That’s a good question. I don’t believe that run support is a sortable option in the Baseball Reference database. The answer has to be put there somewhere.
At first glance, Burnes is actually getting good support, at 4.50 runs/9 IP.
That’s actually above the National League average of average of 4.41 runs scored per 9 innings.
The problem is that a few big games are skewing the results. In one start, Milwaukee scored 19. In two others, 10.
If he’s getting 4.50 per 9 IP, and he’s thrown 143 innings, that comes out to 15.889 9 inning games, and 71.5 runs scored by our offense. Round that to 72.
Take away 29 runs and 27 innings, that leaves 43 runs in 116 innings. If my math is correct, that means in his other 20 starts, he’s gotten 3.33 runs per complete game from our offense.
