Kelly is working off a team option for 3.5MM next year, and the prevailing assumption is that the Tigers will pick up the option if Kelly improves on some things and fulfills his prospect promise during the final six weeks of play and over the winter into spring training.
But I wonder if this move might actually be more about whether Dingler improves enough over the winter and during spring to warrant coming up to Detroit, if not in April, then early enough to make Kelly expendable.
Dingler will be 25 in November so we’re getting to the SOGOTP stage, so maybe they’re thinking if he looks really close in late March, they spin off Kelly and go with something like Rogers-Sands for a few weeks waiting for him; and if Dingler still doesn’t look close, they just pick up the option on Kelly, let Dingler keep developing, and start beating the bushes seeking another catcher-of-the-future.
