Braves right-hander Luis Ayala was placed on the 15-day disabled list on Tuesday because of an anxiety disorder. Ayala was 0-1 with a 3.86 ERA in five games with the Braves, all in relief. Braves general manager Frank Wren said Ayala began feeling ill on the team's recent 10-game trip and was found to have high blood pressure. Wren said Ayala has been placed on medication to treat the high blood pressure and already is feeling better. Carpenter did not appear in a game during a brief earlier stay in Atlanta before he was sent back to Gwinnett on April 22. All rights reserved.
