Via an astute commenter: Baron Frost, of the Auburn Doubledays, a minor league affiliate of the Blue Jays.
It's no Bris Lord ("The Human Eyeball"), a player brought to my attention by commenter JL25and3 on the Banter and with whom I am now obsessed, but it's pretty good. Though, really, if Auburn Doubleday were a person, that wouldn't be a bad choice for Name of the Week either. Reminds me of one of my all-time favorite ideas for a blog post ever, from The Winged Elephant: "Wodehouse Character or Baseball Player?"
I am proud to report that I aced their quiz -- as well I should, since I have spent an inordinate amount of time in my life on both P.G. Wodehouse and, as you have probably noticed by now, baseball names. Personally I think the moniker that fits most seamlessly into both categories is Snuffy Stirnwiess.
