Description: Martin "Wags" Wagner, an aging catcher relegated to a minor-league affiliate of the San Francisco Giants, is offered a new assignment-take a promising young pitcher under his wing and show him the ropes. Martin's manager is cagey about the new player, giving only his name, Andrei Dinescu, and his country of origin, Moldova. Despite the mysterious circumstances, Martin accepts the assignment, hoping to earn a return to the big leagues.
After his first bullpen session with the new pitcher, Martin is stunned by Andrei's lack of physical ability and his unfamiliarity with baseball. However, with each passing week, Andrei's strength and skill grow exponentially, and his miraculous leaps in both ability and pitch velocity frighten Martin. His fear is compounded by the organization's obvious attempts to keep Andrei separated from the rest of the team. When Martin discovers the shocking truth about Andrei Dinescu, he realizes his path back to the big leagues is one stained with horror and blood.
