Calling it a big loss feels hyperbolic to me. Is this early 2025 decent Rhys, or June terrible Rhys? Are we replacing him with early good Jake Bauers or June terrible Jake Bauers (plus Vaughn)?
I don't know whether this will be good, bad, or a total wash. He did have a tendency to hit fly balls, which can be helpful (whether they go out of the park or not), but otherwise I hesitate to say it's going to matter one way or the other. If Vaughn can manage an OPS north of .700 for a month it's probably a net positive, unless his torrid July start was an indication that he was back on a hot streak.
