David Ortiz is happy with the pace of his recovery from knee surgery. Boston's designated hitter had arthroscopic surgery on his right knee Nov. 6 to repair damaged cartilage that has bothered him all year. "I think I will be training and running at full speed by January," he said Tuesday. "It was a simple operation." Ortiz hit a career-high .332 this year, but his 35 homers and 117 RBIs were his lowest totals in the past four seasons. He played in 149 games but sat out the penultimate game of the regular season after receiving a cortisone shot in his knee.
