It looks to me like Vogt's hands are tied because the front office gave Laureano $5 million so he has to play him at least part of the time, but the guy is a mess. The one thing they want him for is to hit lefties, but he's 4-for-23 with 9 K's. Against right-handers he's 4-for-27 with 12 K's.
He's hitting .091 with nobody on base (3-for-33). When the pitcher has no baserunners to hold and can focus solely on Laureano, he has no chance.
It's an unfortunate situation. Among the other right field options, Floreal is 3-for-4 against lefties with two doubles. Brennan is 2-for-7 with a double. Fry, who can play right field, is hitting .353 against lefties with an OBP of .586. Arias can also play right field and he's hitting .438 against lefties.
So Laureano is our fifth best option, and by far the worst, to play right field against a left-handed starter, but Vogt is stuck with him, for now at least.
