The headline does not deceive you. It really is time for another Big League Stew Photoshop contest, one that features the best grand prize we've ever put up for competition. Before we get to the Mizuno-provided booty, though, here's what we're asking you to do. Take the above picture of Matt Cain swashbuckling against San Francisco Giants teammate Jeremy Affeldt earlier this season and Photoshop it into something far funnier and more creative.

With Cain looking to attack, there are no shortage of scenes you can dump him in. (Don't be afraid to get Affeldt involved, either.) The rules : Send all entries to bigleaguestew@yahoo.com by Sunday, Aug. 19 at 11:59 p.m. PT.
