Pittsburgh's led 6-4 through five, but the Cubs tacked on a run in both the sixth and seventh innings to tie it. Pedro Strop (0-1) took the hill for Chicago in the top of the eighth and walked a pair before giving way to James Russell, who surrendered a walk to Pedro Alvarez to load the bags for Martin. His sac fly to right plated Starling Marte for the final margin.
Alvarez and Travis Ishikawa drove in two runs apiece for Pittsburgh, which took 2-of-3 from Chicago to start the season. Marte scored three times and stole two bags in the triumph.
