Lewis, 22, is hitting .264/.331/.426 with six home runs, 23 RBI and two steals in just 33 games at High-A this season.
Lewis missed extended time due to a nagging right knee issue stemming from surgery performed last July, thus limiting his on-field production in 2017. His upside remains extremely high, but Lewis will have to prove he is healthy heading into the 2018 campaign.
