Smith wore a walking boot Saturday in New York's clubhouse and is scheduled for a CT scan Monday. He is batting .278 with 10 homers, 22 RBIs and an .858 OPS in 88 games this season, his third in the majors.
A natural first baseman, Smith has been starting in left field against right-handers to get his bat in the lineup despite his defensive shortcomings in the outfield. He is blocked at first base by Mets rookie slugger Pete Alonso.
Right-handed hitter J.D. Davis was in left field Saturday night against Pittsburgh Pirates righty Trevor Williams. New York selected the contract of outfielder Aaron Altherr from Triple-A Syracuse, and he was available on the bench.
