The Oakland Athletics have apologized for the food served to players in their farm system after Advocates for Minor Leaguers exposed recent post-game meals.

Photos were shared of the food served to players in the A's system. One showed a sandwich with little more than a slice of cheese mixed with lettuce and tomato.

"No employer would serve these meals to employees they care about," the Advocates for Minor Leaguers Twitter account wrote. "Why are the A's serving them to their future Major Leaguers?"

After the tweet began to go viral, Oakland A's president Dave Kaval called the food "totally unacceptable." He added that the organization had recently severed the agreement it had with a third-party vendor that served the players those meals.
