Yamamoto (forearm) has just a slight chance to return to the Marlins this season, Andre Fernandez of The Athletic reports.
Yamamoto has been dealing with a forearm strain since the end of August. Previous reports cast his return in a more favorable light, with the expectation being that he'd make a start in the instructional league before being activated from the 10-day injured list, but president of baseball operations Michael Hill seemed to be more pessimistic Tuesday.
