SCOTTSDALE, Ariz. (AP) Colorado Rockies left-hander Tyler Matzek has returned to spring training 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 due to control and confidence issues. He failed to get anybody out in his first spring appearance on March 2, was scratched from his next start and then left camp on March 14.
Matzek spent the past two weeks in Denver with the Rockies' new mental skills coach, former NFL linebacker and psychologist Dr. Rick Perea. Matzek said Thursday he took neurotherapy tests twice a day for two weeks while being coached about handling brain wave imbalances.
Matzek is uncertain when he'll throw next. He'll likely begin the season in the minors.
