Chipper Jones remains confident that his surgically repaired left knee won't be a problem throughout the season, but he is feeling some discomfort in the knee. "It was a bad day today," Jones said Saturday. "I didn't feel good doing anything. ... Some days I wake up and I can tell it's going to be a good day, and other days I'm going to have to fight my way through it." In hindsight, he wishes that he would have skipped some of the drills that proved more demanding on his knee.
