For reasons I can't begin to comprehend, my thoughts turned toward Ryan Vogelsong recently. I remembered how Vogelsong had such a great Spring Training in 2004 (26-1/3 IP and a 2.05 ERA). There was talk of him being a solid member of the rotation. It all fell apart and soon enough he was mopping up. So, in the tradition of Ryan "White Flag" Vogelsong, here is a listing of the Patron Saint of Lost Causes from each season of the Streak.
The White Flag for any given year had to appear in at least 20 games, including 15 relief appearances. Thanks to the magic of baseball-reference.com, I checked what the Pirates W-L record in each of those hurlers' appearances. The pitcher whose appearances marked the lowest W-L percentage was given the White Flag title for the season.
