Pirates lead down to three

Pittsburgh remains on top of Boston after six innings. It's 6-3 for the Pirates after Boston pulled two back in the top of the seventh inning.
The two runs came via a home run, the game's third following Pedro Alvarez and Russell Martin providing the bombs for the Pirates.
Those players, along with the rest of Pittsburgh's starters, have since left the game. We're in the bottom of the seventh inning now.
