Antonio had some stuff. He had some decent major league numbers in his career.
He briefly pitched for Albuquerque in 1994, and I got this signed when they were in Vancouver. A guy I knew had asked him to sign the same card the day before, and Antonio flipped out because he'd never seen a card of himself before! He gave the card to Antonio, and more packs were bought and opened to find a couple more of the card to get signed. Kind of a cool story, as I'm sure most of us fans would love to see our first official baseball card. Antonio didn't speak much English at the time, but he was super happy to have a card to sign.
In a funny side note, the lefty Al Osuna was on the same team.
