Fabian could be a good RH platoon with elite defense in a LH heavy OF, assuming the OF is something like Cowser/Mullins/Kjerstad next year. Also possible Santander is back, which would be nice with his switch hitting ability.
...so sort of into the next discussion on "things we need to do in the offseason".
I like Fabian but I agree he'd appear short term as more of platoon or 4th OF type bat. I'd probably want to see him more at AAA next year and I think Slater has been interesting in his short time here.
Whether you use a guy like Slater or Michael A Taylor or McKenna (type of player) that's fine as your 4th OFer to get Fabian a little more time at AAA in 2025.....
....but I'd view a Cowser-Doyle-Kjerstad OF with Slater(Fabian in 2026) as a most reasonable type plan.
