrude upon next season.
