Naylor (shin/wrist) isn't in the lineup for Tuesday's game against the Orioles, Ryan Divish of The Seattle Times reports.
X-rays on Naylor's right shin came back negative following his early exit from Sunday's game against Washington. However, the Mariners will keep him out of action Tuesday, especially now that he is reportedly also dealing with a sore wrist. Miles Mastrobuoni will start at first base in place of Naylor, who appears likely to remain out of the lineup for at least a couple more days, per Jude.
