• Bob Welch, a Cy Young winner with Oakland in 1990, is helping the team's Minor League pitchers this spring and was invited to join Sunday morning's introductory meetings.
"We do like to try to celebrate our past here some, and that's one of the reasons he was there today, a great resource for our younger guys, a people person who loves putting on the green and gold as well," manager Bob Melvin said.
Welch served as pitching coach on the same Arizona team that employed Melvin as bench coach in 2001.
• The A's escaped Sunday's first full-squad workouts relatively unscathed in terms of injuries. After watching infielder Scott Sizemore tear his ACL on the same day last year, Oakland's biggest scare of the day was a minor one: Non-roster lefty Garrett Olson endured a cramp in his right hamstring, keeping him from throwing his scheduled bullpen session.
"He probably could have thrown, but we just don't want to go there this early," Melvin said. "We told them if they feel anything to tell us, because we want to get them to games."
