Not baseball names, but last year I had the following students:
Amiyah - Pronounced with a long i (A-my-a)
Amiyah - Pronounced with a long e (A-me-a)
Miya - Pronounced with a long i (My-a)
Miya - Pronounced with a long e (Me-a)
Nia - Pronounced with a long i (Nigh-a)
Mia - Pronounced with a long e (Me-a)
And just for good measure, I also had 2 Jeremiahs. LOL
I am really good with being able to learn my students names, but remembering those pronunciations took me a while.
