Zito will sign a minor league deal with the A's and come to spring training, reports Susan Slusser of the San Francisco Chronicle.Zito last pitched in 2013 with the Giants, posting an ugly 5.74 ERA over 133.1 innings. He took a year off of baseball and while he is likely a long shot to make the A's major league roster, A's fans will certainly enjoy getting to see him in Mesa this spring donning the green and gold again.
