Our long national nightmare is over. Finally, Clay Buchholz will take to a major league mound on Tuesday night for the first time since the day after the Bruins beat the Penguins in the Eastern Conference Finals. Yes, it's been that long. After innumerable bullpen sessions and rehab starts, the 9-0 righty will face the Rays in the first of three big games in Tampa. If he is anywhere near his early season form, it will be like a major free agent signing for the Red Sox.
