This has been quite the stretch for large, embarrassing data breaches (or "incidents" -- depending on which spin you take). Now, the New York Yankees have been caught in the middle.
An employee accidentally attached a spreadsheet to an email that was being sent out to thousands of current clients. That spreadsheet contained the names, addresses, phone numbers and email addresses of current "non-premium" season ticket holders -- more than 20,000 of them. The Yankees' account executive tried to "recall" the message -- but unless the recipient was on Microsoft Outlook, that "recall" function just does not work. The team has apologized in a letter posted on its website.
