More than 70 years after the condition inspired Lou Gehrig’s “Luckiest Man” speech, Amyotrophic Lateral Sclerosis (ALS) has no known cause and no known cure. As some of you may know, my sister Jennifer has been bravely battling ALS, or Lou Gehrig’s Disease, now for a few years. Jen is less than two years older than me, and a big Mets fan herself. She has three young kids, and they’re Met fans. In recent months, Jen’s been keeping a remarkable and eye-opening journal of how this condition has affected her life.

The Walk to Defeat ALS, being held May 15 at Hudson River Park in New York, helps to support research and care for those affected by ALS, and spreads awareness of the urgency to find treatments and a cure. To support Jen and others affected by ALS, my brother Chris and I started a team, Meet the Jens, to participate in the event.

Please consider walking with our team, and/or sponsoring me, at the event this year. We have already raised more than $7,500 but with your help we can do much more. You can sign up to sponsor me and learn more about the walk, at this address (just click “donate to Jon” to make a contribution). While any donation would be deeply appreciated, as an added thank-you, I have a limited number of copies of the Mets by the Numbers book, which I’d be happy to personalize and send free to any donor contributing $30 or more to this great charity. Just let me know! Meantime, I hope to see you at the walk this year. Thanks!
