After four seasons in the Reds' chain, Contreras was drafted by the Mets in 1972. He progressed up the Mets' system, having a fine season at AAA Tidewater in 1975 (his first as a pure reliever)
This got him an invitation to Spring Training, Bicentennial Edition.

Unfortunately, Nardi not only didn't make the Mets, he was released! If you're not good enough to hang with Bob Myrick, I guess they had no use for him.
Luckily he kept going, eventually reaching the majors with the 1980 White Sox and then embarking on his coaching career.
(Why is Nardi wearing Ron Hodges's #42? Or is that an odd-looking 47? Huh.)
