Historically Hendricks has been a 5 innings guy. He's been really effective for 5 innings and runs into trouble in the 6th. In a lot of his games he doesn't even record an out in the 6th. Hendricks history isn't that vast, and even with as good as he was in 2016, the trend somewhat held. Looking at this 1-5 innings he was a way below 3 ERA, and in the 6th he was over 4. He wasn't getting shelled or anything, but there was reasonable risk for letting him go past the 5th inning. In game 3 he was pulled in the 5th inning, but he was already up to 85 pitches that game. They went into game 7 with all hands on deck, stud starting pitchers ready to pitch an inning or two, and a goal of getting Hendricks through 4-5 innings. You can argue it was overly conservative, but it did make sense.
