Kevin CummingsIf not at the top, certainly near it is the aforementioned Mario Mendoza, after whom the infamous "Mendoza Line" was named. (http://members.tripod.com/~alpepper/mendozaline.html)
It's easy to say a guy who played one year and had an 0 - 4 record or a poor batting average is the worst, but Mario Mendoza was consistently awful over the course of nine straight years.
And it's not like he was just a crummy batter; he was no great shakes with the glove either!
