The Dodgers manager said he probably would have been just as furious at the 19th-inning safe call of home-plate umpire Jerry Meals as Pirates skipper Clint Hurdle was.
But that doesn't mean he's in support of Major League Baseball implementing instant replay -- although he does expect there to be changes in the coming years.
"How far are we gonna go with the replay?" Mattingly said. "This game is gonna take forever. People already complain about the length of games. Just how far do you go? That's the biggest issue with replay. Could there be some uses for it? Yeah."
Mattingly said the length of games was the best argument against replay, but added he appreciates the human element of keeping replay out of the game -- simply because the umpires are almost always right, he said.
That said, he sees changes on the horizon, and as long as it's not too invasive, he's not opposed. As for how a system would work, he joked when asked about an NFL-like challenge system.
"Which ones do you challenge?" Mattingly said. "Do you save them? Does it cost you a timeout? Or maybe it costs you a trip to the mound."
Mattingly said he felt for the Pirates to have a meaningful July game decided against them on a blown call. Had it happened to him, he said he'd have been out of the dugout arguing, too.
"Probably a lot like Clint at that point," Mattingly said. "If I could still get out there after 19 innings. That was tough because it didn't even look bang-bang."
