This is what it looks like when the A's call for ambidextrous pitcher Pat Venditte

There's no shortage of creative ways for a team to let a pitcher know that they'd like him to pitch. They could call him on the bullpen pay phone, they could flash a Bat-signal on the top of a skyscraper, they could tap an arm on the way out to the mound ...

... or they can do this weird, shaky double-finger thing that Athletics manager Bob Melvin uses to summon amidextrous relief pitcher Pat Venditte .

Venditte's ability (or abilities, as it were) have been well documented this season as he's gotten batters out with both of his talented arms. On Wednesday, Venditte made his 20th appearance of the season for the A's, surrendering three runs on one hit and three walks in a 9-4 loss to the White Sox.
