Yeah, that confirms it for me. I'm about 95% sure that's a cricket frog. They're warty little buggers, but they're actually in the treefrog family. I've never seen one quite that color, but they come in a whole spectrum of variations, including reds, greens, grays, tans, browns, and blacks, with various spots and stripes.

It also looks a little like a juvenile green frog, but I can't make out any dorsolateral ridges and they shouldn't be that color in your area. Besides, juvenile ranids aren't usually so warty.
