The Brooklyn Cyclones are celebrating one of the greatest sports pranks ever: The Sidd Finch story from Sports Illustrated. From the Cyclones website:

“On April 1, 1985 the Legend of Sidd Finch was born when Sports Illustrated published an article detailing the story of the lanky righthander with the golden arm who was going to change the game of baseball with his 168 MPH fastball.  Sounds too good to be true?  Well you’re right.  But our Sidd Finch Bobblehead Night on August 26th, that’s no joke!”
