Ah, yes. The classic knee pads and bats pose. I always wanted to see someone go to the plate like this, just to see what happened. Anyway, Bob Natal ended up sticking with the Marlins, playing five seasons for them as a mediocre backup catcher (is there any other kind?). In 1990, this kind of appeared to be his destiny, as he never hit for a particularly high average or had a high OBP.
Penn was a flameout first baseman who was picked in the 8th round of the 1987 draft; what you see here represents the pinnacle of his career, as he was gone after 1990, having batted just .247 with a .687 OPS.
Yorkis Perez is another player who eventually caught on with the Marlins after a short stint with the Cubs. As I recall, he was a mid-level prospect at the time more revered for his “stuff” than his numbers. But hey, he hung around in the majors in one form or another for 12 years, so he did something right.
Hector never made the majors; this is also his apex, as he was done after this year. I’m not quite sure what happened to him, though, as he had a decent record and peripherals. Perhaps an injury long lost to the mists of time.
