On Saturday it was an Adam Rosales single off K-Rod. On Sunday it was a Ryon Healy homer, again off K-Rod. And on Monday against the Angels it was a dinger by Jed Lowrie, his second of the night. The last time the A's notched three straight walk-offs was June 1-3 of 2004, with one of them coming on a homer by current bench coach Mark Kotsay. It's a hat trick, if the hat was made out of pies.
