John “Scrappy” Ramirez and Fernando Diaz have very different accounts of how their only sparring session went.

They’ll surely have different opinions of the outcome of their 10-round, 115-pound fight Saturday night as well. Ramirez remained unbeaten, but the crowd at Fantasy Springs Resort Casino in Indio, California booed loudly when he was announced as the winner of their very competitive bout by split decision on the Alexis Rocha-Anthony Young undercard.

The 27-year-old Ramirez (13-0, 8 KOs), a super flyweight prospect from Los Angeles, won by the same score, 96-94, on the scorecards of judges Jerry Cantu and Jonathan Davis. Judge Edward Hernandez Sr. scored their fight 96-94 for Diaz.

The 23-year-old Diaz (12-4-1, 4 KOs), of Bloomington, California, pressured Ramirez for most of their fight and landed his fair share of flush punches, only to be denied what would’ve been the most noteworthy win of his five-year professional career.
