New Boston relief pitcher Koji Uehara officially became a member of the Red Sox today. Arguably one of the two best signings of the off-season (Stephen Drew being the other), Uehara can bring some real punch to the end of the Red Sox 'pen. The 37-year old righty has a career ERA of 2.89 over four seasons—with more than 45 fewer hits than innings pitched. And, to add insult to fried chicken, Uehara will wear Josh Beckett's number 19. Love it.
