ST. LOUIS — Cardinals RHP Chris Carpenter took a step forward in rehabbing a shoulder injury that has sidelined him all season, throwing off a mound for the first time.
The 2005 NL Cy Young winner threw 26 pitches Wednesday. He's scheduled to throw again Friday, then a few more times next week.
"We've been getting positive feedback from all his workouts, and every step that he's taken it's always positive," manager Mike Matheny said. "But let's try not to put too much pressure on him that one thing means anything.
"We just want him to continue to get better and get him back as quick as we can."
Matheny said there was no firm timeline for Carpenter's return.
The Cardinals are hopeful that Carpenter, who was 11-9 with a 3.45 ERA last season then went 4-0 in the postseason for the World Series champions, can return after the All-Star break. Carpenter broke down in spring training with a nerve-related ailment that sapped strength in his throwing shoulder after pitching 2731/3 innings in the 2011 regular season and postseason.
Carpenter, 37, said the intensity level was comparable to a session before the team reporting for spring training in mid February. He said everything feels fine and he is guardedly optimistic he'll pitch this season.
LASORDA IMPROVING: Hall of Fame manager Tom Lasorda said he feels good as he recovers from a mild heart attack he had last week in New York. Lasorda, 84, has been resting at home in California since being released from the hospital Thursday, three days after he fell ill.
SECOND PICK SIGNS: The Twins signed second overall pick Byron Buxton, 18, a Georgia high school outfielder. Buxton received a $6 million signing bonus, the biggest contract so far in this year's draft class.
MORE SIGNINGS: The Rockies and 10th pick David Dahl, an Alabama high school OF, reached a $2.6 million deal. The White Sox will give a $2.475 million bonus to Texas high school OF Courtney Hawkins, the 13th pick. And the Giants and Mississippi State RHP Chris Stratton, the No. 20 pick, agreed to a $1.85 million deal.
