The 27-year-old launched his fourth home run in as many games Friday to tie a club record, en route to a 2-1 win over the Chicago Cubs.
Having retired 14 straight batters, Cubs starter Jason Hammel gave up the solo shot to Bour in the sixth inning to break a 1-1 tie.
Bour has picked up the offensive slack since Stanton landed on the disabled list last week with a broken bone in his wrist, going 7-for-17 (.411) with four home runs and eight RBIs.
If his sudden power surge wasn't enough, it's the timeliness of his hits that have been truly impressive.
Bour's three-run ninth-inning home run Wednesday gave the Marlins a walk-off win over the San Francisco Giants. He followed that up with another three-run home run in the fifth inning Thursday that plated the eventual winning run.
Friday's win, the Marlins fourth straight, marked the third time Bour was responsible for driving in the winning run.
