The Giants placed Ahmed on the 10-day injured list Friday with a left wrist sprain.
Ahmed appeared to have sustained the injury on an awkward swing during an at-bat in the third inning during Thursday's game against Atlanta. Tyler Fitzgerald pinch hit for Ahmed in his next plate appearance. Casey Schmitt, who was called up from Triple-A Sacramento in a corresponding move, is starting at shortstop and batting seventh for Friday's game against the Reds, per Alex Pavlovic of NBC Sports Bay Area.
