Profar could play second base if Lowrie departs, with Franklin Barreto remaining an internal option if a deal can't be worked out between the division rivals.
The 25-year-old Profar was once considered the top prospect in baseball but didn't play a full season in the majors until last year.
in 146 games, the youngster hit .254/.335/.458 with 20 home runs, 35 doubles, 77 RBIs, and 10 steals.
Before 2018, he never produced an OPS above .660.
Profar is only projected to earn $3.4 million through arbitration in 2019 and isn't eligible for free agency until 2021.
