McCarthy signed a one-year, two-way contract with the Sharks on Thursday, Curtis Pashelka of the San Jose Mercury News reports. After opening the past season with AHL Chicago in the St. Louis organization, McCarthy finished up the campaign at AHL Worcester, where he had played the previous five years. He'll stick around with the organization that drafted him, but his middling production in the minor-league ranks likely won't put him on the cusp of a promotion.
