I think Elias wants stronger defensive outfields who can hit.
Definitely think the main motive was strategic. Elias continues to build my trust more and more.
I think the discussion of strategy will take some time to develop.
First, Elias is an employee, he can make an argument, but this is more than a Baseball Operations decision. That said, he could certainly make an argument. The Blue Jays are a younger and heavy RHed team. The Yankees core hitters (DJL, Stanton, Judge) are RHed. BOS has been more RHed than LHed in recent years. I guess you can run the math and figure out what your run prevention looks like with current and new and argue that's an "improvement in your pitching".
The Orioles have also been more LHed with pitchers recently so more LH pitchers means more RHed batters. Do you look at John Means and see where balls are landing to left-center and argue that he's a run better, let's get an extension done? I'm all for it.
...but the Orioles have also tended to be more RHed recently and maybe that changes with some guys coming in the future, so it could impact your run scoring too.
Does anyone think they are trying to attract FA pitching with a less hitter friendly park? That would seem to be the opposite of their approach.
Maybe it's as simple as "if we move the fences back our ERA goes down 0.80." I guess there's plenty of time to break it down....but you don't get credit for 'improved pitching' when your answer was to move the fences back.
