DETROIT — Tigers general manager Dave Dombrowski accidentally hit save Monday, which inadvertently made his trade of pitcher Doug Fister irreversible.

“Nooooooooooooo! Shit! Shit shit shit shit shit!” Dombrowski shouted into his computer monitor. “God damn it! Now what do I do?”

It was reported that Dombrowki’s trade of Fister was a test to see what kind of players he could get back in a hypothetical transaction, with the full intent of closing without saving, so as to retain his starter as he continued to test the market.

“It was time for dinner, so I closed the window,” the GM said with a visibly red face. “That stupid window popped up asking me if I wanted to save before I closed, and without thinking, I clicked on ‘YES’ like a fuckin’ dummy. The same thing happened when I signed Torii Hunter. Luckily, that actually worked out. I hate these damn things sometimes,” he said, making a gesture toward a PC sitting on his desk.

Multiple inside sources have said that Dombrowski has since clicked that little checkbox requesting that he not be notified on closing the window from this point forward.

“We told him about that checkbox, but he never used it. We forced him to now,” one head-office source said. “I’m surprised it hasn’t happened more, to be honest. He would have traded Miggy that one time if the power hadn’t gone out.”

The NotGraphs Investigative Reporting Investigation Team was able to confirm that Dombrowski did try turning it off and on again.
