From the DDN

Paul Janish and the Dayton Dragons received bad news Monday morning when Dr. Tim Kremchek of the Reds discovered a tear in the shortstop’s right elbow, necessitating Tommy John surgery, which will take place Wednesday morning in Dr. Kremchek’s northern Cincinnati facility.

“I was pretty bummed out when he told me,” said Janish, the Reds’ No. 5 draft pick last summer and ranked the 10th best prospect in the organization by Baseball America.
Janish hurt his elbow Sunday when Burlington first baseman Rusty Brown had to tag Janish when a throw went wide of the bag. Janish was knocked off his feet and caught his fall by placing his right hand on the ground. He tried one practice throw when he went into the field and couldn’t continue.
