Managers certainly utilize statistics and advanced metrics more than they used to. Back in the day, decisions were made off what your gut told you (whatever the F that even means) and your eyes showed you. Call the former being a robot if you must, but that's really short sighted as I'm sure if you went back and re-watched games from 1995 with the proper stats in hand, you'd realize the accuracy of the eye/gut wasn't very good.
That all said, pitching Suarez in the 8th and saving Hader for the 9th isn't a 'robot' decision, but instead an old school way of doing things. Some believe pitchers perform better when they stick with their routine and the old school way of managing was to use your setup guy in the 8th and closer in the 9th, regardless of where you are in the order. It's only be recently that managers have been scraping the traditional roles and putting their best pitchers in at the most crucial times. This change is almost 100% based on the statistics they now have at their finger tips as it appears that back in the day, people's guts didn't tell them to do that (even though it seems like common sense).
The robot would likely have suggested you use your BEST reliever in the 8th through the heart of the order and take your chances in the 9th. I'm not sure what the SD Manager was basing those moves off, but I really doubt it was solely based on the numbers.
