Franklin Gutierrez now knows what caused all of his stomach problems over the last year. Seattle's Gold Glove center fielder was diagnosed with irritable bowel syndrome. "I just need to be healthy now. I need to be here," Gutierrez said. Gutierrez visited the Mayo Clinic in Minnesota earlier this week, where he was diagnosed with irritable bowel syndrome as the cause of his stomach issues that first popped up last summer. There's no timetable for when Gutierrez might begin playing again.
