Good example of pitching to contact with his 2 seamer by Eflin.
However the 4 seamer high is not the wrong approach, it's a matter of balance for each pitcher.
Eflin can get hitters out with the 4-high approach, but it's not his comfort zone, but should be an arrow in his quiver.
Same way he needs both a breaking ball and a changeup.
You see this with Nola, who started this season throwing far more 4-seamers but has been throwing more 2-seamers lately, same way he needs his changeup to complement his curve. When he has all four working, he's untouchable.
And it's one reason it takes years for most young pitchers to develop consistency, you need to master enough variation (different pitches, different location of pitches) to keep hitters off balance three times through a lineup.
