Word out at the Coliseum today is that second baseman Mark Ellis will miss the remainder of the season with his right shoulder injury. Details are scarce right now, but Ellis is scheduled to visit Southern California-based doctor Lewis Yocum. Surgery is a possibility. That means the opportunity continues for Eric Patterson and Cliff Pennington to prove themselves at a position that could be wide open if Ellis doesn’t return in 2009. He can become a free agent at season’s end.
