"Pedro Martinez expected to be named the Phillies' starting pitcher for tonight's Game 3 of the National League division series, but was giddy nonetheless after the official announcement was made."Hello, hello, everybody, hi," he said yesterday, grinning and waving while making an entrance into the interview room at Coors Field worthy of a stand-up comedian. "Which one is my chair?"The mood of the 37-year-old future Hall of Famer has been light since the Phillies granted his career a reprieve this summer, but his task is serious: keep the Phillies from falling behind the Colorado Rockies by two games to one in a best-of-five series. He will face righthander Jason Hammel.Manager Charlie Manuel chose Martinez over Joe Blanton, whom he seems to view as a key reliever in this series, and J.A. Happ, who suffered a bruise on his left leg when hit by a line drive Thursday. Happ appears to be the likely choice to start tomorrow's Game 4."I think he put two and two together last night and kind of knew, really," Manuel said of Martinez.Though Martinez has not pitched effectively since throwing 130 pitches on Sept. 13 and injuring his neck or rib on Sept. 19, Manuel believes the veteran is ready."I can sit here and tell you - very honestly can tell you - that I think Pedro is capable of going anywhere . . . from 85 to 100 pitches," the manager said. "And I think he can get you into the sixth or seventh inning if his command is good."Martinez said he felt healthy, and was excited to return to the postseason. He spent most of this spring and summer in the Dominican Republic, working to remain in shape if an opportunity arose."
