Leury is an every day player. He can hit for average, has speed on the bases, has a gun for an arm, and can lead off.
Benetti said that he had about as many base hits as Castellanos does this year.
I'd bring up Robert and have Eloy, Robert and Leury as the starting outfield for the rest of this year and to start 2020,
No reason to give Palka another 60 AB's in the majors while Robert is held back.
Leury is good enough where the Sox can wait for an internal option (Basabe, Rurherford, Walker,,) to develop and replace him down the road, if necessary.
I would bring Madrigal up to play second, Rendon at short (until TA comes back) and Leury in RF. Stop switching Leury between infield and outfield.
