Rockies' Matzek back after treatment for performance anxiety (Yahoo Sports)

Colorado Rockies left-hander Tyler Matzek returned to spring training Thursday after spending two weeks taking brain tests and undergoing coaching for performance anxiety. Matzek started the Rockies' home opener last year, but ended up in the low minors because of control and confidence issues. The 25-year-old Matzek spent the past two weeks in Denver with the Rockies' new mental skills coach, former NFL linebacker and psychologist Dr. Rick Perea.
