Above is a picture of 6-year-old Baylor Fredrickson, from the Little League team I coached last season -- the Red Wings we were called. Our team stayed together this year, but without Baylor. Baylor just vanished, which was a mystery, because a) he played with such enthusiasm, and b) we loved him and we thought he loved us back. Plus he was tough and smart: a born catcher. I just learned why Baylor Fredrickson didn't show up for opening day: he has cancer.

For Baylor to survive he needs to find a bone marrow transplant. To receive a bone marrow transplant he needs a bone marrow donor, in the next three months. This I just learned from Baylor's mother, Shari Fredrickson. "PLEASE, PLEASE, PLEASE,” she wrote to me, "reach far and wide to get our plea heard. When he says things like, ‘When do you think I'll be able to come home for good?’ or 'I can't wait to go play laser tag when I’m better, can we?’ I don’t really know what to say. As a parent you want to give your child the world. To give them the opportunity to achieve whatever their hearts desire. I just want to give him his life."

Baylor is half Japanese and half German. I don't begin to understand the science of bone marrow transplants, but Baylor needs a nearly perfect match, and that will likely come only from a person who is mixed race: half Asian, half Caucasian. The universe of his potential saviors is small: the doctors have told his mother that there is only one of them for every 70,000 Americans.

Now the good news: the world is newly configured to enable Baylor Fredrickson to find his match. There are supposedly 120,000 or so people who will have a random Facebook post more or less shoved upon them by Facebook. (For that, thank you Facebook.) [Ed: That "random" Facebook post Lewis posted on May 30 had been shared more than 330,000 times in five days.]

Among them, quite likely, is someone who can save Baylor Fredrickson's life. If ever there was an argument to end all arguments against social media, here it is.

Here's what you can do. If you are not half Asian and half Caucasian you might think of someone who is -- or simply forward this post or the Facebook post on to someone who might know someone who is. Don’t wait until tomorrow to do it. We have three months.

If you happen to be half Asian and half Caucasian, it's actually pretty easy to figure out if you can save Baylor Fredrickson's life. Anyone living in the United States who cannot make it to a donor drive can go to the Asian American Donor Program website. A free kit will be mailed to you, which you can use at home and send back.

Or you can get in touch with AADPs Executive Director, Carol Gillespie: Carol@aadp.org.

Anyone living outside the United States can find the program to register in each country at MarrowDrives.org.

Apparently sane human beings will happily blow money on a one in a million chance to win the lottery -- when all the evidence shows that winning the lottery doesn't make you happier. And yet those same apparently sane human beings hesitate (it sounds like trouble; they don’t have the time) to test their far better odds of saving the life of a delightful young boy, who is now 7.

I agree: it's not easy to win this sort of lottery. If you are the lucky winner you will need to spend 45 minutes in a hospital, to have some bone marrow cells removed from you. You won't feel a thing during the procedure but your hip will be a bit sore for a few days afterwards. It won’t cost you a penny but you won’t make any money either. On the other hand, I can almost promise you this: the winner of this lottery will, for some time to come, feel like a million bucks.
