Lewis has missed the last two games at High-A Modesto due to knee soreness but there is no structural damage, Ryan Divish of The Seattle Times reports.
The Mariners' top prospect recently resumed playing games at High-A Modesto after undergoing surgery to repair an ACL injury last July. According to Divish, Lewis' knee soreness stems from a play he made in the field where his leg crashed against the outfield wall Monday. The Mariners will be cautious with him and keep Lewis out until the soreness fully subsides.
