Chris Carpenter tossed his fifth official bullpen session of spring training on Thursday.
Carp reported no problems and pitching coach Dave Duncan seemed pleased with the showing. "It’s kind of natural that he will work toward throwing at 100 percent," Duncan said. "I think we’ll see that his adrenaline will be doing the first time he faces hitters. He’s been fine. … Step by step. The next step for him is throwing to hitters." Carpenter will face hitters on Saturday and his scheduled to make his first start on February 28.
