And since this is a Duran thread - he is not hitting RHP.
It's not "roster construction", or having to DH (he has 11 PA as a DH, none since March 31) and not even switching to CF on occasion, something he has done a lot the last couple years. And all this speculation about him needing to play regularly is just that - speculation,
Duran is hitting lefties pretty well (.739OPS), so roster construction doesn't seem to be impacting him there, And 20 of his 88 PA have come vs LHP, Interestingly, he has only 3 Ks in 20 PA vs LHP and 20 K in 68PA vs RHP. Big issue. RHP in general has killed Duran this year (.505 OPS)
Duran also has a .238 BABIP vs RHP. Last year it was .347. The year before it was .352.
The reason for the low BABIP? I'm glad you asked. Duran has seen his LD% from from the 18-25% range down to 6.9%, and instead he seems to be hitting more ground balls, which are successful for hits about 1/3 of the time as line drives. He also has a career high pop up thing going on, but that could be nothing at this point in the season.
Barrels are up, but hard hit% and EV are down. It's like he is just above or just below the ball.
So Duran has become a groundball machine that is struggling to hit RHP. He's been doing better since being dropped down in the 6-7 spots in the order, but I doubt there is anything to this. He needs to hit more line drives vs RHP.
Maybe keep him away from Fatse?
