"You know it's going to be tough any time against a guy like [Harvey]," Bour said. "Dan came out and set the tone and threw up some zeros right away. We were able to score some runs there; that was big. Good way to start the series."
The Marlins are looking for a power boost from somebody other than Giancarlo Stanton, who paces the club with 13 homers.
Bour, who has provided a spark since being called up from Triple-A New Orleans, now has four homers and nine RBIs in 28 games.
The left-handed hitter also has gone deep in back-to-back games. He belted a solo shot on Wednesday in a 5-2 loss at Pittsburgh.
Harvey was throwing smoke all night, reaching as high as 98 mph. The Mets right-hander struck out six of the first nine he faced before Dee Gordon's bunt single to lead off the fourth inning. Martin Prado walked, and after Gordon moved to third on Stanton's flyout to right, Bour turned on Harvey's 91-mph slider.
The drive stayed fair near the right-field foul pole. Bour's homer was projected by Statcast™ to land 355 feet away and have an exit velocity of 96 mph.
"That was a situation where the guys in front of me did a good job, getting on base and getting in scoring position," Bour said. "Harvey, obviously, has got nasty stuff. That's not really a situation where I want to get behind. First pitch there and I was able to hit it good."
