UPDATE, April 17: Jack had a rough night last night, giving up 4 runs to the Nationals in the 8th inning. The updated picture shows Jack in a state of dismay and confusion as he watched his ERA rise to 9.00 against the lowly Nationals. More specifically, Jack is probably thinking, "I hope this picture isn't used for my 2009 Chachi card". I'm still holding out for a better picture, possibly from the 2009 Yearbook.
UPDATE, May 25: The Googles have led me to a better picture to use for Jack Taschner's 2009 Chachi card. This shot is apparently from Jack's appearance on May 13, 2009.
