Rockies manager Jim Tracy collapsed at the winter meetings as he walked toward an elevator earlier this month. "I was scared, definitely. It did make me think about a lot of things," Tracy said. "I felt fine. Then, all of a sudden, I wasn't doing real well." Doctors diagnosed Tracy with a mild arrhythmia, or irregular heartbeat. He returned to Denver this week, undergoing a battery of tests with a cardiologist that all came back negative. "I am so thankful for the work done by (Denver cardiologist) Barry Molk. He was great with everything. He helped give me peace of mind," Tracy said. Tracy plans on returning to Denver in January for coaches' meetings before heading to fantasy camp in preparation for the Rockies' first spring training in Scottsdale, Ariz. "I feel strong. And I really do believe that I will feel better than ever this spring," Tracy said. "I can't wait to get the season going again. It was scary, but this could end up helping me."
