Did not get shared shutout achievement
 

I just won a game 10-0. Got a few hitting achievements. But I noticed that I did not get the "Shared Shutout" achievement, which I thought was always awarded when your pitchers throw a shutout. Here's the pertinent part of the boxscore, showing my pitchers and the achievements for the game.

My guess would be because you got 'Shutting Them Down' (which includes a shutout as a prerequisite) instead?

That makes sense. Thanks
