DETROIT -- The Detroit Tigers today announced righthanded pitcher Joel Zumaya underwent surgery yesterday at the Scripps Clinic in San Diego. Zumaya had an AC joint reconstruction on his right shoulder, a procedure performed by Dr. Heinz Hoenecke and Dr. Jan Fronek. He was injured moving personal items during the California wildfires. Zumaya will rest his shoulder for the next six weeks, before he will be able to begin an active rehabilitation program. He is expected to begin a strengthening program in three months and it is anticipated he will begin a throwing program in four months. The club is hopeful Zumaya will return to pitching at the mid-season point in 2008.
