AT&T Park has been baseball's least homer-friendly stadium this year, though that hasn't mattered much to Nolan Arenado. It will serve as the final stage for Arenado and teammate Carlos Gonzalez's pursuit of the NL home run title as the Colorado Rockies close their season with a three-game series against the San Francisco Giants beginning Friday night. Arenado's 41 home runs tie him with Washington's Bryce Harper for the league lead, while Gonzalez has a career-high 40.
