I had this guy:
Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Lyle Bolling
He was tricky because on the lineup page, he has "(R)" next to his name. He had SS ratings, but threw lefty. I mistakenly played him at SS for quite some time before I realized what a dumbass I was being. Of course, after he later moved on, other owners continued the practice...
I also had a buddy of mine growing up who threw lefty and hit righty - played 1B. One game, just for the heck of it, he hit lefty and jacked two home runs. I told him he was a dumbass....
